1. Ramp test starts with 5 minutes of free ride and then 1 minute at 100W. Since i was not looking at wattages and only at RPM's in that first minute of 100W i was the entire time at approx 120W. Most likely it means that the freewheel is moving too fast, and the trainer can't hold keep low power. ...

Just performed JohandeWit workout in Zwift, and here are the results. The test was done with smoothing 2, and a 36x23 gear. Ignore the first seconds, it got stuck with the ERG bug, and had to put some watts to get it moving. Screen Shot 2020-11-24 at 6.45.35 PM.png Quite happy with the results to b...

@JohandeWit, Any chance can you export and share the workout and the sheet with the analysis, so we can try to repeat the same test across different devices? Pretty sure mine doesn't have the time to adapt issue, at least when going from a lower to an upper power, or at least I don't feel it, but ha...

Quick update and a wild theory. Today for the first time was able to get all the stars in a workout, which impressively was the ZA #7 - VO2 Development. Pretty impressed with the ERG mode performance today, honestly no complaints even about the multiple changes (Smooth set to 2). The only thing I di...

Enesto, looks like Johandewit is another engineer. Now, this could be fun. As for PID control, that would be interesting to see. I wonder if they have used digital filters. Time to dust off my understanding of Z transforms. ( That's about 30 years of dust mind!!!!) This thread is like an "Engi...

Hi, welcome to the club. Taking a look at the Marlin 5 , your bike has a 7 speed cassette, and a 7 speed rear derailleur. The chain which comes with the Directo XR is a 11-speed cassette, so clearly not compatible, and the skipping is more than expected. Your best chance is to either buy a 7 speed o...

Quick update. Just got update 73, and on a first quick test of 5 minutes, it looks definitely better, at least from the etraining app keeping the 2 as power smooth setting (6 introduces a huge delay in everything). Around 200W, most of the time, the fluctuations are between 190 and 210 or so. I Will...

One more possible clue, smartbiketrainers has HW Revision 003, as per screenshot of his upgrado app. Which HW revision you guys have? I have HW Revision 001 on my Direto XR bought 3 weeks ago.
