Flashed JB4 Backend => Now runs at 10psi of boost?
On my journey of discovery for my third owner 2008 135i, I found a JB4. Thinking it would be a good idea to update the firmware and add a backend flash, I followed the instructions on the n54tech forum, and did just that without issue. I flashed the JB4 BEF "JB4_IJE0S_PUMP". The car previously had MHD stage 0.
Running on map 2 (unchanged from before the BEF), the boost now peaks at ~15psi then gets pulled back to 10 psi - see the attached log screenshot. This happenned consistently. Does anybody know what might be causing this? Have I stuffed up a setting? |
