Hi guys. My name is Chris. I've worked with Daz before on setting up the ECU in my C5 4.2, and as of recently I've grown an interest in how these ECU's work. I've done the basic reading/writing of files, but now I'm trying to get my feet wet with WinOLS. I got a ways to go; I can load a .bin file but I have no idea how to load a definition file for the bin I opened yet. I've seen a wealth of information on this site, and I just want to try to learn as much as I can with VW/Audi ECU's.
