    I am trying to use this upgrade with my iDash +Power. The trainer mode seems to be active, but the slider bar which is used to show the correct amount of effort, is not functional. The command slider moves based on the segment, but the actual effort is not active.

    I like the indoor trainer mode for the Newton, it makes indoor training a lot easier with less guess work as to the effort I am putting out.

    I purchased the upgrade of the indoor trainer firmware so that I could do power output contests at my expo booth. It works great actually as expected. No surprises, easy to install, easy to use and I switch the Newton from bike to bike (profiles) with trainer mode on. I believe the only confusion I had (and it’s not the fault of iBike) was that when choosing which trainer, I had three different CycleOps Fluid 2 trainers to consider, all with significantly different watts at 20 mph. So not sure how to ID the right trainer. I believe I picked the right one though, having ridden the trainer at each one and sort of “knowing” how it should feel compared to the watts displayed. Great investment! Love the Newton and the products that iBike is giving us!

    I ordered the upgrade even though my off-brand trainer isn’t on the list… Thought I’d be able to match it to some other model.

    That didn’t work, but it turns out to be very very easy to calibrate using a borrowed DFPM… I used a friend’s powertap wheel and followed the instructions in the Isaac software.

    Very cool!

    What an amazing gadget. I can’t explain how it works it just does… It is consistent and reliable. It took a while for me to be convinced that I could use the ibike on a trainer but it reacts quickly and detects even subtle increases in power. It has definitely helped me to train more effectively. The only downside is that I now know I wasn’t training hard enough before! So now all my trainer sessions will be true sessions of suffering. Overall very pleased with the effect of the trainer upgrade. On line support from John at VeloComp is very swift too. Extremely professional company.

    Down loaded the product into my ibike, chose my trainer, turned on the function and trained. So easy, my Border Collie could do it…..
    Great product by the way.

    Gives you a really clear way to improve on your turbo trainer. The results are consistent which is the most important thing. I found it accurate against my expected output and heart rate.

    I have a magnetic trainer with multiple settings. I simply send the setting I want to use from the Isaac Software and it works like a charm. I use a third bike with the trainer and the iBike to send the data to a Garmin so I don’t even need a mount for the iBike. I just stick it on the table or in my pocket and read the data off of my Garmin.

    I keep one bike on the Kurt Kinetic trainer and one for the road. Just switch profiles and Newton records my trainer or road work outs. Upload to Isaac and Golden Cheetah.
    I’ve got confidence in my power reading on the road and on the trainer.

    I have a Kinetic rock and roll trainer. Installed easily, works perfectly well, no concerns at all.

    The trainer key was easy to install. The Newton worked very well in trainer mode on the stationary trainer. If there was one thing that could be improved is with the automatic profile selection feature. Once the Newton senses a certain sensor code associated with the set on my trainer bike, I would love to have it also go into trainer mode automatically! An automatic trainer profile.

    I recently purchased the indoor trainer firmware upgrade for two of our Newtons in preparation for training on the rollers over the long Ohio winter. We’ve been using three Newtons on the road for two seasons and they are simply the best. They’ve replaced the rear hub power meters that we’ve used for years but were becoming much too expensive to maintain and too limited (no upgrade path, limited wheels, etc).
    The trainer firmware update was quick and easy and the Isaac software has an amazing number of pre-configured trainers and rollers and great custom configuration options.
