Full milspec harness, continuity checked, still not getting signal to the m&w from ecu. Going to bench fire the ecu today and test it with a oscope. I will know today if the coil driver is dead. I assume it isnt a common deal, maybe just got a bad box.

I will update tomorrow on status. The car was seeing RPM, Cam, and Crank signal.... it wasnt syncing and it was showing weird timing errors that were not normal vs the day before when it was running. I am HOPING it was something stupid as we just removed all factory wiring and did a full milspec chassis and engine harness. If I have the same problem I will update with a file and logs of cranking along with a video of the runtime values.

The problem that I saw was that the ECU registered cam and crank signal... I could test the injectors... but it wouldnt let me test the coils.... it wouldnt send spark at all

Thursday afternoon I got my evo 8 drag car to fire up and run/idle on the new fuel system, probably started it about 10 times, made some changes to the fueling then called it a night. Woke up Friday to get everything else finished on the car to get it ready for an event. Once we were all done, tried to fire it up and it wouldn't fire at all.... tried testing the injectors... all testing fine being able to hear them cycle, coils-nothing. The coils didn't cycle or anything. Timing errors which are usually 1..... were double digits however it registered both crank and cam sensors. Anyone have any input or experience? I'm worried that the ECU dropped the coil drivers, I tried two different ignition systems and they didn't work. The M&W box didn't register any signal being sent to it. I am absolutely stumped and want to get this fixed before my next event (May 7th) .

I appreciate the file, I looked at it and still have a few questions. The OEM harness has 3 MFI relay pins. (2 inputs (12v switched) , and 1 output) Where should these be configured in the ecu? Currently I am not getting power to the MFI relay which sends signal to the injectors and coils.

I am going to use the oem harness with a patch harness to get the inputs and outputs right before I complete a fill mil-spec harness but there is no support here in the U.S for me to ask questions relating to this vehicle and the ecu interface. I am running 8 injectors, wasted spark(for now), 12 tooth crank trigger, 1 tooth cam trigger, factory TPS, Speed density (5 Bar MAP, AIT), Wideband, push button start, electronic boost controller (MAC Valve) If someone could provide me assistance in getting these set up to their appropriate pins I would greatly appreciate it, I have them mapped out in my book but want to ensure that they are in the right locations needed.
