Electrical ecu

New ECU's or used ones are extremely difficult to find.

Dan02gt is correct. Before you go and buy a new one, open your ECU and check for the burned trace. If it is burned, you'll have to figure out why it burned open before you install a new ECU or it will just fry the new one too. It could also be one of the three electrolytic capacitors on the other side of the board have gone bad. It's not a hard fix if you're handy with a soldering iron. The caps are cheap and you just have to run a small jumper around the burned trace. I've attached pictures of mine and circled the area that burns and where to solder in the jumper. The other picture shows the three capacitors that should be replaced.
