    With Key??? I've got a LTD ECM, Lanyard would be extra, but lanyards don't usually get damaged from corrosion, why can't you reprogram yours to the new ECM??

    you DON'T need a 03 ECU!!!!
    the 03 ecu for the 185 has a 7650RPM limiter.............

    the 04-05 RXP-RXT ecu will work ALOT better. it has a more agressive fuel curve and a 8100 limiter. It will bolt and plug right in, everything will work perfect. We are running a 05 RXP ECU on the 03 185 motor in the SUV. noticed a imediate increase in rpm and acceleration.

    I think it's an 05 LTD which would be 215hp, hours as far as I can remember were somewhat low I think around 60? I'll have to plug it in and check. I can also get you a lanyard(s) regular and or learning.

    you may want to upgrade to the 58 psi fuel reg too. stock one used on a rxp or rxt.. (185hp has the 44psi reg) plugs right in

    Thanks for that. Now i need a ecu from a rxp or gtx ltd with 100+ hours(trying to keep the same as mine) with a lanyard and an fuel regulator. if anyone can help would be great.
