Chips ended in f-bodies in 92, so you need programming. To do it your self, you need a laptop, software, and a cable. Software can be free (Tunerpro), or bought (LT1 Edit, Tunercat, etc.). Need definition file (EE, also free). Better read and learn a lot before going this route. I can give you a copy of the factory tune and the EE definition file. You can download Tunerpro, just google Tunerpro.

Can buy a “mail order” tune. Look up madz28, or pcmforless. Both are pretty well known for LT1 tunes. I had a madz28 tune in my 94 ta, was pretty good.

Take the car to a tuner with a dyno (dyno tune). Best route, but most expensive. make sure they are using a wide band o2.

Ive done some research, need to retune mine, but dont want to screw it up. Theres tons of files out there that other have from their car, tons of combos, find one close and go from there. Ive been waiting til I install headers before going any further. Mines a 94 also, so you figure it out and you can do mine then lol!

you are obd I so it’s going to be real easy. Just buy an aldl cable ($60) or make your own (~20). get teh flash version of tunercat (i think that’s about ~20) and find a definition file online… and you will have limitless tuning abilities.

Does this work for others too, or just the LT1?

not going to laugh… ok maybe i am… lol…

but any hoo… I am not positive if the software will load those particular definition files… I don’t have my laptop so I can’t check… but anyways… you won’t be able to find a free definition file online because there isn’t a big market for 3.4L engines. Your best bet would be going to [pcmforless.com](http://pcmforless.com) and talking with bryan or alvin there.

TunerPro FTW

I mean, it’s free!

If you have a laptop just pickup an ALDL cable, download TunerPro, and do a lot of reading…

Yep, TunerPro RT, and an aldl cable is the best way to go. LOTS of reading.

Read this: [http://www.thirdgen.org/promintro](http://www.thirdgen.org/promintro) it’s one of the best descrpitions of how to jump into “tuning”. Please note that it is related to 3rd gens, so you do not need all of the “prom burning” crap. Start at the section labeled “Modifying the BIN”, thats the stuff you need to know.
