Ok so there is nothing wrong with my Power FC. I found a list of the pins on the ecu connector and found that there are 3 ECCS wires. One for ground, one for back up power and one for power. I found only the backup wire had constant 12v. The other power wire had nothing. So I jumped this pin and voila, Power FC and Commader came to life. car started up and everything.

I still have a problem. My Power FC wont save any changes. The only changes it saved were changes to the injector values. This is when I had constant power to both ECCS wires. I ran switched 12v to the eccs power wire since the Commander wouldnt turn off when I had constant 12v running to both wires. Now it wont save any changes to the maps, rev idle, nothing.

Is anyone familiar with these ECCS wires? What is ECCS?
