Thread: RRFPR problem
06-28-2012, 10:29 PM #1
I have the aeromotive 13109, and I am currently using the reference line to have the 1:1 ratio with boost. However, when I use the reference line, at WOT my afr just drops to 10.2 causing me to be pig rich. I started the base pressure with key in and engine off at 60 psi, and saw a 1:1 with my fuel pressure gauge and my boost pressure gauge. I went down to 55 psi, and still no change. The afr was still 10.2.
I then took off the reference line, and dropped the pressure down to 52 psi. At WOT, my afr was around 11.2. I then called it quits since it was getting dark. What can be the problem with my regulator? Can the diaphragm be bad where I will need to rebuild it?
My setup consists of
Bosch 48lb injectors
Fizzle XS IC
4" Front air intake

Has it been in the boat working properly. Is this a new addition? Seems like even if you had no RRFPR you wouldn't need it! Your rich enough at WOT.

what are your afrs at idle and 6000rpm?

Afr at idle is around 11, and at 6000 rpm i THINK it was around 11-11.3. Kinda forgot now. lol

How do you have it routed? It sounds like you have the lines mixed up.
