How To Set Ignition Timing Without Timing Light

Turn the distributor counterclockwise until the test light comes on (just as the contact points are opening) and tighten down the clamp. So I have a basic timing light without ability to dial in timing, so light only. Ignition timing is not only a key to power, it's also a major player in gas milage and overall drivability. So, to get set up, you need the bike warmed up, the clear plug installed in the timing hole (hole in left case just below and between the base of the cylinders), the timing light power connected to the battery, and the timing light pickup attached to the front plug wire. Connect the timing light ground connection to a suitable grounding point. First, run a check to see what the current ignition timing is, then you can advance or retard the timing from there. I have an 93 FXR. The timing mark should line up with the timing pointer, double check to see if a mark is present at this location. 001" off the key will result in 5 deg timing change. Apr 1, 2015. When I pulled the thing apart, the ignition was set with the plate at full clockwise. G40 PY is similar. Pull the distributer body from the engine before rotating your engine's alignment to TDC. However, the distributor (timing device) must be able to apply the spark at the right time and for the right duration throughout the entire rpm range. Fuel and type, humidity, compression, coil output. Raise RPM's to at 2k. rotate dizzy until you read 12* on the crank (also if your crank pully doesnt have a 12* mark you can see the distance from 0* to 16* or 18* and then a little math and a limp measuring tape you can find 12 easy and then make a mark on it to see with the light) done. Once a timing mark is present at TDC you can use an advance style timing light and set it to the number of degrees of advance you would like and adjust and set the timing. If you turned the engine off to hook up the above stuff, start it again. The timing must be set when the idle speed is as low as possible, i. My question is, is there a standard how ignition advance is. Running a stock 1. There is an idle figure which would be probably around 8-16deg BTDC, and a figure for the maximum advance which in your bike's case will be the 23deg BTDC at 3000rpm. Find the notch on the crank pulley and draw a mark on the slash guard to align with it. Doesn't work in my humble opinion and will have you way way advanced. Selecting the Right Timing Light There are few different kinds of timing lights available. I will stick by what I said: "You can't accurately set the timing of an electronic ignition system statically. If the running timing is accurate, try reducing the cranking timing setting. The red mark on the crankshaft pulley should be aligned with the pointer on the timing belt cover. Bolt the degree wheel to front of engine crankshaft and tighten slightly, use Existing timing mark pointer if one is there , if not ma. THIS PROCEDURE IS NOT ADVICEABLE BECAUSE IN Page 10/35. Re: 1991 SDV Ignition Timing. I've taken some time of work so I can get on with some jobs on the Stag one of them is to give it a service and general check over, since I've only had it 4 months so I checked the ignition timing with a timing light (Im assuming that the pick up sensor clamps on number 2 lead) and it's firing at about 18-20 degrees. Removed the wire and it came back up to 4*. Although my car seems to be starting and running just fine now, I finally got hold of a timing light so I wanted to check the ignition timing. 0L motor is the same as any other motor with a distributor. By Ken Juran. Turn the ignition off. Ignition timing can also be precision adjusted without the use of a timing light. I believe the electronics in the coil module can as well effect the timing advance, does anyone know how many degrees of variability. it Re: Setting the ignition timing on a Mercruiser 4. Your engine will rev up for a second then go back down to normal idling RPM's. For example with total timing set at 32° and the rotary dials set to "2" and "9". My question is what mark to use. 10 degrees is where its suppose to be. If it does, back it off 2* and drive it again. If there is an advance or retard in the ignition, at a low RPM, I couldn't tell you. It's different from ignition timing,it's got to do with when your valves are opening and closing. Now point the timing light at the engine's front cover and observe the mark. Firstly, make sure the engine's at normal operating temperature and that the A/C is off.

