I have setup zwift with my Elite Crono Fluid turbo and Garmin speed/cadence sensor it works fine - however, it reads my speed and the power (I don’t have a power meter, but I don’t need one to know) watts reading more than it should.
I’m sure there is somewhere to configure height/weight/bike size etc. could someone point me to this and any other tips on calibrating?
Since the Elite Crono Fluid is compatible with Zwift the reading should be reasonably accurate, but bare in mind it will never be as accurate as power meter or high end trainers.
You can change the weight and height in one of the following:
I have the Elite Crono Fluid and Zwift recommends using L4 - however, I felt that this was not correct and sure enough after installing the new Garmin Vector 3 power pedals I can now see the difference between the real power readings and those predicted by Zwift Power (ZP).
I put my Elite Crono Fluid on Level 1 and for the first 5mins found the ZP readings to be higher than the real power readings:
ZP=150w / Real=140w
ZP=250w / Real=200w
ZP=350w / Real=265w
But as time went by the resistance seemed to keep increasing so after about 30mins the real power readings were becoming higher than the ZP readings (but only at the upper end!):
ZP=150w / Real=100w
ZP=250w / Real=265w
ZP=350w / Real=420w
After 40mins:
ZP=150w / Real=150w
ZP=250w / Real=320w
After 50mins all real readings were higher than ZP:
ZP=150w / Real=175w
ZP=250w / Real=340w
So basically the resistance of this turbo increases with time and in a non-linear way.
Another day I recorded the real power readings against a set speed (recorded by a garmin speed sensor) and got the following results as time progressed:
35kph:
170w after 5mins
175w after 10mins
170w after 20mins
186w after 30mins
190w after 40mins
194w after 50mins
280w after 2hrs
40kph:
200w after 5mins
213w after 10mins
215w after 20mins
220w after 30mins
246w after 40mins
250w after 50mins
400w after 2hrs (yes 400w!!)
50kph:
276w after 5mins
300w after 10mins
315w after 20mins
380w after 30mins
430w after 40mins
460w after 50mins
In summary the power calculated by Zwift (ZP) is not very useful, especially when racing and you’re trying to hit those higher numbers!
