So, after months and months of VATS trouble, I finally found that the VATS bypass can be a two part job. In my casebypassing the PROM in the ECU wasn't enough - I had to permanently enable the crank enable relay.

I'm proud to say my car runs perfectly now (for a 16 year old car).

There is, however, one new problem. The bypass we were sent came with a 110mph speed limiter which we didn't order. Rather than send it back and wait for a replacement, a friend of mine with his own camaro suggested I get an entirely new performance ECU. He promised me the usual "noticeable difference."

What do you guys think? Has anyone come accross a chip that actually increases performance in a stock camaro?


1992 Z28 305 w/manual.

Thanks!

 

Some chips on a stock motor just change minor items and really don't add performance,but they do make a small difference. Just don't expect a 305 tbi to turn into a fire breathing 350.

 

not ona stock car, and then even if you are doing it to a very modified car you are playing russian roulette with ur motor.you dont know if that tune is good for you. strap that car on a dyno for basically the same cost as any of these chips.

i personally dont trust mail order stuff, i like to see the AFR curves for myself

 

I guess there really are no free lunches.

 

you can find a free lunch in any dumpster you see.
its where most of them "performance" chips end up maybe you can find one of them too.

 

Yeah, those chips don't do much good at all, if any.