What the light shows is running timing, which takes into account mass in motion, electrical resistances and such that can make timing change slightly while operating. Remove all Step 2. " Just because you can set the timing statically close enough to get it running doesn't mean it is close enough to hit the byways. With the trans in Park and the dial-back light hooked up, upon light acceleration, the timing literally retarded about 10 degrees and then quickly advanced. When I pulled the thing apart, the ignition was set with the plate at full clockwise. there will be a timing mark on the harmonic balancer. That probably will get you into the ballpark where the engine will run, but with a bit of additional effort you can improve the engine’s power and performance. How do I know what to set the adjustable timing to? I use an LED display from a knock sensor system made by MSD. Lock dist down. Tuning an older Volvo:. further, this is the high point on the cam. The timing is not adjustable at all. (DBTDC) Your ignition will fire at that point regardless of the rpm the engine is running. Mechanically the engine must be set to Top Dead Center. They set an appropriate timing when the engine is made, so you receive as much possible power without surpassing the legal emission limits. The ideal vacuum advance is the maximum possible without excessive pinging. A faulty ignition module can affect ignition timing, resulting in an engine that misfires and runs. Basically the timing chain in every vehicle is set up on the following principal No 1 cylinder is at TDC on compression stroke " meaning both valves intake and exhaust are closed and the ignition rotor should also be lined up with No 1 ignition lead. If this happens set timing to 15 degrees, allow the engine to fully warm up, then disconnect the set timing connector to set the base timing to the. Keep in mind when adjusting the timing, you have to turn the distributor clockwise to advance and counter-clockwise to retard. Your six-year-old econobox is starting to show a bit. Many factors such as engine temperature, load, RPM, fuel ratio, etc. Move the timing light leads to each of the other two spark plug wires and check the timing again. Ignition Man, your a ski eyes missile man in my books. Spark plugs and a fuel smell are telling me its running too rich, but before fiddling with the fuel adjustment on the carb, I believe (from my reading on the interweb) that its best to ensure that the timing is set first.

Start with the screw in the middle position, adjust the ignition timing to 15 degrees by moving the distributor body, adjust the idle rpm (back) to 700+/-50 rpm by moving the slotted screw/pot - which moves the ignition timing via the ECU. Bolt the degree wheel to front of engine crankshaft and tighten slightly, use Existing timing mark pointer if one is there , if not ma. Unfortunately I can’t find the paperwork for the electronic ignition. They arn't as expensive as the set of new pistons you'll need if you get it wrong!!. Ignition timing is the process of setting the time during the compression stroke when a spark will occur, relative to piston position and crankshaft angular velocity. Setting ignition timing without a timing light is considered by some to be inexact and dicey. A timing light is the most common way to check ignition timing. Use this number for your WOT timing. When satisfied, put the light down and tighten the distributor clamp. Cleaned my harmonic balancer, stuck on the tape, timed my car and then it disappeared. Adjust timing for 5 +/-2 BTDC. You can not set your timing without a timing light. To insure proper alignment of the distributor, perform the following: With the ignition OFF, install a scan tool to the DLC. Basically the tech plugs in the scanner, connects timing light, jumpers two pins on the diagnostic port in the engine bay, tech will raise RPMs to 1000-1500 RPMS for several seconds, verify RPMs return to regular idle speed and reverify timing. Remember, the timing belt only keeps mechanical timing - that of the cams to the crank - it has no bearing on ignition timing. After that's jumpered, you can connect a timing light to the #1 spark plug wire and the battery terminals (power source for the light). Hey there, Dangar Stu here. To set the dwell, remove the distributor cap and rotor, ground the coil wire and remove all the spark plugs from the engine. Once the marks are aligned, you can read the timing light to see where your ignition timing is currently set. 3 EFI if it's TB4 you need to start the engine and let it warm up, ground the purple/black wire that should be up front next to one of the valve covers, set base timing, then remove the ground from the wire. All timing starts from the same place. Just a thought. With a points distributor static timing is easy to set (with a timing light connected to the LT lead and earthed - rotate distributor until points open/light goes on). (3) Set the timing light.

