Hi, I had a problem with my wife's bike, getting the pas to work on the rhs sensor, but after some great advice, changed the display, access the c settings and changed c1, IT WORKED. THANK YOU.
However, the speed readout is now all over the place, dropping to 0 when I stop peddling. What do I need to change to sort this out? Many thanks

If your motor doesn't have a speed sensor, you need to get an external one. Either way, you set P2=1. Some motors have 6 magnets for the speed sensor which will make the speed display 6 times too high with P2=1. therefore you set it to 6.
