    ecu compatability

    Guest-only advertisement. Register or Log In now!
    got an APR chipped ECU, that ECU part number ends in 558M, I opened mine to find it's a 557P (like I thought).

    Are they still compatible? I'd like to install tomorrow if possible...

    Thanks guys.

    Did a little research for ya from what I found out it will work. The 558M box is a rare 97-99.5 non-dbw ECU and is compatable with 557P box car's you just need to adjust your softcoding if it came form a car with different option's