In the version 1. Ok, from what I understand about how to set up engine timing, you first have to have the engine at Top-Dead-Center on the compression stroke. Very easy to get close to factory timing without a timing light on a CA18 anyway. Hook up the timing light to the #1 plug wire. The engine must be running to check the timing. With modern point-less ignition systems the basic timing is set by position of the coil and flywheel magnets relative to TDC of the piston. Base ignition timing and timing advance are controlled by the Powertrain Control Module (PCM) Because a conventional timing light can not be used to adjust distributor. So I am in the process of timing the CB360 with the Hondaman Ignition Kit installed. Check ignition timing with a timing light. I believe the electronics in the coil module can as well effect the timing advance, does anyone know how many degrees of variability. Setting the ignition timing advance on an engine with a distributor style ignition system can be confusing if you don't know what you're looking at. The ET cam has a single cam lobe that opens the points for 15 degrees of rotation. MSD will tell you the same thing. Base timing is checked by disconnecting a wire connector in the computer wiring harness. Setting Ignition Timing on 246 DIno. Now point the timing light at the engine's front cover and observe the mark. The above is a graph of flame speed in meters per second (m/sec. Perfect for car, motorcycle, all two-stroke and four-stroke gasoline engines, easily operate on 12V ignition systems. It's not as hard as it sounds (no pun intended). If your DelOrtos each have the same jets and settings, I guess that's why swapping them makes no difference. Cam timing is what determines when the valves open and close with respect to the position of the pistons in their bores. Before you can check the timing, a jumper must be set in the diagnostic module, which is on the left fender well. I'm not sure what the firing order is though so hooking up the timing light was based on my past experience. If the ignition timing is not within specifications, loosen the distributor body installation bolt and adjust the ignition timing by turning the distributor. I have other GM trucks the timing is set by disconnection of one wire to set base timing, A 2000 chevy does not have coil pack, where timing is not an issue when a coil pack is used.

I have two diifferent oem shop manuals and they both say different things. Mark the spark plug wires for the cylinder number using a short piece of masking tape on each wire. Suddently, the timing marks for TDC and 5ATDC disappeared, as did the ones for 30 and 35BTDC, and my digital timing light was indicating 60 degrees of advance. Find the notch on the crank pulley and draw a mark on the slash guard to align with it. Connect a timing light to the front cylinder. If they're worn or hard to see, you might want to mark them with a bit of white paint so they're easier to see. don't do it too much or you can cause backfire or dieseling after shut downs. You can then turn the distributor 1/4 of a turn clockwise to advance it enough for the motor to start. You use a timing light which is hooked to the #1 spark plug wire and the battery. If the light does pulse, replace the coil. On world models, idle speed is 950-1050 RPM. i wanted to have the timing like 38 degrees BEFORE TDC total, but when i put the initial timing to 3 degrees, the vacuum advance canister. The only marks are available on the flywheel. Record the timing reading and the vacuum reading. The vacuum advance works as I checked that by sucking on the end of the pipe and watching the timing mark under the strobe. Timing specs vary, but a good rule of thumb is to set the timing at 12 degrees advance once the engine has started up for the first time. As RPM increases, the engine requires different ignition timing due to a list of changes that occur to the air/fuel mixture entering the cylinder. Turn the ignition switch to the on position. Connect the vacuum hose to the vacuum control unit. For the finest possible timing adjustment, service the advancer, adjust the cam chain tension, then set the dynamic ignition timing using a stroboscopic timing light. You see the zero on the tape; the number on the right side of it indicates the downward and the left side shows the upward motion of the piston. I just did the math and came up with 2 degrees. Just for your edification, I'll go into the what's what on timing on this page, but if you have zero interest in all of the complexities of ignition timing, why it's important to how well your engine is running, and why it can be disastrous if it's off, you should skip all of the tech talk and simply get out your manual to. The timing will be. I also have DelOrtos. To me this means 12deg at the crank but the timing flywheel timing marks conflict with this idea and suggest that its 6deg at the crank. there, your initial timing is set, but.

