JB4 Error codes and boost issue
I've got a 2012 135i w/N55 engine.
Running Injen cold air intake, VRSF Downpipe and JB4 I did a recent datalog pulling from about 2100 RPM to 6300RPM and my boost is showing at a max of 12.7 at 5200 RPM with a target boost at 13.9 The car honestly feels relatively the same in Map 4 and Map 1, 2 and 5. The only error code I get from the JB4 is 3427 or 3429 and I don't know if there's correlation between the BMW code P3427/9 Any ideas as to what is going on? |
