Ok ok, before you flame me, I have read the Power FC FAQs. This is an Apexi Power FC D-Jetro for and RB26/30 in an S14. Engine starts and idles fine with the stock ECU, plug in the Power FC, and it just starts and immediately dies. I have turned the boost control feature off. I am using 1000cc injectors and have set the injectors to 44%. I am using the GM 3 bar map sensors, which have not been calibrated in the hand controller because apparently I need a dataloggit. I have the signal wires of the map sensors going into pins 27 (black wire) and 35 (orange wire). I have checked all power and ground connections, all are ok. Anyone have any incite into this? Would be greatly appreciated.