To do this unscrew the pin that sticks out of the timing gear cover and insert the pin end into the hole. Timing dynamically is fairly simple and is the best way to time your engine. If the light looks bright and steady when the misfire occurs, then the problem is in carburetion. Not sending any spark would have to be the coil which is really easy to swap and a completely dead one would also fail the basic ohm test or the main module which is also mounted below the rotor. The rotor should be pointing directly at the #1 wire in the dist cap. The timing is not adjustable at all. Connect the vacuum hose to the vacuum control unit. FURTHER CHECK IGNITION TIMING Ignition timing: 7 - 24° BTDC @ Idle (Transmission in neutral position) HINT: The timing mark moves in a range between 7° and 24°. But when I put timing light on it shows crank pulley at about eighteen or just above the T. turn the distributor until it sparks. When I set the timing by attaching the pickup for the light to the 1st coil pack, and the MAF is plugged in, car warmed up, the signal is somewhat jumpy, but when i adjust it to 15* on the crank, the CAS is maxed out almost all the way advanced (no gap between the CAS adjustmetn and where it bolts to it, its maxed all the way out almost). That probably will get you into the ballpark where the engine will run, but with a bit of additional effort you can improve the engine’s power and performance. Connect the timing light power leads according to manufacturer's instructions. FIVE DIFFERENT ADVANCE CURVES - You can advance slowly to dial out pinging on high compression motors or bring the advance in quickly on quick revving motors or select a. You first must set the point gap, and I always set mine to. Using a timing light, check the ignition timing. The initial timing should be 12°11°BTDC (Before Top Dead Center). By John Copeland. There are two types of timing in an engine: cam timing and ignition timing. The adjustable pushrods have to be added, and at that, changing tappet plunger depth doesn't have the effects that it does on chevy V8. In this case, the engine is idling at 17 degrees of initial timing at 781 rpm. Idle speed settled down to around 750 rpm (normal). 030″) for every step colder plug. A loose or weak engine timing belt that jumps time can cause the ignition timing to be off. NG >> GO TO 3. your plane/jane light will set the timing fine. All this mod does is change the base timing and. It requires the use of a professional scan tool to observe the "Cam Offset" PID and adjust it to "0". That way, you can still double-check timing without timing. If your engine's real timing matches what you dialed into the light you will see the new mark on the cup showing through the hole directly beside the post (which I left out of this picture, but its hole is there). The engine started, but was a little rough. To do this unscrew the pin that sticks out of the timing gear cover and insert the pin end into the hole. 1 ignition wire and point the light toward the pointer on the timing belt cover. Set the static timing to 10 degrees BTDC using only a bulb or a meter. I hooked it up to the first or front cylinder. To adjust the ignition timing on the 2. The guy in the video said he did play with the timing advance a few degrees and found no difference. My initial timing is set at 12* Idle timing is at 14 right now. Hook your timing gun up to the power and ground terminals on your car's battery, and hook the sensor that accompanies the timing gun to your number one cylinder spark plug wire. 5:1 stock M10 and found that when I use the factory timing settings, the engine runs well - but it is no barn burner. ignition timing should be set at 10 deg BTDC at idle (800 rpm). Now set the Centrifugal timing. Use a timing light with vacuum advance disconnected. All that is required on this light is to use the up and down arrows to set the mark on the balancer with the zero mark on the timing tab and total timing is displayed. Base ignition timing and timing advance are controlled by the Powertrain Control Module (PCM) Because a conventional timing light can not be used to adjust distributor. The timing marks are on the damper, I have a mallory distributor (if that helps) and the timing light is is a "make waves" cheapy 1978 BRONCO 460. Keep it at idle speed, about 800 rpm] Check ignition timing with a timing light. Go to the timing marks. The ignition timing marks are located on a tab attached to the engine. Put it back in. I then set the timing on the balancer at 10 advanced. Reply by L1ftmech. There is a mark or notch on the distributor housing that the rotor should be pointing to when the e.

