Jared, just got your PM. I don't have tuning software for your car.

The SE/SLE fuel pump is NOT the same pump the SSEi gets. That could very well be your problem. I assume you're running the L67 FPR?

Beats me. I would imaginge it'* outside the range of human hearing. Anybody want to hook one up to an O-scope and see what it'* listening to?

Looking at the specs, the signal to the ECM is an AC wave, 2.5v, and the amplitude sets off.
