Hi David, thanks for the response. I was made aware of this before I configured the ECU so it should be all good.
IGN1 - Cyl 1 ; IGN2 - Cyl 5 ; IGN3 - Cyl 3 ; IGN4 - Cyl 6 ; IGN5 - Cyl 2 ; IGN6 - Cyl 4. Injectors are same.
I've literally JUST been out at the car to test injector and ignition outputs. Found an anomally.....
Went into the ECU to the test IGN output page. Removed No.1 coil and fitted a test plug and earthed the plug. On starting test,
nothing happened...
Then went into PDM to check all was well there. On the PDM monitor page, the coil output pin had tripped out. On resetting the fault I tested the PDM coil output, only when the coil load reached 100% did I notice the spark plug physically fire!! It then tripped out!! I have
not got this output to 'always retry'.
I have the PDM set up so a common coil +12V is supplied from a 20A output (Output 7). I am using R34 coils with built-in igniters. The coil +12V pin is set to be active when the ECU output pin is active (which made sense). Config below......
Firstly, I was surprised that the coil fired without a 'fire' command to the coil from ECU even though +12V was being supplied.
Secondly, this sounds like more than just a current under-supply problem?? I have another free 20A output so could easily add another 20A to the circuit. However, the PDM manual does state that ignition systems don't normally require more than 1 20A output..
Glad I seem to have traced the issue to the ignition but I can't figure out what's wrong here...
TT
