Our cars (e82 n55) do not have LPFP sensor so the numbers you see in the log for that field are irrelevant. Now that you have the FF wires you need to look at HPFP and trims values. If they are good then your LPFP is good.

Misfire codes. Let's see a JB4 log at lower boost levels like map0 or map1.

First of all, get a log as per Terry.

HPFP value will vary depending on map/fuel demands. Iím seeing 15 and 16 on map 6 with a 16psi target (I canít go higher due to snow tires on the car). Iím also getting some trims up to 32 momentarily then back down to 25.
