Calibrating indoor trainer mode

[fishyweb]

Hi. I have a Minoura Hypermag turbo trainer, which I usually use on setting 4. I've selected "Minoura HYPER-MAG-1200R (4)" as my trainer in Isaac. However, judging by perceived effort, the PP is grossly over-estimating my power output when in indoor trainer mode, I'd say by around 25%.

I've done a FTP test (outdoors), and I'm now keen to be able to do some power zone-based training on my turbo, but this needs a good degree of accuracy to ensure I'm hitting the correct zones. Is there any way to tweak the indoor trainer mode to improve the accuracy?

Yes, two ways:

1) Set your trainer to a lower setting, such as hyper-mag 1200r (1)

2) In Isaac, use "Device/Edit Trainer Settings" to select your trainer, then use the Watts Adjustment slider to lower the watts reported at your usual speed. In the image below I've lowered watts by 25.1W at 20 mph. Make sure you use the "send to iBike" button afterwards to upload your changes to your PowerPod.

Fantastic, thanks John.
