i have an 88 mustang 5.0, i want to do away with the speed density system. i happened upon a wrecked 93 5.0 and grabbed the ecu and mass air meter out of it, and the wiring kit is in the mail. question: the ecu is marked c3w, will it work in my car? the donor car was automatic and my car is standard. ive read alot of threads on a9l and a9p ecu's but havent heard much of this c3w. your help is much appreciated!
