yeah yeah.

And, by "caused by bad wiring", I mean that the ECU damage is caused by bad wiring. I've seen so many burned up ECUs from wiring MAF sensors wrong, "upgrading" the fuel pump wiring/relay incorrectly, poor ground connections when reinstalling harnesses, etc. Sometimes this can be repaired in the ECU, but a lot of times there is damage that cannot be seen. Moving ROM boards to a different ECU is not hard if you're handy.
