i've got a '94 LT1 out of a 9C1 Caprice, and i'd like to swap it into my '92 C1500. i'm going to work on integrating the LT1 harness with the existing engine harness. i'd like to upgrade from the stock ECM setup, to something that can be tuned with a laptop, to avoid chip burning and such. what are my options here?

tunercats would be a good program to use, or lt1 edit. u will need a cable to go form the laptop to the PCM, and as usual i cant find the link for the cables lol
Program: Most of us use Tunercat. Go to TunerCat. You'll have to buy the def file for $20. If you buy the program you get free updates.
Cable: I bought the kit from aldlcables and built it myself for $45 but i have heard there are cheaper ways. May also need a usb-to-serial converter, the one made by Belkin is recommended.
Scanning programs(not needed for programming just scanning like for codes, etc.): Freescan(Free), Datamaster(Free trial), Scanmaster(not free). I like datamaster.
Still learning also but if you have odb1, maybe odbii but not sure, then use tunercat. Most say lt1 edit is not worth the price and at the much higher cost you can only do one PCM unless you serve large for each PCM you want to tune. The guys at camaroz28.com seem to think tunercat is the best choice. I am sending mine off for the first tune. Also just read that pcmforless locks the PCM so you can not store the files and if tweaking does not produce a desirable result you have nothing to restore. Listen to others first though as I am not even close to novice......yet. I do lots of reading before I dive into dark waters.
