:lol: what does no chip mean? either way, you still have a chip plugged in, and it still stays if you want the tune.
the TwEECer and Quarterhorse are just more powerful chips.
the best way to do it that i could come up with was TwEECer RT or Quartehorse and tune til the car runs great,
then export and burn a chip with SCT Pro Racer so you can use the TwEECer elsewhere.
you don't want it tied down to one car. expensive, but you pay to play.
tuning is not cheap. people wonder why a tune is expensive? there is a reason.
the cheaper option is straight to Pro Racer and datalog, tune, datalog, tune, repeat til the car runs good. you don't have realtime benefits of the RT or QH, but its doable.
i haven't got my TwEECer RT to work with my 93 yet. i was going to get a different computer to try, as the 94 or 95 computers are supposed to be supported.
worked brilliantly on our 89 SHO though. its fun to watch CalCon and CalEdit do there thing.
allegedly with the quarterhorse, you can pull anything you need right off the computer with the software that runs it. binary editor i believe.
