There's a few of us thats had this problem. I had it with 1 car(04 WRX) that previously had a CobbAP , then unmarried, I had flashed it upwards of 20 times or so, then all of a sudden got that fault. I believe Ken(ride5000) ran into this issue also.
You must run a switched 12v(like a clock) to the jumper block. Normally you'll have to turn on the headlight or you'll get an overvoltage fault. There's a thread on
www.openecu.org about it.
