fuel pressure with the r2 reprogramming?
what fuel pressure should your fpr be set at with the r2 reprogramming?
the instructions for the reprogramming only reccomend 91 to 93 octane.
i have not read anything about fuel pressure setting.
maybe most people do not use a fpr with this setup!

I have my RRFPR set at 55 PSI with 550cc injectors!.

going to re-check the AFR this weekend. i had the rising rate connected before. but, i am thinking it was to much fuel pressure with the oem injectors.
so i was thinking 48 to 52 lbs on the fuel pressure gauge.
maybe a better question is " what is the fuel pressure of the oem fuel pump? "

My AFR's were 12.6-12.7 at idle with my Riva FPR UNTOUCHED from Riva.
I've been told to start at 52 PSI and go from there.
My thinking is to set it off the AFR's... Does this sound right?

Will the pressure at the FPR be the same as the pressure at the "rail" (I think that's what its called)?
I have the R&D inline pressure gauge and it reads 54..... ???
And it sounds quite rich at idle.
.....AFR gauge set up to go in this week, finally!

AFR or lambda is going to vary from ski to ski as the fuel pressure will as well.
Best thing to do it log the AFR or lambda through the entire rpm range and adjust the fuel pressure as required.
