Hi Everybody,
I already changed my battery covers, updated the firmware version and changed my right pedal scale factor according with my weight calibrations tests.
It does work much better now, although I have to clear batteries with baby oil monthly to avoid power drops.
I feel that when I am climbing out in mountains and standing at very low cadence, my power readings are too low according with my speed and force applied. So I made some tests to compare with another power meter, I tested with Power Tap P1S and my feelings were ok, is lower than PowerTap pedals for same speed on the same hills.
To make a better test, I have used my Trainer a the same time with Vectors 3... for cadence and power readings compared with Tacx Neo... Ohhhh It is so variable for low cadences (< 70 rpm).
Below 70 rpm, when I ride out of saddle (steeper mountains of Zwift), power difference is big and always Tacx Neo is higher than Vector 3 for 10 watts or more, some times 20!
Between 70 and 90 rpm, works very good, power difference is low, and very similar between both. (between tolerances of both devices ~2%)
Higher than 90 rpm, Vector 3 is a little bit higher than Tacx Neo.
I must say that this happens always in free mode (NO ERG) and in workouts with ERG mode active, differences between both at ERG mode are even higher!
I did a FTP test with both systems at the same time, and doing it at cadence bewteen 70 and 90 gives me similar results, but doing it with some minutes below 70 rpm with steeper rides gives me a FTP difference of 8 or 9 watts between both and the Vector value is the lower one compared with the previous FTP test.
Why is this happening? Dome somebody else have this same issue?
Thats mean, Vector 3 FTP test for cadence below 70 rpm (some parts, not full 20 minutes range) delivers a result of 8 watts lower than same Vector 3 FTP test with cadence between 70 and 90 rpm... This cannot be a good working right?
