That is cray-cray. Funny, my C622 puked its guts out, as well. If we had the schematics, troubleshooting broken tracers and pads would be a breeze. I don't see too many OEM ECUs on the market, so keeping mine was important to me for the auto transmission. If not, I was going to bite the bullet and switch to a ProEFI and not look back. I still may switch soon... who knows. I change my mind daily. I've been BPU since 2001, so maybe it's time to unleash the beast.
