I'm not lookin' at the % readout, but actual voltage values. Even with the engine off, there is some voltage going through the meter and back to the ECU. I'm sayin' that the voltage should be different if the SAFC2 is dialed back.

Damn, my battery is totally dead, I was going to go mess with SAFC just to see if I could get some readings for you to try/eval. Sorry brah...

I don't see how ground can be a better ground than your pen15.

What about your injectors... Maybe stuck open or leaking....

The ignitor fixed it.

Injectors were replaced.

The ignitor sends the signal to the ECU from the CAS to inject, so I guess it makes sense. Doesn't explain the voltage though, does it?

It doesn't, but further testing does...

I checked both MAF voltages (before and after the SAFC2) while cranking and the differences were in agreement with the SAFC2 correction factor.

So, the SAFC2 receives my apologies for the names I called it.

Have you checked for any leaks at the intake manifold? Could be leaking air that was read by the MAF and throwing more fuel in to compensate but the air could be escaping from a leak. Just a suggestion...
