Hello everybody!, I work as mechanics teacher in Mallorca, Spain, and I found your forum because I blocked a bosch ecu just playing with it.
My work mate needs the car to work properly for her classes.... and I will have to learn a lot from you if I don't want to have problems!!....or just order a substitute from the junkyard.
I use Megasquirt and arduino to multiple purposes on my classes but it's important to play and know how to work with commercial ecu's.
I have electronic skills because I'm electronic engineer with experience on micro-controllers. And it's frustrating the little official information that there's available from cars systems compared to other systems!!
So, Thanks for sharing with me your knowledge.
