I have the New T-6400 paired with ATV to ZWIFT. The KK control unit consistently will start buzzing really loudly and pretty much freezes up the resistance whenever I climb a 12% or greater incline. This first happened in the Tour of LDN Stage 2 about a mile or less from the end and then twice again today in Stage 4. In each instance, it’s nearly impossible to pedal (lowest gearing and the tire will slip and squeal) and I need to get off the bike and unplug the power to the trainer, plug it back in and reconnect, then I can continue the ride.
At one point in Stage 2, the resistance was way out of sorts before the 12% grade issue. I got a warning from ZWIFT that there was a problem with my equipment or missed my calling as a pro. LOL Certainly didn’t miss any callings!!
Anyone else have the same trainer and same issue? The trainer firmware version is 1.13 and I use the latest Android version of Kinetic Fit to calibrate. I use Wahoo speed and cadence sensors.
