I Want To Tune C4's--Whats Needed?

Minus the dyno, and a lap-top...I want to know what programs are available to tune LT1's, 4's, and 5's.

Two dyno's in town here, one does NOT tune...just does runs...the other only does LSx cars.

I have to drive to Baton Rouge for my 96 LT1 (a little over 70 miles).

Since Impala's, Camaro's, Firebirds, Vette's, ect... use the LTx motors, I am wondering what programs are available.

I have a lap-top to dedicate and my buddy has a new dyno, and the probe/unit for checking air fuel ratio's at the exhaust.

I want to be the guy that adjusts like PCM for less, only doing it on a dyno using real-time/live performance numbers while under a load.
I do understand ther will be different cables for different models, makes, and years.

I just dont want to get a program that is just limited to wheel size, speed-0 limits, rev limits, tranny shifts, ect... like a hand-held tuner.
I want to adjust air/fuel, knock sensor, Idle. timing, ect...

I need facts.




Thanks,
Jim
