FTP Test

  • I bought a FE-C trainer (Tacx Vortex) and i'm setting up everything as needed. No problems so far, MaximumTrainer controls my trainer perfectly well. On my former trainer my FTP was around 230W but I noticed rapidly that this was to high for the Vortex. It's more like about 200W (not good for my ego ;-) but probably closer to reality).
    Anyway, I performed a FTP Test today (never done this before on MaximumTrainer) and noticed something that I consider an error. The FTP test is setup with a 20min interval at FTP. I think that you should use FTP*1.05 (FTP/0.95 to be totally exact) for the target in the 20 min interval. After the FTP test, you do calculate the FTP result as 95% of the 20min interval average, and that is correct. Can you consider changing the target to make sure that motivation is high enough for the test?
    I'm planning another test later this week to correctly identify my FTP. For now I scale to 105% just before starting the test interval.
    I also noticed that you quit Erg-Mode automatically when the test interval starts. That's really nice, it makes sure that one can really go all out! I tend to follow the target during the first half and if I feel good, crank up during the second half.
    Winter is just starting here in Belgium and you'l see my upgrade coming shortly. 6 months should do for me, I rarely use the trainer during the active season.
    It's nice to see that you continued development during summer. I have to checkout the new features.

  • Hey Claude,
    Glad to see you here! Congrats on the FE-C Trainer, I heard the Vortex is a good one.
    I had the same thing happens to my FTP when I changed trainer. With trainer control, the resistance feels much harder. I had to lower my FTP around 20W to be able to do the same workouts.

    You are correct for the 20min interval. The result is 0.95 of the 20min section so if you want to keep the same FTP, you should be going at 105% your current FTP. I will update the target in the next version for 105% instead of 100%. For now, you can just see this section as a target but going over is not a bad idea if you want to raise your FTP.

    Thanks for the good feedback! I did put a lot of time this summer on it. For now I will have to put less with other commitments I have.
    See you!

  • Hey, I'm a new user of Maximum trainer, and really satisfied by this tools. Congratulations.
    My question concerns this FTP test and configuration of trainer.

    I own a Direto elite FE-C trainer. If you realize this test, it's in order to know your FTP, so I assume you de-activate the FE-C functionnality and use your trainer as a powermeter, andtry to reach during the 20mn test, the best and regular power you can.

    If I think my FTP is 200W (and have configured Maximum trainer like that), and let the FE-C functionnality, the 20mn test wil adjust power to 105% (210W), so I will produce 210W and find a FTP of 200W => logical!

    Can you please that trainer has to be recognised as a powermeter, and not as a FE-C trainer?


  • Hey Albert, sorry for the delay

    Did you try to do the FTP test with a FE-C Trainer.
    It should disabled erg mode or stop controlling the resistance when you are in the test interval.
    Let me know if you run into any issues.


  • Installed Maximum Trainer and I must say im impressed with it. It works perfectly with my Stac Halcyon.

    The FTP test is confusing. It states to follow the green bars, which offcoarse is false. It would be better to mention that you have to cycle the 20min test part at the max you can sustain. So dont follow the green area for that part.
