Agree. I have four power meters from three different brands installed to my bikes and the power figures from vector 3 double sided pedals have always been in line with othe PMs. I would not trust the power figures of a trainer that much, although I know there are some trainers that are pretty accurate.
Have you tried the torque test here

My Vector 3 pedals were pretty much spot on.
I used 6 kettler weights Of 2 kg with a belt. Total weight 12,05 kg. It gave me 25,34 as a number. I did the test oncebecause no more time.
12 kg9,810,1725 is about 20.
So 25,34/20= 26% difference
Is the “total mass” you used measured or assumed? By assumed did you just say 6x2kg=12 and belt is .05kg so 12,05kg system. Or was the 12,05kg from weighing all 13 items at once?
Yeah weight it all together on a proper scale.
The weights of kettler were as expected spot on. The belt weight less than 100 grams.
What freightened me most is that het number is higher and about the percentage I think it is off.
(Old ftp 233, new obtained just by doing an hour ride 278w).
I will however repeat this test once I have time and also do a climb test like the other guy suggested. (I live in Flanders so not that easy to find)
I can use the vector to train since I now know that 290-300 w means suffering and probably breaking when sustained too long. And 240 is quite chill and good for a long ride.
But I want to do an effort to be sure that the numbers are really correct (since that is what I paid for).
I keep you posted.
I have Garmin Vector but S/left leg only version and a lot of comparisons to other power meters because I have a few bikes with different power meters
My Garmin Vector is pretty close to Giant Power Pro but not to close to Stages L and definitely not close to Tacx Flux 2 with I’ve got. Garmin Vector and Giant Power Pro (dual side) difference is only a few watts and for me is ok to use both of them for training. The numbers are close to Favero Assioma Uno witch I tested. My Stages shows always lower numbers and the difference is about 10-20 watts. My Tacx Flux 2 show big difference compare to Stages (much lower numbers) and the difference is not consistency, but those numbers are huge like 20 watts on 200 watts point and 30-40 watts on 300watts intervals. So I use power match and Stages on turbo trainer (I use for that my old road bike with is turbo trainer only) with FTP tested on this setup. On outdoor rides I use different FTP anyway and I tested it with my Power Pro but I use the same numbers with Garmin Vector.
Your weight is 83kg so FTP 280 sound realistic to me. And, from my expirience, Garmin Vector are pretty accuracy. To validate it you can do longer climb and compare VAM with VAM/Power calculators. It’s not very accurate but this method is accurate enough to valid this huge difference between your turbo trainer (230) and PM 280-290.

Hi, I did a small hill
Can you see if that is possible?
Thanks
I checked a ride I did yesterday on Zwift. I have Zwift using power from my KICKR but keep power with my Vector 3 pedals on Garmin Connect. Zwift/Kickr average power was 194W and V3 average power was 195W. I di notice that the Kickr tends to record higher power for the first 10 minutes I think until the KICKR warms up.
Mine does the same. Once it is warm and I calibrate, my kickr and Vectors track very closely.
Hi, I did my fifth ride with the new ones.
So far I think the conclusion is that my tacx vortex gave too low numbers.
I have switched the pedals for some outdoor rides and also indoor.
I had the feeling that by torqueing the pedals a bit harder my numbers were a bit lower but I will retest this in the couple of weeks.
The vortex seems good so far.
Definitive conclusion will follow in some months
I mean the vector seems good, typo
