Mind showing a log that show constant 5bar to the HPFP?
mine is dropping to 3bar and 3.5bar at 7000rpm 4th pull tested using 305lph and 450lph respectively on OEM controller
running E10 fuel @28psi
logviewer below is with 450lph pump
Why is the pump duty cycle so high at that point on e10? If you're gonna run the pump that hard you'll need a torquebyte controller
