I have just hooked up my microtech and in teh midst of trying to get my abomination running, The trailing plugs were firing last season with stock ecu. I have ignition switched power to both brown wires of the trailing coil I have the tach hooked up to the yellow wire and the the microtech lt8 two trailing wires hooked up to the correct wires. Im kinda stuck right now. the leading plugs will fire and the car will kinda start but just totally stumble and die.



is there something in the microtech that could be causing this? did the coils spontaneously implode itself?







Also to note i have been wondering about this to, I dont know if anyone here will be able to enlighten me on this but its worth a shot:



I recently purchased a harness off of someone who said it was off there last car. the harness is wired for my LT8 ecu but I have noticed a couple pins/wires on the harness are missing compared to the ECU diagram pinout for the LT8, I have attached an image of the diagram with a red X showing which wire/pin I am missing on my harness and wondering how crucial this is. I am experiencing no spark coming from my trailing coils and am curious if this could be related to that.
