 @hgavert It is in the watch. if you enter your max HR, it asks you if you want to adjust your zones automatically. 
 I don’t know what model Suunto has based it’s zones on, but you can always adjust your zones manually if you like.

 @surfboomerang said in S9 Baro titanium not measuring VO2Max or fitness levels with 2.10.18 - is this a known problem?: Thanks, that was interesting read! I will try that test maybe next summer if my foot allows me to run. However, I went back to the watch and toggled the max HR and finally when I found the clear or default settings, then it changed the zones to something more reasonable. Still based on the max HR of course. 
- 
 @hgavert Your zones are clearly off. Zone 5 is for interval efforts, most cannot maintain HR in zone 5 for very long. For an setting based on effort, Zone 1 you should be able to converse easily, and talk as long as you want. Zone 2 you will need to breathe more and that will interrupt conversation some. Zone 3 a sentence, Zone 4 a couple words and Zone 5 is difficult to speak at all. 
- 
 In theory you cannot stay in zone 5 for more than 5mins without throwing up

 Hi! 
 After the first time is vo2max calculated with all sports or just with walking and running?
- 
 @ink357 just walking and running activities. 
- 
 @hgavert hi there. 
 I was having same problem as you. But I have 2.10.26. Which is latest. But it was still not working. I did a hard reset today. And then a run. And now it’s working well. It is a bit of a pain doing hard reset and then setting up watch again. But worth it to get feature working
- 
 @ink357 hi 
 I asked suunto help centre about this.
 You need to do walk/run for calibration but after this your levels should change doing any exercise type.
 I have just done calibration today. So I have not tested this yet. But will let you know results mi week.
- 
 I’ve just made a 2 hours walk exercice but no vo2max estimated  
 It was a personalized exercice, do you think i have to calibrate with basic walk or run mode ?
- 
 @ink357 that could be the problem 
 I would do a hard reset. That’s what I did this morning then it basic run and got my fitness level
- 
 The watch is not a new, i wanted to try the new functions. Now i’ll make a hard reset with all new settings

 @Dimitrios-Kanellopoulos said in S9 Baro titanium not measuring VO2Max or fitness levels with 2.10.18 - is this a known problem?: To get VO2max you need good HR readings and a bit of effort (go to zone 2+ ) from my experience 
- 
 I think HR was good because there is no loses. I’ve made a hard reset… and lost my personalized exercises  How to add basic exercises in the watch ? Just make one and it will add ? Or i need to do that in SA ? Let’s try tomorrow ! 
- 
 @ink357 
 it’s a great disadvantage that sport mode customization is not stored and backed up in SA!

But today after my ride in bike mode no changes. It was a 1 hour ride and i went in the 5 zone of HR. Someone can confirm that the vo2max estimated will change after every exercices in all sports mode ?

 I just come from a walk exercise and the vo2max has changed… 
 Maybe that is just for for walk and run basic exercise. It make sense because the 2 exercises that gave me a vo2max estimated were with ascent, so the vo2max is so poor. To have good data the ground must be flat, no ?

To have good data the ground must be flat, no ? Correct. At least to have good/reliable estimation. https://www.firstbeat.com/en/consumer-feature/vo2max-fitness-level/
