MaxxECU Documentation

Added support for the Rover K-Series VVC (18K4K) CAM.

Added new reactivation delay deactivation options to either keep or disable lambda correction during throttle changes and/or fuel/ignition cuts, and fixed an issue introduced in MTune .161 where lambda correction was incorrectly held during throttle changes instead of being disabled.

Fixed an issue with the oil pressure cut where negative oil pressure values could be interpreted as a large positive value, preventing the protection from activating correctly.

Fixed the background light for 8HP BMW M5 F90 shifter and N to D while in motion is now allowed for the F90 shifter.

Fixed a silent MTune crash on Windows 7 caused by a missing DPI awareness DLL introduced in MTune 1.161.
