Hello, I have an '89 Swift GTi with a IHI RH5B turbo. I just installed a AEM FI/C 6, I wired it completely in and I am unable to start the car with the FIC plugged in. I have been using the Suzuki Swift GTi Service Manual to base my wiring information off of. When I have the jumper cable plugged in the car starts and runs fine. I wired the fic injector inputs to ECU pin C8 and C9 the "injector negative". Then the fic injector outputs 1-4 go to each of the injectors (injector 1 out to inj 1, injector 2 out to inj 2 and so on). I really need help; I have been back and forth with Ed and Henry at the AEM Tech support line. We have been unable to get a injector wiring setup to work. Any help or any experience with the AEM FI/C and a Suzuki Swift GTi would be greatly appreciated.
Thank you

AFAIK you cannot use the FIC with low impedance injectors. the stock ECU uses PWM to limit current. are they aware that the swift uses PWM at AEM tech? I could be wrong but I'm pretty sure you can't use a FIC with PWM because it needs a clean pulse width to read the injection time and alter it

i have replaced my injectors with high impadence injectors from RC Engineering (310cc). After talking with the guys at AEM i had tried different wiring configurations with the ECU and FIC. but after a little thought and conversation i am woundering if i add a seporate 12v power supplie to the injectors and then wire the injector negative from the ECU to the FIC then injectors. i am hoping that this may allow the FIC to controll the fueling and help me achive the AFR's i need. Any insight or information on this would be greatly appriciated.
thank you

that is exactly how it's supposed to be wired :huh: you don't need a separate 12V, you need to intercept the injector grounds. even then I don't think it'll ever work right.
