computer ?

[#17cmc]

where there any changes in the computer from 89-93 to 94-95 and if so can you run a 89-93 computer on a 94-95 intake and throttle body

Yes there were changes, it takes tuning to swap them, I fouled 2 plugs when I swapped mine in a 95, ran way too rich. I've heard of people running them and liking them much better, something about it keeping the timing up when shifting.

Someone have more knowledge on this?

As USMC302 said there is a difference....are you referring to the tip-in retard USMC?

IMHO I would save yourself the hassle and just have a chip done if you are have problems. The T4M0 really isn't user friendly with mod's without a good calibration. We have done a few with blowers that are running REAL well, so the stock box can be adapted to your need's.

yes you can, I have heard many guys doing this. The Fuel curves and timing is alot better on the 89-93 computers rather than the 94-95's. Reason = emmisions. Not sure exactly what you have to do if anything, but it is possible.
