drc38 1 Report post Posted December 14, 2015 I needed to change the battery on my E87, given I needed to register the battery via coding I also implemented a few other coding changes including: adding instantaneous digital speed read out v = xx km/h adding comfort close of windows, mirrors and sunroof by pressing keyfob lock adding auto key eject when turning off engine with stop button changing wipers to complete full cycle after power off I also picked up on a thread that suggests on a manual transmission the efficient dynamics shift selection can be added, coding as per the instructions gives me the up down arrows but no shift suggestion as per some others comments. Has anyone else tried this, got it working? Or have it already on their E8x or E9x? Can anyone recommend other useful coding changes to implement?
