Tacx Flow Calibration - always too loose

Don't give it too much importance. The coefficient for power is still determined and memorized by the trainer. It is important that you do not have tire slippage on virtual tracks.

Thanks for the explanation, Alex, really nice to know.

Rafael, Alex, I have the same issue, I get "Calibration Successful" if I calibrate on the Garmin (530) but have never had a successful calibration with the Tacx App (iphone),

Alex, the only options with the calibration screen is a sucessful calibration or "skip", are you saying that if you "skip" it still updates a coefficient as this is not my experience?

ALWAYS says its "too loose" after the 30 kph test and the marker stays at the left corner

Rafael, do you mean "right corner?

Hi there.

Yeah, right corner, actually Tacx Training and Tacx Utility have different sides to show "too loose", since I tried on both I cant really remember wich one is the "right" or "left" side hehe, but its exactly like in the picture, stays in the corner where says "too loose" no matter what and on both apps.

My explanation for this is this: the developers indicated in the application the wrong limits for the calibration coefficient for this model of the trainer. The coefficient itself is determined, remembered by the trainer, but on the red-green scale it is displayed as out of range.

I have the same problem.

I tryed with 2.1.2 versione of Tacx Utility but no lucky.

How can I solve the "too loose" problem?

Thanks

I would like to be able to offer you a sure fire solution but my Tacx Flow(s) always had calibration problems too. My first only calibrated with the roller pressing so hard against the tyre that is was almost impossible to pedal and eventually, (10 months), the blue lever broke due to the excessive pressure. Garmin replaced the resistance unit (thank you) but I was never able to calibrate the 2nd unit, always "too loose". I tightened the wheel as much as possible without the barrel nut coming off the bolt but it never calibrated. Garmin were going to replace the whole unit again as the "experts" at the Tacx factory agreed there was some problem possibly with the frame but months went by and Garmin could not get stock in my region so they eventually refunded my money and I (still with faith in Tacx) purchased a discounted Flux S (still going strong).

There are numerous flow "calibration problem" postings here and some never seem to resolve. Some possible solutions include using variations of the mounting holes, ensuring the unit is warmed up before attempting calibration.

I found (oddly) that while the Flow would not calibrate with the Tacx Training App it would calibrate if using the "Calibrate Indoor Trainer" option on my Garmin 530, in fact it always just calibrated without any adjustment to the roller pressure. Garmin says you can calibrate with the Tacx App OR the Garmin, https://support.garmin.com/en-AU/?faq=sdgdMoFqDn06eLSYFrnrg5 ,don't know if other cycle computers have a calibration option.

GPLAMA says in his Flow "unboxing" video that you should tighten the adjustment only as much as needed to ensure there is no slippage against the tyre, maybe give that a go and then just use it ignoring the Tacx App calibration required prompts.

My Flow was my first "smart" trainer and apart from the calibration issues I liked it, used it for a few thousand kms but the direct drive trainer (the Flux) is much better, more realistic and a much better workout.

Good Luck
