X5m missfiring

ACabrera · 09-21-2023, 02:51 PM

Hi guys!

I'm having kinda weird issue with my f85 x5m.

At wot if you let off the throttle and floor it again car starts to miss fire and have some fueling issues (bm3 stage 2 map).

Brand new low side fuel pump, brande new high pressure fuel pumps.
I could attach the bootmod3 logs. (make a overboost to 34 psi when you floor it again and then fuel system crash)

Has any of you guys have something similar?

Thanks in advance.

This is the E70 forum, not the F85 forum. Might want to try over there instead.
