Re: JRSC FPR setting? (Tiamat-blue)
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.

Sounds good, good luck with it.

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