tacx fortius glitches

I recieved a tacx virtual reality trainer for xmas from my good lady wife , i've been pretty excited about using it to relieve the boredom of turbo training , my alpine classic dvd arrived yesterday -
i've downloaded all the software etc and on commencing a ride up alpe d'huez or any of the courses the resistance becomes very jerky immediately with a few seconds of being able to pedal ,it is impossible to ride at all, then intermittently putting the breaks on ,also the wattage figures aren't showing up .....any advice

I had a similar problem at first, the cadence magnet on the crank does need to be as close as possible to the sensor without them making contact. That fixed my problem anyway and the whole thing has been flawless for about 3 months now.
Let me know how that goes, about time I stopped lurking here and tried to help
Its a video codec which should support everything needed without having to adjust all the settings.

Am i expecting too much, or do others have a realistic ride with smooth pedal strokes and linear resistance within each pedal stroke whatever the gradient.

Also make sure you have enough contact between roller and tyre. The recommended procedure is to slacken off the roller, move the lever into the engaged position and wind the knob until the roller just touches the tyre. Disengage the roller again, then do 3.5 turns of the knob and re-engage the roller. It will need a fair amont of force to engage the roller when correctly set. I also put around 100-110psi in the tyre.
As mentioned above try with different tyre pressure and the pressure of the actual machine on the tyre. nothing too outrageous but just subtle adjustments as the way it is now is not correct.
let us know if you have any success or not..
Alpe D'Huez TT is one of my favourites, and do that as my Friday torture session most weeks, it's a good way of measuring progress for me.
Are you on a Fortius or I-Magic Inseine?
My mate who fancies himself as a bit of a TTer came up to challenge me on the AdH TT a while back, and I forgot to set up his profile, so he raced on mine. He came in at 51 mins, and was very chuffed with himself, until I noticed he weighs nearly 2 stone more than me, so set him up a profile of his correct weight. He reckons I have the easy life now, after re-trying it at his correct weight!

Bob, there is a known (but as yet, not admitted) issue with a batch of Fortius machines where the wires inside the round plug that connect the silver powerbox to the trainer were no sufficiently tightened at manufacture. Yours may not be affected but i would advise you to check.
I had 2 loose wires and after tightening have never had any problems. Prior to this i was getting random locking of the motorbrake while riding and also finding it very difficult to get going in the first place due to jerkiness and much resistance from the machine.
Prior to doing this I would recommend running the Tacx system test which should be installed on your PC, to check that all the hardware is functioning properly - just in case you have a faulty cadence sensor.
I can send you a pdf instruction file (re. loose wires) from Tacx support if you wish - PM me.
