Ohh I`m getting tired of people that must tell others that : you cant fix it/ you cant make it. I wonder where the world would be if people just sat there and say : somebody else has to do this. Stoneage?
I had a problem with a car amplifier some years ago, I have to say that I`m a nobrainer regards elektronics but I call a frend that told me where to Ohm and I find a transistor that had failed, replaced it and the amplifier work`d! and it still does!
So I also think this ECU is a easy fix
