My Aveo ECU hacking journey has begun

[06T200]

A peek inside of an MT34 ECU for amusement..

It's a Hitachi board with some high end chips, notice the Hitachi logo in the lower right corner.


This particular unit was given to me as a 'broken' unit, it has nothing on the serial port, but I do see reference voltage on the reference pins, but no data on C31. With any luck I can reflash it to use it again.

Very nice quality work!
