    04-05 is the only one that will work,youll need to stick an ECU that is the same year as your motor and electronics..And Yes an RXT one will work...

    If you go with an RXT ecu... you'll need to get the trim function turned on with BUDS, and have the TPS re-set while your at it. But yes... 04 or 05 RXP-RXT ecu will work.

    You have to find an ECU with 664947 code on it!
    It does not matter if it is RXP-RXT!

    Ok found a ECU on eBay for a 04 RXP but reads part number 664942. Will this work for my 05? Will I have to program anything else?

    Im guessing this will be done @ the dealer. BUDS?? Is that a system the dealer uses?