Now rev the engine just a little while observing the timing marks with the light. In older models, particularly those built in 1985 and earlier, you’ll need to rely on a timing light to set the timing once the new distributor is in place. Check the idle speed and adjust if necessary. I unplugged the spark plugs, turned on the electricals and started to crank the engine. loosen up the distributor and hook up a spare spark plug to the #1 plug wire. This is usually done statically and does not require a timing light (Darn!). I recently rebuilt a 9. If you don't have a ohmmeter, set the engine on the compression stroke, then remove the distributor cap and put some cellophane from a pack of cigarettes between the points. The timing belt cover should have a pointer. It is advisable to check your advance curve using a timing light and check the centrifugal advance, and if fitted, the vacuum advance, are both working correctly. If there is no oil vapor in the cap to indicate the seal has broken down, that you provide a few drops of light oil to the distributor shaft and inspect the reluctor for corrosion, that the vacuum advance still works (you can pull the hose and suck on it to. (4) Start the engine and run at idle. Rev the engine to 2800 rpm - timing should be around 38 deg. Product description. Put timing light connector on #1 spark plug wire (nearest the front of the car). NOTE: To set timing correctly, a remote starter should not be used. With the light in place, the ignition should be turned on. Im still new to link and havent had alot of experience with it. Check for hard cranking, check for spark knock. Start engine and allow to reach operating temperature. With AutoTrigger this is now an easy procedure, with only one variable requiring setting, the Trigger Offset.

Crank engine so #1 cylinder (front) is coming up on compression. The procedure will outline how to get the vehicle’s engine computer into a base timing mode which will allow you to adjust the ignition timing correctly. Ignition Timing is the process of setting the angle relative to piston position and crankshaft angular velocity that a spark will occur in the combustion chamber near the end of the compression stroke. Settings/MegaTune. Now do the mod and recheck it will be 13 to 14. Then you can remove, repair/replace, insert again and fine tune with a timing light. Either attach your strobe light to no 1 plug lead, or (if you don't have a light) remove no 1 plug lead and fit a spare spark plug to it (with the body of the plug suitably grounded to the engine). This is the initial amount you have the ignition timing advanced. Read the timing at this point. The other type of timing, ignition, on an X1/9 is just like on most other cars, getting the spark delivered to the cylinder at the right time as shown to you by a timing light. Like, they mean 28° FROM idle ignition. Although I set the timing with a strobe light do I need to set the dwell angle as well. Set up a timing light. If your ba lancet had timing tape on it you would adjust with a regular timing light until the line matched up with the 8 degree btdc line. (Fat) Investigating the only light I found that was MSD compatible was MSDs' and it was very pricey. After timing was verified the fuel pump relay was reconnected and the engine immediately started. Loosen the dist. - Record the timing reading. Okay, I could get under the car and mark the groove on the pulley with white paint. Digital Timing Light Innova Professional Mechanics with Bright Xenon Strobe + Advance Dwell Tacho - 590-518. To time the Boyer, set the timing plate so that 40* is the maximum advance you hit when you turn up the revs, no matter where that occurs--crank 'er up until the mark stops moving. He would play with the dizzy while idling and and rev the motor. If you turned the engine off to hook up the above stuff, start it again. Ignition timing: 8 - 12° BTDC @ Idle (Transmission in neutral position) c. After adjusting the ignition, the vehicle should run for a few minutes to make sure that it works properly. That number should be entered to Max and Main Timing. To time the Boyer, set the timing plate so that 40* is the maximum advance you hit when you turn up the revs, no matter where that occurs--crank 'er up until the mark stops moving. The car cannot/should not be cranked without the ignition coil being grounded by a spark tester (thanks to Randy for the feedback). Receive free standard shipping on orders over $35 to addresses in the continental United States. Exact crankshaft position Timing marks can be identified and mark using a degree wheel and locating #1 cylinder. When i set timing the light gives you a pretty fat line on balancer. Will a car start if timing is off? Ignition timing is the setting of the spark plugs to ignite when there is a compression stroke. Remove the blue temperature sender wiring and rev engine over 3000rpm 3 times. Set the engine at TDC, remove the dist cover. in this video you will learn how to set ignition timing manually without using timing light. This is the