Calibrating Ignition Timing


00:00 - Once the trigger setup has been set, the ECU should be getting relevant information about engine RPM and engine position.
00:07 We still need to calibrate the ignition timing and this is one of the most critical jobs when setting up your ECU.
00:14 Calibrating the ignition timing aligns the ignition angle that is displayed on the laptop with the actual ignition timing the engine is receiving.
00:22 To do this, you need to be able to start the engine and run it.
00:26 Once the engine is idling, press the escape key to access the ECU settings menu and click on triggers and then calibrate.
00:34 Double click on set base timing and a window will open.
00:37 At the top of this window is the ignition angle that the ECU will lock the ignition timing to.
00:44 This means the ECU will ignore the ignition tables and any compensations and simply supply a fixed ignition angle.
00:51 Choose an angle that is easily visible on the crank pulley with your timing light.
00:55 Once you've chosen an ignition angle you can check the actual ignition timing with a timing light.
01:03 If the timing you are seeing with the timing light doesn't match the locked angle.
01:06 adjust the offset until the timing is perfect.
01:22 The last step is to adjust the ignition delay which helps to keep the ignition timing stable as RPM increases.
01:29 Start with the ignition delay set to zero and increase the engine RPM to around half of the rev limit.
01:35 Watch the ignition timing and you may see the ignition retard slightly.
01:39 Increase the ignition delay until the ignition stays stable regardless of RPM.
01:45 Once the timing is stable, click done and store the changes by pressing F4.
01:50 If you are calibrating the timing with a custom trigger setup, you may be starting with the calibration too far away to allow the engine to start.
01:58 In this case, you can disable the fuel injection by opening the ECU settings menu, heading to the fuel main menu and under injection mode, select off and press F4 to store the change.
02:11 You can now crank the engine and it won't start.
02:14 View the timing with a timing light while a helper cranks the engine.
02:18 You can make coarse adjustments to the timing offset until you are close to the correct timing angle.
02:24 Once you've done this, enable the fuel injection again, store the change and you should be able to get the engine running.
