I recently bought a Megasquirt unit off of a member, that bought if off if another member, and was supposedly a good working unit that was pulled out of a running car.
I went to plug the ecu in, and as soon as I turned the key to load the base map, the 02 sensor wiring became very hot and started smoking.
No connection with the ecu through the laptop. Board does not have an LED light.
Taking the board apart, I can see jumper wires ran to different points and there were a few screws that were loose and rattling around. The board says V1.5B and the adapter is B55 DIYPNP V1.2.
I checked the power at the harness and it seems to be supplying power to pin 18, but on this board pin 18 isn't even soldered to anything. Pin 37 goes to 12v, then from 12v to main relay out, then main relay in to pin 27.
I am so lost. I don't know what I need to do or where to go from here.
Was I sold a bad unit? Should I just request a refund? Because this is not how it was described to me and now I'm stuck with a bunch of parts I may not be able to use.
Help a guy out?
