Mike - what is your sensor for your e-Jones? I can't see the photos now, but I don't recall seeing the sensor shown.
I re-programmed by electronic VR counter last night, and it tracks the Jones clicks every 23 2/3 clicks. I have a magnetic sensor, so it registers every wheel revolution. This will allow me to get close to the spot, but I will still have to look at the Jones for a reading between full revolutions.
Just wondered how you are handling the sensor, so that you increment on your digital counter for every Jones count.
