Long story short, SMEC would cut out at a spot of freeway by downtown L A Ca. Key off then on it continued to work. Replaced 3 compacitors and worked perfect for 100 miles before problem came back. I plan on rebuilding the power and ground sides of the board. It's seem that pin 12 (J2) curcuit may be the problem. Has anyone traced this curcuit or repaired this before ? I'd loved to get a diagram of the board but never could find one. I converted back to stock 2 bar SMEC in the mean time which is no fun at all since the the car doesn't pull very hard at all.
