Hello everyone.
Im a 17 year old boy from sweden that is very interested in cars and everything surrounding it now i want to learn the basics of chiptuning me and my dad have worked on many different cars so the mechanical part am i pretty good at and now i want to extend my knowledge even more i just Googled Ecu chip tuning file forum and found this and thought it looked good so i registered an account.

So i have ordered an MPPS V21 to start off with right now i Drive a Saab 9-3 1.9tid 150HP with the EDC16 so what could i do with a MPPS V21 through the OBD port on one of these? And could i do a multimap on it?

(Sorry if i went off topic i just thought i might aswell squeeze it in there)
