Need a stock tune for a 99Z28 (LS1Edit) Any chance I can get a pcm file for a stock (or nearly stock)F-body?
I last tuned my car over 4 years ago, and it had a cam, converter, etc.
I need to realign fuel, ignition, trans tables, idle, etc with something more along my current setup.
Right now it's a stock 98 vette motor with longtubes, no cats (ORY), FTRA, and it has a stock converter.
Not looking for a custom tune, I just want to get this thing tamed a bit. I got the idle back where it needs to be, and the shift points closer, but the throttle cracker seems to be giving it a cruise control effect, and I don't remember stock values in those tables either.

I have almost all the F-Body + Y-Body programs from 1997 - 2002 for LS1Edit 
Which one do you want?
You have a 98 vette engine and what PCM?
Mechanically the vette engine is about the same as the F-bodies, but the fuel system was different: they had a pressure regulator in the fuel rails and a return line.
At that time the F-bodies already had a semi-return system with the regulator in the tank.
Depending on the PCM and on the fuel system you'll have to take a different program.
Is it an A4 or a M6? The programs are different too.

), has the F-body PCM and fuel rail (but vette injectors). If you have something that'd work, I'd really appreciate it. It's not bad now, but I can tell the throttle cracker table is probably off, and the shift points, while I have fixed them somewhat, still aren't perfect. I have no clue what changes we made to the fuel and ignition, that was so long ago.
