Bugs
AI Multiplexer CH A1: calibration mode: curve --> no function
demuxed_chA1_cal-mat
I think it needs to be mat-demuxed_chA1_cal
Firmware wishlist
- multiple custom sensor curves possible
- possibility to rename AI channels
- create virtual channels from several channels with basic mathematic operators (not only display them by custom expression)
- delta to lambda target instead of fixed lean threshold for warning light? 2D map: difference vs rpm or 3D map: Lambda warning threshold vs MAP(or TPS for AlphaN) vs RPM
