BEGi fpr question
 

Just finished my bandaid system. Instruction from BEGi says that pressure gauge should show you 28-30psi at idle but mine showing 40psi, whn Im pulling signal line it shows 47-49psi, so what is a problem? and wideband all time showing different numbers sometimes it 12 sometimes 15.5?????

Wow.

AFRs, through my very unprofessional experience should be ~15:1 at cruise, maybe a little less, ~13.0-12.5:1 at tip in and 12:1 in boost, less depending on how much boost.

Pics of how the FPR is routed.

I followed begi instruction

You can adjust it by backing off the nut and threaded portion on top of the
Begi unit. Loose = less pressure if I remember correctly.

Yes you can ajust it with nut, but it won't go lower than 40psi with signal line in

I mean with signal line off gauge read 47-49psi, so thats numbers good follow begi instruction. But when you put signal line back on fpr it reads 40psi but begi manual says that it should be 28-30psi. And a wideband goes so crazy. I started car today and at idle number was 12.5, yesturday night time was 15.5 and early same day was around 12
