I bought an Elite Qubo Digital Interactive or Elite Digital Smart B+ (not sure the difference), I have downloaded the Windows App and I have paired with Ant+ to the trainer. When I go into settings it has the roller size as 47mm, but the trainer has 30mm roller and it will not allow me to change the size in the software. This has to be messing up the numbers that are being output for speed, watts, cadence, etc... Maybe this is why in Zwift it does not seem to reflect my speed and power very quickly when I increase effort, like in a sprint. Is there a way to change the Map file so that the correct roller size is used? Stickers on trainer S/N:27045 Firmware 141

Hi

If your trainer has a 30mm diameter, it meanst that its circumference is 94mm. As your Qubo Digital Smart B+ has 2 magnets inside, the app also take this value and divide it by 2, so... here you have the 47mm

With my e-training Desktop software do you have wrong speed or power? Or only with Zwift?
Are you using Zwift in simulation mode? Do you connect using bluetooth or ant+?
