Ok guys/gals, here goes: I have a 2000 zx3 5-speed, My ECU crapped out right before I deployed to Iraq due to an improper winshield install which allowed water to trickle down into my fuse boxNow the dealership said it was in need of a new ecu. Ok a junk yard offered me a 5-speed ecu with matching cluster. The Prob, will an ecu from a different year and code work on my focus? What about the P.A.T.S.? Will I need new keys or re chipped keys for a new ecu? PLEASE HELP! THANX!
