I have a .lt1 file emailed to me from pcmforless for a supercharged 97 WS6 and i am using tunercat to program the pcm. I tried using Musser's convert program but i am either doing it wrong, or its not working on my laptop for some reason. If i emailed the file to someone in .lt1 format, can someone convert it to a .cal format and email it back to me? I would GREATLY appreciate it. thanks

What program do you use to take the tune from pcmforless from your laptop to your car?

 

Why do you need to convert it. Tunercat will open a .lt1 file.

 

I am using tunercat program for the 96/97 lt1's. I didnt know that tunercat would use a .lt1 file. All the files i have on the laptop are .bin for 94/95 and .cal for the obd2. I thought the .lt1 files were for people using lt1 edit. I'll go try it again and see what happens.

Tired to open the file in tunercat tuner and it said it wsa corrupt or incompatible format and wouldnt let me open it. Tried to program it in winflash and it said unable to prgram, incompatible format. I think it needs to be converted from the .lt1 to .cal. can anyone help me out?

Tell Bryan what your doing. He can convert it for you but it takes 3x as long.

 

I emailed him about 1 am this morning about it. i figured he could convert it somehow, just waiting for a reply back. thanks

Sorry, I assumed that it was OBD-I, since your sig is for a 1994 and there was no mention of a conversion or if you were dealing with some other car.

The Tunercat I have for OBD-I opens .lt1 files with no problem. You just have to change the default file type when you go to the files_open window. I don't know if the OBD-II version has the same thing.

 

It doesn't. OBD2 will only open .cal or .bin files
