Stock LT4 (1996) Tune Requested
If anyone has and could forward a stock LT4 ECM tune for Jet software it would be much appreciated. (Tuner requested so he has a baseline tune criteria to remove). Thx! a

I think this is what you're looking for. It comes from here: http://www.gearhead-efi.com/Fuel-Inj...ll=1#post68558
The problem is that most stock tunes from the LT4 are from a very long time ago, when people were still using old software that encrypted the output so that you couldn't mess with it unless you paid the company money to be a tuner.
Perhaps soon we will have a free, open-source method of reading and writing to these OBDII PCMs, at which point I imagine it wouldn't be hard to convince a '96 owner to pass along a stock tune.
Best of luck!

Here you go from my stock LT4 GS. I had to .zip it because the forum wouldn't upload the .jcl file for some reason.

Thank you!
Not sure that I sent out a thank you for the replies to my request for the factory LT4 tune. But much appreciated and they did assist the Tuner to establish a starting point. Thanks to all for your help.
