Yeah, 2240 is the Flow Smart and will do the auto resistance thing in Zwift…
I’ve just got one and have quite a bit of problems so far, although potentially sorted out now (will find out this evening).
First thing to do if you do get one is check that the bag of qr skewer, bolts and Allen key are in there. First two I had didn’t. In the end they took the bag from another one model of trainer….
I think to get it to work with Zwift you need to update the firmware. This is where I have been having issues. Doing a firmware update to the letter managed to kill 2 brake units stone dead.
Tacx have sent me a new brake unit updated from the factory, which I calibrated last night and I’ll be trying to pair it and have a session with it tonight.
Tacx reckon I was ‘unlucky’ with my firmware update. I have my suspicions that it’s due to my old phone and version of Android but that’s just a guess.
