That's an interesting idea. The ECU was replaced along with most major sensors so it would make sense it's the harness but who knows. My concern is #1 tuning, I'd like to be able to mess around with it myself rather then having to worry about sending it out to someone or briging the car. #2 I hate dealing with electrical problems and would love a simple engine where if there's a problem it's ether spark or fuel.
