I am a car mechanic (learnt that a few years ago) and I study electronics engineering in Germany. I have a Seat leon 1.9 TDI and want to get inside modifying ECUs to increase power. I have done that to a few cars before - that was easy as they did not have ECUs for injection Pump and Turbo. Now I want to learn how to do it with that "modern" cars ;-).

Welcome.
