I recently bought a laptop and was wondering, what is the best software to tune the LT1's. I have a 96 but I've converted to OBD1.

Thanx in advance

Tunercat is probably the cheapest and works as good as any, AFAIK.

Ditto TunerCat. It's cheap, works on unlimited PCMs, and if you ever get to the point where you can find new tables, you can add them yourself with their definition file editor!

Zac2003, if you have an OBDI LT1 PCM ('94/'95), with an OBDII connector (16-pin), then yes, TunerCat will work. It's what I use!

JSK, I have a 95 so I believe I do, how can I tell if my pcm is obd1 or 2?

TunerCAT rocks harder than montley crue... Maybe someday I'll get the RT version (just need the romulator). I use TunerCAT and it is a great program.

Yours is definately an OBDI computer, most likely with a OBDII port. Buy Tunercat and an OBD II Cable and you should be fine. Some of the earlier 95 models do have an OBDI Port.

whats the difference between the rt and the regular??

http://www.tunercat.com/tnr_desc/tnr_desc.html thats the correct link for the tuner I need right??

also if the rt is worth the 30$ I'll go ahead and get it.

what about us obdII guys?? and whats all involved in switching to obd I??

Zac2003

not sure maybe just need an obd1 pcm ??? what other differences are there

OBD1 pcm and also the obd1 knock sensor which screws into the coolant passage on pass side of block. Thats it!

so my opti crap will line up?? and the whole wireing harness?? so probably need to find a 95 pcm then or will any work??

Your wiring harness, opti, all that jazz stays the same. Just plug in the obd1 computer and obd1 knock sensor and you are ready to tune.

does the pcm have to from another 6speed car??? sorry for all the questions, i just think switching to obd 1 is gonna make things alot easier!!
