Ecu problems ?

[jinesz32]

I'm having issues with my car.

I was driving it today and All of a sudden the gas doesn't work and my rpm starts jumping like crazy and the car just turns off. I pulled the trim off where the ecu is and I see smoke coming out very very little. I'm guessing the ecu is fried.

I got another ecu but I don't know how to set the little knob behind the ecu . I plugged the old ecu in and the light is red. I don't know what any of this means . If anyone could explain to me how to set the knob clockwise / counter clockwise etc and why the light is red on my old ecu I'd appreciate it.

Thank you .
