My Kickr Core power meter reads 4% greater than my outdoor bike. Is there a way I can calibrate TR so my power is reading 4% less? Right now I’m jacking up the power on TR to match my outdoor metre but in doing so it’s artificially inflating my FTP.
Thanks in advance!
Use power match and it will control your trainer based on power from the pedals and not the trainer then you won’t have any inconsistencies between indoor and outdoor.
Except the assioma’s are on “the outdoor” bike. Not the trainer. And no if I wanted to swap the pedals every time I rode indoors I wouldn’t have a dedicated trainer bike.
Ah ok. Fair enough, I thought as you dual recorded you were using the power pedals all the time.
Buy another set of pedals 
Maybe try advanced spin down on the Kickr, it might bring it closer into line. If you can get with say 1% it’ll matter less
Is it outside of tolerance? Warranty the pedals or the trainer.
Have you tried this? My Kickr Core and Assiomas generally align pretty well but when they seem to diverge a bit, the factory spin down has helped.
Yes, did a spindown and calibration on KickR, Assioma’s and TR again yesterday. It’s been around 4% since I first got both devices a two years ago.
Wahoo will say it’s the pedals, the pedals will say it’s wahoo. lol. Either way, 2% on each is within tolerance, so the argument could be one reads 2% low the other 2% high. It doesn’t sound like much but 287w outdoors reads as 300w indoors,
I would think when you start trying to manually fix that disparity, you might be opening up more problems than what it’s worth. At least its consistent, but it’s still annoying.
I mean right now I’m just increasing intensity on indoor workouts by 4% but then it throws of the AI as it artificially will inflate my ftp. Not a deal breaker but I figured there might have been a simple work around. like a power offset on tr or wahoo.
It seems at this point it isn’t known which is the more accurate. To match them, the Assioma pedals can be adjusted up/down in their app (and l/r individually) pretty easily to match the trainer. In a perfect world, the pedals would be reading a few percent higher than the trainer due to drivetrain losses.
There is unfortunately no way to do so on TR other than using PowerMatch. You mentioned that you didn’t want to swap the pedals, but perhaps you could put your outdoor bike on the trainer so you could take advantage of PowerMatch? No swapping pedals then 
(though I do understand it defeats the purpose of having a “trainer bike”).
Otherwise, I think your best bet will be to go with what @Saddlesaur proposed above. Changing the power of the pedals themselves would then affect your outdoor riding too, though, which is worth considering.
I totally would if the pedals read higher than the trainer. But for whatever reason the thought of raising my ftp 4% on my roadbike makes me feel like a fraud. lol
Epic username btw. 
Yeah, for all the faffing I’d sooner just ride outside. That and I have 11 speed on the trainer and 12 speed on the roadie.
FWIW: For PM testing/comparisons, I’ve run a different speed cassette on the trainer than what the bike had. Running in ERG mode I only needed one cog to line up, typically near the middle of the cassette, as I didn’t do any shifting. I adjusted cable tension or micro adjust to get the RD to perfectly line up with that one cog.
