Got a diesel x5 with the m57 diesel engine.
Run/stall quickly.

On ista, i am showing about 100 bar low on actual rail pressure vs specified.

Likewise, when running the low pressure fuel pump, the desired RPS is 4000 something and I only show around 2700.

Wondering if the fuel pump speed specified is real or not. I don't have a 3 phase pump. just pulse width modulated control.

Can anyone test this on a running 35d? I am trying to determine if I need a low pressure pump or a High pressure fuel pump.

original issue was stall at high speed. eventually got it running, but can't get any extended run time anymore.
Thanks!
