    I put the Cylinder Gain back to Disable, and fuel pressure is commanding and following as it should.
    thanks for the update, glad we could help Good to know the Cyl Trim still isn't working though.

    Awesome thread, unfortunately I'm a slow learner lol

    My IDC has risen since E85 so I added the DSx Aux pump. But I still see my Fuel Pressure start around 70psi and drops to below 58 or so while doing a log. About this same time is when Lambda goes up to 81-82ish. I still haven't downloaded the FPCM from HP but for starters does this look correct for the ecu settings?
