Hi all, I have my GTR tuned with a Cobb (V3). In the past it was possible to switch the maps with the buttons on the steering wheel. Press cancel and the the boost gauge was showing the selected map. I have 4 maps. It was working I the past. Now I can still use the buttons on the steering wheel as before and the boost gauge shows the selected map. BUT the map does not change. The boost is always the same with 1,25bar. Even switching to OEM map shows this high boost. Fuel pressure is always stable at 80psi. Thus I believe the map is stuck at the mid boost version. Anyone with an idea on that?
I use to unplug the battery when the car is in the garage for several days or weeks. The mapping starts with the mid Boost version although the gauge states OEM map after plugging the battery.
I also reflashed the map from the cobb, but no change. Fuel is with 102 often and as the boost is always controlled to the 1,25bar I'm a bit frustrated.
