Re: Need Help with ECU Ground(s)

I do have a build thread on SVTP, but it hasn't been updated for about 8 months. That's how long I've been trying to solve this WOT problem.

I'm 99.9% sure I finally found the issue: my damned CCRM is plugged in backwards, for sure. So when I go WOT, instead of my A/C clutch power being shut off, the PCM power is. This also explains why my fuel pumps don't timeout under accessory power. I verified all of this by looking at a CCRM wiring diagram, considering it with a backwards connection (i.e. the PCM power relay and A/C clutch power relay are at the far opposite ends, as far as pin connections go).

Once I make more than 20rwhp, which should be very soon, I'll definitely create a thread here to share the build. To understate the matter, it's been quite the journey.
