BMW X1 35i Stage 2 Plus Logs
5th Gear log used the standard throttle mapping while the 3rd Gear logs were switched to the linear mapping. The 5th gear log was taken to try and troubleshoot some car shudder during half throttle input. At full throttle the shudder disappears. Pulled fuse number 40 to disable the transfer case and the shudder was still present though slightly reduced. It would appear that high boost at a lower RPM (2,500 - 3,000), particularly 5th gear, causes the car to shudder. It feels like the power momentarily cuts, comes back strong, cuts again, and so on. Both 3rd gear runs felt clean with no shudder.
