Dear all
I need you to help me to learn about ECU technology
my aim is to understand how to diagnose, find problems, update software and deal with other issues (immo off )
kindly guide me for these
Thanx

Same here.

I am starting with a Bosch EDC15C2. I think you need to focus on one thing at a time. Research that as much as you can and regurgitate what you know.

Hopefully there is good support for newbies on this forum. There's lots of great posts. Sifting through them is another matter which is why I am focusing on one ECU for now. Though I am not sure I've picked the easiest project to start with.

It takes many years to become an expert in something like this and a daily advancement towards your goal must always be strived for.
