Hi, New to the board.

I am interested in learning how to do my own tunes and mods for my vehicles. I have a Sprinter / Bosch ECU.

want to learn about tools (Kess V2 etc) and free software to edit files. I have general knowledge about editing hex files and programing controllers.

Also interested in learning about audi transmissions like the DQ250 and improving shift points on them.

Doing this as a hobby for my own vehicles.
