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?

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
