30ff code after fuel pump upgrade

rominun · 08-09-2017, 09:24 PM

Hello, I have a FBO 135i and I just add the fuel it inline stage 1 fuel pump. I had jb4 with bms backend flash. Went driving and everything went okay. Then I wanted to go and datalog with the mhd and the jb4 started to freak out by flashing the hazards and gauges. I flashed the stock map and turned the jb4 off and I'm getting a 30ff code. Not sure what's wrong. Turbos are brand new and I checked them just in case.

When I tried datalogging with mhd, it tweaked some stuff. The jb4 didn't like the mhd datalogging, so I turned off the backend flash and am running just the jb4
