AFRs look a bit funky. Quite a large dicrepancy between the two banks.

Hard to tell what's going on with the Fisher-Price JB4 logging. No idea why they would scale the HPFP like that.

If you do another log start a bit lower down the rev range. From 3k onwards gives a better idea of what's going on.

Your hpfp seems pretty weak, even at upper rpm it's only at 1000 psi. Mine is over 2000psi on straight e85 and 21 psi.

Hpfp is fine, it's pretty much maxed out right now.

O ok thanks. I called bmw and they said it was replaced under recall in 08. Well as long as its holding up ok, im fine with it. Should it be maxed out though?
