You will find the full range of LT1 files here. Everything from completely stock LT1 files to files LT1_Edit guys have come up with themselves to LT1 files coming from PCMs done by professional tuners. The files here coming from PCMs by pro tuners are a very good starting point if you have similar mods to those listed. These professional tuner files were, in many cases, made for that specific car while on a dyno. It is not a good idea to just upload any of these files into your car and leave it at that. Rather, you should use these files as a good base starting point and tweak from there.

First you will find a listing of all the stock LT1 files I have. After the stock LT1 files, you'll find the files for modded LT1s. I'll place the new files at the end of each section so it will be easier for you to see the new files that I have added. I have provided all information that I have about the file. If I didn't provide tranny type, etc., then I don't know. Happy Editing!

Please note: The due to some changes in the server, files with a .LT1 extension can't be directly downloaded. I have added a .ZIP extension to the files. But, these ARE NOT zip files! I only added the extension to allow you to download them. After downloading the file simply remove the .ZIP extension and you'll have a good .LT1 file.

If you have an LT1 file you would like to contribute, PLEASE do so. Send it to me at...

bfranker@tampabay.rr.com

Remember to send a good description of what mods are done to the car!

Disclaimer!
Most of these files I have never even opened. I do not know how well they work or if they are even "safe" to use. View all files before uploading to make sure they at least look "reasonable" as they could cause damage to your vehichle if it is not the proper LT1 file. And of course, I am not responsible for anything that happens to your car while using these files as I only provide the web page for you to download them :-)

	1994 Z28 - A4 - 3.23 gears. Note: Not a virgin file. This file had an HPP+ uploaded to it then the PCM was returned to stock. I have heard that not EVERYTHING is changed back to stock as it is supposed to be. Hmm... So, can not be sure if this one is completely stock or not.

This program was designed for an overseas car and therefore does not allow car to go into closed loop.

Why, I don't know but do know that Modern Musclecar knows what they are doing! There may be something wrong with my car which is why it pinged badly.

	EXTREME WARNING: This file was created ONLY to pass emissions with a large cam'd car. Only use this file if you know EXACTLY what you are doing. Extreme damage could result if used improperly. Contact Chris Bennight for questions.
	The car is a 95 Z28 with an A4 auto tranny. It has BBK headers, off road y-pipe, Borla exhaust, free mods, Moroso cold air kit, SS hood, MSD 6AL w/blaster2 coil, and a NX 100 shot wet kit.
	It is a stock A4 file that has had the rear gears changed to 3.70 and has had * ALL the automatic trans functions disabled * It is not totally stock - since the gears have been changed already. This file was made for use with a retro automatic transmission like a TH350, TH400 or 700R4 that is NOT computer controlled, and that has a VSS and 40 tooth reluctor gear (like most GM automatics.) It was by no means intended to be used with a computer controlled automatic!! For additional info please contact Wayne Jeffcoat and he'll attempt to help ya out.
	Pro tune for mild ported heads, CC305 cam, long tubes, 3.73 gears, 11:1 compresion.
	This LT1 file is mine from my 94Z28 A4 blower car. It has very little changes as far as the engine tuning goes. The reason I am posting it here is because of the changes made to the tranny tables. My car has a 58mm throttle body with stock gears and a Vigilante 2800 stall. The stall has been modified so as to not slowly go into lock-up but rather go into lock-up such that it feels about like it is shifting into another gear. The tranny changes are such that when I take off from a dead stop and put it to 3000 rpm I can pretty much stay at 3000 rpm all the way until 60mph ;) I hated it when the car would shift into 2nd at like 5mph when I wasn't almost flooring it and that has now been fixed. Take a look and see what you think. The tables were changed by a buddy who really knows LT1 Edit AND works at a tranny shop... best of both worlds :)
