ECU QUESTION?

[Whitepony]

okay, so apparently the 98 gt has more power because the ecu is a little different?

i have a 97 gt, can i swap my ecu for a 98 ecu and gain power?

and also can could i use a diablo tuner with a 98 ecu? i would love any information!

I say just get your 97 ECU tuned for around the same price as the 98 ECU and you will gain more power. But from what I have heard it can work to use the 98 ECU in your car! Too much work IMO

im gonna go with a no on this because the 98 has a different fuel system than a 97....

ahh gotcha, its fuel mapping wont be right on a 97.

ill wait untill i do more mods then get a tuner. i dont really have a need for one right now its still fun to drive!

Simple answer: NO you cannot use a 98 ECU in anything but a 98 car

Complicated: You probably could, but the labor and complete rewiring of the car would make you an idiot for even trying it.

Different fuel system is just one of the issues.

From HERE both regarding a guy wanting to use a 98 ECU in his 97 GT.

as I answered in another forum, a 1998 ECM WILL NOT WORK in a 1996 or 1997 GT, total BS whoever told you that.

1998 fuel system is not only different then 1996/97 but is also wired differently in the PCM and harness, it could be done but Major rewiring of the harness would be required and I sea NO gain by doing this. stay wth a 1996/97 GGL4 PCM and you'll be fine

and

YOUR TUNER thinks you should use a 98 PCM... Does this guy work on fords often????? it won't work the 98's have a returnless fuel system.

He must be really confused.
