Non-Start Diagnosis
When the engine is cranking/running, take note of the Injector Duty, as well as the position of the yellow cross-hairs on the Base VE Table - this is the VE number the ECU is looking at to compute the final injection pulsewidth. To add fuel, increase the number (Press W on the cell), to reduce fuel, reduce the number (Press Q on the cell), and so forth.
Engine Coughs, Kicks back during cranking
This is an ignition timing issue. Most engines will start and run at around 10-20* of advance. Check the angle you are seeing in the Ignition Adv Angle DRO, and adjust the Ignition Table Pri1 table as required. Also be sure to check ignition lead order, as well as base timing.
Engine Runs but Cuts out shortly After starting
This is usually down to fuel starvation - check the fuel rail is remaining pressurised during running (i.e the fuel pump is staying active), or, force a richer mixture by increasing the VE numbers at the cells where the cross hairs are during initial startup/running.
Engine Fails to Fire/Pop/Bang AT ALL
Check the spark plugs - if they are soaking wet with fuel (too much fuel), replace/clean, and reduce the VE tables numbers by 30-40% (Select the entire table, press the ‘=’ key and in the box that appears, type -30% ), retest. If however, the plugs are bone dry (not enough fuel) check for fuel pressure, injector operation (clicking under test mode), and try increasing the entire VE table by 30-40%.
If you still cannot get the engine to start, please record a log (see the MEITE manual on data logging) and email it to us, along with your calibration, to support@motorsport-electronics.co.uk.
