I have an A-spec HH, 5810 ECU was faulty and wouldn't start car. I got my hands on a 5808 ECU. Has anyone swapped these before. I'm aware that it's a RS ECU and therefore requires 510cc injectors. I need info on wiring/pin changes. Do I need to swap 6 & 14? What about ABS & Fuel Pump signal wiring changes? Seeking help as this ECU is in excellent condition and I don't want to damage it. Any help will be appreciated.

Thanks, after looking at that I gather I don't have to swap 6 & 14. Install 510cc injectors, swap ABS (11Aus to 13 J-Spec). Any idea what to do with fuel pump drive signal?

I'd be inclined to leave it and see if the fuel pump runs as it should. If it does good, if not then I'd jump 13 to 56.

Swapped ABS pins, left fuel pump signal pin disconnected. Fired up ok, seems fine without it. Thanks for your help. I can run in my motor and clutch now. /ubbthreads/images/graemlins/laugh.gif
