Computrainer, Macbook Air, Irregular Trainer Tension


(H P_Baxter) #1

I have seen a couple of upgrades since starting Zwift. The other day, the tension on the trainer kicked in on a downhill - it was the strangest thing. Did not think much of it until I tried to do a couple of FTP test. I could barely push the trainer at 265 watts for the 2 minute warm-up section. The setting for trainer difficulty is set to “off”. My other recent FTP tests were all over 200 watts for the 20 minute sustained effort. I doubt I could even hold 175 for 20 minutes today. I even uninstalled the software and re-installed. Same thing happened the 2nd time. . The tension on the trainer is consistent i.e. 2.2 to 2.6 as I always test it before plugging in and starting the trainer. I might be tired or over trained, but the whole thing just seems odd. Any ideas or thoughts would be much appreciated.

Issues like this many times are related to the DIN cable.  I’d do a visual check of it and power down the CT and unplug and re-plug the DIN cable in making sure it’s fully seated.