scratch mark you need the rotor to point to. It will now be electronically controlled by the ECM and a. Optimize initial timing with the mechanical /vacuum advance curve and your engine will make more power, run better, and get better fuel mileage than ever before. It cannot be adjusted on a stock engine. In order to set the timing at 5 degrees ATDC, am I correct in assuming that I want the test light to illuminate once the 5 degree mark on the crank pulley is lined up with the case seam, while rotating the engine clockwise (by hand)?. The CRIP angle in the ECU was adjusted until commanded ignition timing was the same as actual ignition timing. You can even use it to check timing on electronic, conventional or computer-controlled systems. Pull your fuel pump relay use a timing light and. That’s it! Don’t forget to tighten up your distributor clamp bolt. Re: Ignition Timing Q. Set up your dwell meter and hook up a remote starter. On world models, idle speed is 950-1050 RPM. And at this point you need it fixed. to set your base timing without a light, you just turn the motor over in it's normal direction of rotation until the mark lines up with where you want it. The strobe timing light is then shone onto the ignition timing measuring plate 100 and the rotating indicator pointer 106. The cam also plays a big part in the equation. Check the timing. Range of adjustment - 30° at crankshaft. Rotate dist clockwise for timing advance, turn till highest speed, rotate back till it slows to min speed then back till it barely speeds up. Set engine speed by turning idle adjustment screw clockwise to increase speed or counterclockwise to decrease speed. If this happens set timing to 15 degrees, allow the engine to fully warm up, then disconnect the set timing connector to set the base timing to the. How to Set the Dwell. We have to divide by two because our wasted spark ignition system fires the spark plug every revolution instead once every other revolution. Ignition Timing Without A Light/gun - posted in Problems, Questions and Technical: I have a 81 leyland 998cc that has been running below average of late. The Performance Tool W80578 Self-Powered Timing Light is designed for all gas engines, outdoor power equipment, motorcycle, snow mobile, mowers and tractors, works with magnetos. Place tranny in neutral. Its an arduous process of playing with the timing and test driving the car listening for detonation. Now point the timing light at the engine's front cover and observe the mark. To set the timing on that engine, have the s/plugs out, and have the throttle at full, set that timer base under the flywheel tight against the rubber stop on the end of the full spark timer advance stop screw (wire it against that stop if necessary). I put the strobe timing light on but I didn't know whether to set the timing with the vac advance pipe removed or not?. Place a straight edge ruler across the bore. Hook up the timing light to the #1 plug wire. Remove your timing cover, RH side of engine on gear cover. But currently- my idle spark at at notch 11. I have a video "how to set ignition timing in your car" and it is really simple to do. Now I could set it up using the static method if it had points, or using a timing light if it had the inspection plate/x cap. The sequence in which this happens is very finely balanced, or "tuned," to provide maximum power and economy. When in the base timing mode, a conventional timing light can be used to measure ignition. Or whatever advance your engine can hold without knocking. I'd seriously consider buying this bracket if it' s missing - you'll want a timing belt cover one of these days, and not having a cam timing mark is going to be a real pain. piece of copper wire to jumper (short together) terminals T and E1. In this case, the engine is idling at 17 degrees of initial timing at 781 rpm. The engine speed to check at typically indicates where there is a 'knee' in the advance curve, e. So open that hood and let's get started. Manit ran awsome after he played with it. The car is running well but speaking to an e-type mechanic the other day he warned me that the 123 distributor should be on setting 0 (zero) as any other setting would be too advance and cause the cylinder heads to. It's different from ignition timing,it's got to do with when your valves are opening and closing. Once all this is set, theoretically, when the points are worn out, you should be able to replace the points with a new set, set the gap and all will be correctly timed. Timing strobe light. When I pulled the thing apart, the ignition was set with the plate at full clockwise. These diagrams include: Fig. That should get you close enough until you can get to a timing light. Now set the Centrifugal timing. Should be easy to set the timing at the F marks and then check the advancer is hitting the || full advance marks with a strobe. I followed these procedures: 1. Posted 6 Feb 2014 07:21. The sequence in which this happens is very finely balanced, or "tuned," to provide maximum power and economy. I start the engine and let it run until it's warmed up. It is recommended to set a 10 degree advance offset for the Chevy HEI 8-pin system. If you see +5V, then you're at TDC for the rear cylinder -- rotate the wheel until you see the mark again. It is simple. question is about timing. 