What's the URL for that program you can download so you can scan your car by your laptop?

Also where do you get LT1 Edit from?

 

Just type in Andy Whittacker and Freescan in your search box. Datamaster also gives you 20 free scans with there software.
Tunercat's cheaper at $19 for definition file and $69.95 for the program. I just downloaded there free 30 day trial and bought the definition file for $19. I'm going to purchase it though. Once you start programming, it get's addictive.

 

Freescan is just diagnostic then and Tunercat is like LT1 edit?

 

Correct. Datamaster is nicer with graphing capabilities, but Freescan gives you everything you need in spreadsheet form. Now you just need to start studying. I've spent over 30 hours looking at stuff on the internest, camaroz28, and other sites, just to get the basic's down to where I know what most of the tables do in Tunercat and where to change things. If you have a M6 there's a little less to figure out.
