The terminals are clean and everything seems to be plugged in tight. The headlights light come on and the engine turns. When it turns, it dims the lights.
It's too dark and rainy to do more tonight, but tomorrow I will take out the ECU and the TCU. I need to check that the stage 1 chip is in the ECU tight.
I have spares of both of those computers so I guess I can try replacing those. Sure hope I didn't break something.
