Injector psi and hpfp psi at idle?

cstmx_ryder · 09-26-2014, 04:22 PM

Guys,

What's the injector and hpfp psi at idle? Or voltage?

Just trying to diagnose the rough cold-start and idling issues.

TIA

LPFP around 72psi, my HPFP starts off around 2200psi and tapers to 700-800psi

At idle is between 650-750psi with 700 being ideal

700 on the nose more or less.

How do you check the injectors using cobb ?

You can't. Nor with a BT cable (ask me how I know).

Need INPA

Ok thanks

cstmx_ryder · 10-10-2014, 01:57 PM

So INPA can log hpfp and injector pressure?

So all the above is the HPFP psi, right? With the exception of 72 psi.....

How about injector at idle?
