q-rover Posted August 16, 2009 Share Posted August 16, 2009 How does it work? Is it similar to the P38 in that it receives a signal from the ABS etc, via the BECM? Or is it simpler. Wondering on how to recallibrate it if fitting larger tyres. Quote Link to comment Share on other sites More sharing options...
BogMonster Posted August 16, 2009 Share Posted August 16, 2009 IIRC it takes the average speed from the four wheel speed sensors - presumably this then goes from the SLABS ECU (as that reads the input from the sensors) via CANbus to the instrument pack, though that is just from memory and I haven't double checked it by looking in the book. No idea how you would go about recalibrating that though Quote Link to comment Share on other sites More sharing options...
q-rover Posted August 17, 2009 Author Share Posted August 17, 2009 Probably the same way I did it on my P38. With a clever box of magic, that has some wires coming out of it. Quote Link to comment Share on other sites More sharing options...
