I recently bought my car and wanted to get into it and (stupidly) reset the apexi ecu without knowing how to retune it for the injectors the previous owner had in the car and am now stuck as the car has 1000cc primary injectors and 1700cc secondary injectors as I can't drive the car with it dumping the amount of fuel it is into the engine. Is there a way to fix this easily with the fc commander?

welcome to the board.

i do not know what to tell you, but i can refer you to the subforum that might have some helpful answers.

have you identified a tuner yet? just keep in mind that at the end of the day, the safest thing may just be to tow it to your tuner.

Talk to banzai racing and see if they can provide you a base map for your setup. Might as well throw them some dollar bills for the support.


I bought a patch harness from banzai to use a fd3s power fc, and they gave me a good base map based on my injector sizing.

And buy a datalogit, download the fc-edit software. The commander is pretty much useless for what you’re trying to achieve. Fc-edit gives you full access to setting up the power fc, plus you can datalog with it and trap afr’s.

Ok thank you I’ll look into contacting them before I tow my car because I think the closest tuner is about 300 miles away
