Car hitting 17-18 PSI on MAP 2?

MrBimmerM235i · 07-17-2016, 10:47 PM

According to the JB4 Bluetooth App my car is hitting 17-18 PSI... Someone here with the same issue or the PSI Gauge in the app is not accurate?

without a log we wont know exactly
but yes it could peak into 17-18, is your boost safety on 18 or 20 ?
did you post it on n54tech.com ?

Post a log. I have a feeling it's a boost spike when you shift.

Mine was hitting 17-18psi also. What fuel are you running and are you FBO..? I was told all is well and normal on Map2... Do you have EWG wires tied in ..? If so try running map5, see where JB4 dials in and post a few data logs on N54tech. Those guys will give you good advice...

Probably a boost spike at shift and or with throttle closure.

Not impossible, but you'll only see that sort of boost in higher gears (probably 5 and up) due to the load targeting.
