Im not very good with electric stuff, but I had a similar problem with my KA, where something shorted and my ECU was smoking. It ended up being a shorted out fuel injector, which fucked up my ECU and the whole car. So, take it to someone who can diagnose electric problems to be safe.

Maybe you should trace which pin it leads to and use the tech section to work out what the pin does, then maybe the more electricaly gifted people here would have an easier time helping you it figure out what went wrong.

That is so similar to what happened to one of my ecu's...
My case was a shorted MAF signal wire.
