Hello ! first of all a very big THANKS for all the tips on this issue.
Applying all what you said get the R1 better there is no doubt. I ve done this if it could help…

I am happy we are getting somewhere with trainer that was almost useless. Anyways, power numbers from the trainer are completely off and use of external power meter is strongly recommended. I think Kinetic did not use thermometer inside of the trainer to compensate for the power variance. I had readings off by well over 200W. As for the fan solution above, I would suggest another cooling solution for the stepper motor which is the main culprit drugging down this trainer. For the permanent solution so I can close the cover I think this cooling heatsink will work:
Or something similar. When I have more time I will look into this further.
@Pawel_Kielce @Serge_Rossi Pawel, before I did your fix the only way I was able to get the power readings close was to drag my foot along the drive wheel during calibration, I did this several times settling on 1.24 in the kinetic app which measured against the stages power meter was pretty close. Once I did your fix and started cooling directly, that threw the calibration off again. Currently I am running a stock calibration that came in at 4.9 in the kinetic app. But that too is still way off. It simply does not read correctly in the hills. Always low. And from the one graphic of my sons ride I posted you can see a 300 watt difference in the peak power of his sprint. Question for you, where did you get that little heat sink you put on the chip. Do you think something like that would be beneficial if they were place something like that on the stepper motor?
Sounds like all those trainers are acting in a different way. Mine was closest to Stages with calibration around 5. I could only get 5 with dragging my foot against the belt wheel. Normally it calibrates in the neighbourhood of 6.3. I read some forums with statements about best consistency to be around 3.5.
Personally I don’t think this fix is affecting anything but I could be wrong? Currently I’m trying to only cool off the stepper alone so perhaps blowing cool air on other parts of the trainer affects power output. But with use of external power meter I don’t care about it anymore. I got the heatsink from my Raspberry PI kit, there was one extra sent out. You can buy them from Amazon. if you search for Raspberry pi heat sinks it will come up. As for applying hit sink to the stepper, I’m just thinking about cleanest solution so I can close the cover and forget about it:)
