Ecu?
 

Yeah, Yeah, Yeah.. i'm a n00b.. lol. but what is an ECU.. ? i feel stupid asking the question, b/c it probably has been posted before.. but how much would a new one cost me? is the ECU the wiring harness for the car? well.. i need a few things for my car... mainly a new wiring harness (pretty much for the whole damned car) and i need the fuse box under the hood.. mine's screwin up w/ the wires and shit.. any suggestions?

The Ecu is the computer.......it's located on the floor behind the radio deck.........as far as I can remember...........

ahh, ok.. what should i replace my stock ecu with for max performance w/ best efficiency? also, how much would it cost for a new wiring harness?

Is the ecu the same as as Escort gt ecu? I have a egt I wrecked and thinking of getting a protege w/ the DOHC so I could have a spare engine but I had the ecu reprogrammed and want to know if i could exchange them.

The ECU for the DOHC and SOHC motors are not the same and are not interchangable.

the protege also came with the dohc engine, will they intechange with the same engine family?

The ECU for the Escort GT (91-95) and Protege LX (90-94) are interchangeable. They're same car essentially, just different body panels. The SOHC and DOHC ECU's are not interchangable with one another.

great! thanks!
