Default N63tu always kicking into map4. Help please - 05-30-2021, 02:08 PM

I have a 2014 550xi with the jb4 installed. The MAF's are unplugged and the BCM wires are plugged in. In map 1 the car feels fine. When I switch it to map 3 the car feels really weird and is very jerky and on WOT it'll kick you into map 4. Other maps do the same. There's good 93 in the tank. The car has ********* installed. In the log attached it kicked me into map 4 right before the 4 to 5 gear change. I noticed the boost is always over target and the throttle is always changing when the pedal is at 100%. Does anyone know what could be causing this and can help me out?
Thank you in advance

Try setting FF and FUA to 0 and lets see how that looks. Could be that you have the BCM wires reversed.
