Anybody ever use one of these things? I found one at summitracing.com and they don't give much information about it. I would like to find if anybody has used it on any of their vehicles, not just a Neon. I have a Pontiac Grand Am that could use a little help in the horsepower department also, but I would like to keep it close to stock and if this thing works I think that it would be the way to go for me. Thanks.

 

wont work on the Neon...

 

Why not?

 

not quite sure why...i think it has something to do with the fact that no one except Modern Performance and Mopar has been able to crack the circuitry on the PCMs...

 

And howell automotive

 

basically you have 2 choices, A Mopar Performance Computer or an AF/X?

 

The stock ECU is not reprogrammable. Thats why it wont work.