0s is a time-honored trick to wake up the under-hood lump. to set the timing with the engine running there is a TAN and black stripe wire. Jan 24, 2016. But I doubt it without some major modifications to do it. This is important because a number of high-end timing lights say they work with electronic, computer-controlled, and distributorless ignition systems (DIS), but that’s a little misleading. There is a mark or notch on the distributor housing that the rotor should be pointing to when the e. He said the dual diaphram 68 dist was not the one to use. I'm timing a pretty stock 454 with non hei distributor, but it's kinda a general question as well. Best power is achieved when ignition timing is set to fire the spark ahead of time to reach that peak pressure at about 2 degrees after TDC. Doesn't work in my humble opinion and will have you way way advanced. The only way to know what you you are doing is to first establish an accurate TDC mark. It may kick back a little due to the advance coming in immediately without the springs. When the oil has a lot of impurities, it loses viscosity. The purpose of engine timing To make sure the spark in each cylinder, occurs at the right instant for most efficient ignition of the petrol engine. Ignition timing is like seasoning: some is good, but too much ruins the results. Locking the timing out is used to verify that the timing the ECU is commanding is actually what’s happening at the engine. 8:1 and an ev27 cam. If you have a timing light you can use it to set your timing. The ignition timing is adjusted with the slotted screw/pot in between the two extremes. In the version 1. Dooley, Apr 3, 2008. The speed of the timing curve is determined by the springs on your advance weights inside the distributor. Adjust the 13mm clamping bolt shown earlier so the dizzy can just be twisted by hand, but not so loose it turns too easily, because of engine vibrations. , this advances your timing. I went to do a test drive, but couldn't pull away. If the best timing for power coincided with the same timing for minimum emission, or if the engine were going to run at some constant rpm, the timing problem would be simple. Remove spark plugs. there is an angle scale near top of pulley. Loosen the distributor lockdown bolt with your wrench. The uses of the EETL500 are highlighted in detail below: • Setting ignition timing - works on both 2 & 4 Cycle DIS and conventional engines and most. How to Set Ignition Timing -- 1 of 1 Heres a step-by-step on how I set the initial ignition timing. Tennessee, United States. In this case, the engine is idling at 17 degrees of initial timing at 781 rpm. The new timing device not only features a diamond plate underside and large backlight LCD screen, it also. where the weak spring taps out and the hard spring kicks in. Re: Ignition Timing Yeah that is the problem, I don't know how to determine 0 tdc without pulling the plug and checking but would that be accurate enough to sufficeor I could buy another timing chain cover with the timing tab for reference and I guess even cut it off the new one and glue it to the old one, I dont want to have to pull the current one off if I can avoid it. My question is, is there a standard how ignition advance is. There is a built in red light that you use to set timing. Write this number down. " Since disconnecting the plug wire from cylinder 1A is difficult, disconnect the wire from the distributor cap instead; make a small jumper from an old ignition wire to use to connect the timing light. Save Share. Without it, you set the ignition to fire somewhere between 27 and 30 degrees before top dead center. Make sure you are rotating the engine in the same direction that the starter motor turns it. Just can't be done. Make sure your mechanical timing is correct first. Then use the clips to connect to the battery. Will a car start if timing is off? Ignition timing is the setting of the spark plugs to ignite when there is a compression stroke. Make sure the parking brake is set. Timing dynamically is fairly simple and is the best way to time your engine. Even if the bulb did not work, it would have no bearing on adjusting the timing. The timing light has three leads. then you all sorted Without Vag , you wont be able to stablise the idle. Electronic ignition is the single best modification to carry out on an old Jaguar; it transforms the spark voltage, eliminates timing errors at high revs, and dramatically improves fuel. bust out timing light. The ignition timing is not adjusted with a timing light or with the engine running, and to set the ignition timing follow these procedures. Finally I got the timing spot on. It can also be used when installing a new distributor. I recently fitted a 123 electronic distributor and set the unit to advance no. By