K dumb question but how do I adjust the fuel pressure on my jrsc? I assume "tighten" the allen screw on the top of the FPR?

 

You can adjust Static FP by loosening the nut and turning the allen screw ccw/cw.

 

Ok that's what I thought, but which way? Cw to raise/ccw to lower I assume?

 

I have a friend with a JRSC Prelude SH. Off the shelf JR kit using the included FPR. Trying to tune the system and driveability just really really sucks. It was super rich and Ive learned it out a tune by adjusting the FPR and it doesnt smell rich anymore at idle and it idles better however it bogs and bucks like crazy under 3k rpm. Above 3k rpm it drives ok, but its slow, stock was faster without the supercharger.

But you still haven't rectified your MAP sensor issue that is causing your MAP CEL, which per our discussion is most likely a wiring issue at the JR "ems". You really shouldn't be messing with the static fuel pressure without a fuel pressure gauge, a dyno, and a wideband, and you shouldn't be boosting on it until you get fix all the installation bugs that you have. Be careful or you are going to blow your friend's H22 very, very quickly.

 

Thanks, I posted this question before we talked via PM. Fuel guage has been ordered and I am bringing in a friend who is very good at wiring and si going to go through and solder all the connections.

Sounds good, good luck with it.

 

I just want to find ONE JRSC user who has their car running GOOD with the JR FPR! Prove to me it can be done. I dont think it can.

 

It is possible... I'm doing it. I run a stock JR FMU, drilled regulator, and VAFC.

Hey just noticed that you are in Western MA? PM me and maybe I can help you figure it out - and no, I'm not going to steal your car

 

Thanks but Im in NY. The original, the bigger Rochester!

 

i am getting ready to put one on my GS-R Sat. I will let you know then
