In the past I found some remarkable resources on just about any topic here so I'll shoot my shot.
Does any of you wizards have pdf books or any other treasure box of knowledge regarding ECU mapping and Chiptuning or whatever you want to call it? I'm already an electronics technician and have some knowledge on automotive electronics but want to get into this field in particular. Can't seem to find any course material online tho.
Big thanks for the help, and have a nice day!
