    swap 04 RXP ECU with 09 RXT X ECU

    I did a search on this but I couldn't find the information. I would like to install a 09 RXTX ECU, 42 injectors and X charger in a 2004 RXP . Has anybody done this? Will this work? What else will I need ? Jim

    I think your gonna need the entire electrical harness, fuel tank/pump assy, and dash cluster as well.

    Only 04-05 ECU's are compatable with the 04 electronics.

    You will need X harness and cluster.

    Get the Xcharger and a used ecu for 04-05 ski like Riva or les and You are good to go!