this stage, you have a rough timing but don't try to start it this way. (DBTDC) Your ignition will fire at that point regardless of the rpm the engine is running. Many factors such as engine temperature, load, RPM, fuel ratio, etc. Once the motor is back together, connect your timing light to the HT lead and to a battery. Now; to find and set the total timing all you need to do is set the dial on your timing light to 36. This can be done with our professional quality timing light. You don't want to be hunting for them later while. , since it is a wasted spark system firing every time the crank goes around). I was wondering if anyone has ever set their ignition timing without using a timing light. Looking about right, this is open. You could advance it, say, 12-degrees beyond stock for a false reference signal of 12-degrees BTDC instead of zero degrees or TDC. Typically timing is set with a timing light. Rotate dist clockwise for timing advance, turn till highest speed, rotate back till it slows to min speed then back till it barely speeds up. Ok, from what I understand about how to set up engine timing, you first have to have the engine at Top-Dead-Center on the compression stroke. After about thirty minutes when I stop and then go at a light, there is a slight hesitation and then bam, off like a rocket! I set the timing at T. The timing light input lead should always be attached to the No. Then use the clips to connect to the battery. Curb idle speed: 700 f 100 rpm NOTE The engine speed indicated is a third of actual speed. Connect the vacuum hose to the vacuum control unit. If you are provided with different timing set points and don't have a computerize ignition system, you should set your timing to Total Advance or at the highest RPM spec you are provided. Connect a timing light to No. " Just because you can set the timing statically close enough to get it running doesn't mean it is close enough to hit the byways. Some adjusting and checking. Set the timing to 8 degrees BTDC. " Since disconnecting the plug wire from cylinder 1A is difficult, disconnect the wire from the distributor cap instead; make a small jumper from an old ignition wire to use to connect the timing light. The electronic timing (advance or retard) must be less than + or - '2' or the Check Engine Light in turned on. Have someone idle the car to 3000-3500 rpms, look at the timing scale again and turn advance knob until the line on the balancer is at zero. Ignition Timing. yeah you just need to tell the ecu that you are setting the timing via vag. It is easy to see with the cap off. Connect a timing light to the engine and check the ignition timing. Remove the vacuum hose from the distributor advance unit. The function of the advance curve is to match the ignition timing to the burning rate of the fuel and speed (rpm) of the engine. I agree with Ignition Man, I have used his advice on several occasions and found that his approach to ignition timing is spot on. , just ticking over (700-800 RPM). Re: 720 ignition timing, new SBT motor. When the timing marks just start to appear, a 12v test light (or a multi-meter set to 12 volts DC) should be connected across the contact points (one side to ground, one to the hot lead on the other side of the points). Set both the Base Timing and Initial Advance on MegaSquirt-II to 5°. Keep in mind when adjusting the timing, you have to turn the distributor clockwise to advance and counter-clockwise to retard. Dizzy-equipped M30s generally have the ignition timing dynamically checked at ~2000-2200rpm. Carefully done, it's rather accurate, easily within one or two degrees. Hey, I read that advancing ignition timing to 14 degrees BTDC would give me a slight power boost so I tried it out today. If you recently have replaced the distributor in your car or plan on doing so, prepare to set the ignition timing in your car. I even suspect my timing light!. Suddently, the timing marks for TDC and 5ATDC disappeared, as did the ones for 30 and 35BTDC, and my digital timing light was indicating 60 degrees of advance. The converse thought -harbored by the less-trusting- is that using a timing light requires all of the markings to be indexed precisely to be valid. Just for fun I also checked the timing with a strobe light. Manit ran awsome after he played with it. piece of copper wire to jumper (short together) terminals T and E1. Place tranny in neutral. When I set the timing by attaching the pickup for the light to the 1st coil pack, and the MAF is plugged in, car warmed up, the signal is somewhat jumpy, but when i adjust it to 15* on the crank, the CAS is maxed out almost all the way advanced (no gap between the CAS adjustmetn and where it bolts to it, its maxed all the way out almost). If there is no timing advance using a timing light, check the Pink (PK) wire at the ICM connection for a square-wave signal as the engine is running using a labscope. Ignition timing should indicate 10 degrees BTDC with the SPOUT connector removed but timing should then advance when the connector is plugged back in.
