You will still have the problem that Bafang's software can only 'approximate' the speed using nominal tire size. To get an accurate speed/distance one needs the actual circumference of the tire .... not the nominal tire size.

I’ll just be happy if it removes the speed limit!

I purchased the programming cable from Alibaba to remove the speed limit (20mph) on my CO-OP e1.1 (H500 drive system). Yes, it is that simple. The speed limit is now set to 37.5mph (60kph). Having said that, the battery on the e1.1 is only 36 volts so the max speed is about 25mph or so. Not sure if it's due to the current limit, back emf, or some combination of each.
