will a pcm out of a late fox work in 94 gt? if so does it plug right in as long as its from a 5.0 5speed car? my stock pcm just come up prom error code everytime i scan it, my car has a dss 306 trick flow heads and intake, also a stage 2 cam, thanks guys, much is appricated to get it running right.
No go on the plugin - I'd find a 94/95 PCM off eBay. You don't happen to have a chip on it eh? That'll throw a checksum error if not turned off. Wes
They do not suck in general....just with the stock programming. It is a far better processor/computer compared to the fox A9 family. It is like comparing a 386 to a pentium3 or 4. Get a tune or tuner on the eec by either learning how it works or from someone who knows the eec (like wes the guy who posted above you) and you will be better off than with a A9 that will still need a tune to get the most out of your combo.
Those 94-95 pcm gotta suck I mean .............. You can find all kinds of stuff written about it all over the net Those old wives tales will never die If one could get a fox pcm to make great power with NO ISSUES what so ever and A set of 355's which will turn way less rpm on the highway than 373's as well as Get way more gas milage than 373's and Then make sure when they do up a stroker They do a 331 instead of a 347 so they don't have the oil issue thing as well as The 331 will not have a short life like you have with a 347 Well ... If a fellow could wrap all that good stuff up in his 94-95 Stang He would be all set ... Now ... Wouldn't He Honestly 5literstang Sounds like you've been listening to or Hanging around peeps who TALK about it If you go and hang around some peeps who have DONE it You are gonna get a very different story :Word: The pcm in the 94-95 GT and Cobra can be made to operate just fine like Greg has said above btw ........... Greg knows his way around a 94-95 pcm and He would be one of those peeps I talked about who has ... DONE ... it Grady
i already have a tune, with a chip...my computer is doesnt allow me to scan, i just wanna know if a 92-93 pcm will work cuz i can get one for nothing, sorry about not posting about that before, my bad guys
Have you tried reseating the chip? If it's not seated properly, or the contacts have corroded, you'll have issues galore. If you remove the chip, are you able to pull codes?
chip is probably still ok , sounds like the PCM took a crap , id find a used one on ebay , or call MPSautosalvage.com , they usually keep them in stock and will guarantee you get a good one
