I have a bmw 335i e90 st_pi_e85 bef. it breaks up around 5000rpm I have a map 5 log I’ll include below. But from what I see the ecu psi is at 17psi while the actual boost is at way over that.

any help would be greatly appreciated.

Are you getting thrown out of map 5 into safety map 1? If so check last safety map in the jb4 user adjustment tab, also what do mean by breakup?

I can’t seem to see your hpfp and lpfp readings but what I see is you WOT then the car just basically stops revving which sounds fuel related to me . What’s your fuel set up?

It doesn’t kick me out of map 5 I think it happens so quick it’s not detected but fuel setup is stage 3 precision racewerks lpfp with recently replaced regulator index 12 injectors and 900cc on the pi
