What def. file is needed in Tunercat to read Vortec TPI 4.3 PROM?
A friend of mine has a 93 S-10 with a Vortec TPI 4.3 L V6. He ordered a Jet Chip for it but they didn't take out the speed limiter in the PROM. Will tunercat read his PROM and if so, what def. file is needed to do that?
Thanks,
Mike

I was gonna say that I knew it, but you should check with the aforementioned website first. If your engine is indeed the CPI engine (not the throttle body) and you wind up with the $0D definition file (ECM 16196395 or 16197427) then I might be able to help you out with any and all questions. I have spent the past several months tweaking & playing with that one.
