Here's my situation:

Quarq S975 on my old Tarmac
Quarq Red22 on my Roubaix

Is there any way to calibrate/setup both meters so as to ensure they are accurately reading equally (within reason) given the same efforts?

Just wondering as similar watts on the Red22 seem much more difficult than before. It's like my FTP dropped 20-30 watts.

Thanks

have you checked the slope (static torque test) of your power meters?

yours is exactly the problem with "consistent but not accurate." if you haven't checked the slope on your quarqs, i suggest doing so ASAP.

IME, it was not uncommon for quarqs, esp older ones, to read a bit read high, but the bottom line is that while people should always care about accuracy and consistency in the long-run, your situation with 2 meters means that it is even more important immediately.
