It's official, TTS news update indicates Bushido firmware 5.13 is now available for update.

I will dowload it and try it later in the Fall. In the meantime, if anyone tries it, it would be nice to get the feedback.

I installed it shortly after posting and then did a short 30-minute training in stand alone mode. Good news is the intermittent Pause popup that the BETA test group observed with 5.10 have been corrected and once paired and calibrated with my SRM, the motorbrake seemed pretty stable with a few intermittent high/low surges in resistance.

Problem I found was that in stand alone mode, if I exited a trainng program before completion and immediately started another, after the countdown, the motorbrake immediately started setting resistance such that power values on Bushido were 15-30 watts higher lower than those from my SRM as displayed on a Garmin Edge 500. Stopping the program and then going re running the Bushido Power Meter calibration (Settings -> External Sensors -> Power Meter -> Calibration) appeared to resolve the issue but as soon as I stopped the program before completion and started another, Bushido again was setting motorbrake resistance levels for much higher power levels than indicated on the handlebar controller.

I have just installed 5.13.

No problems except that when I started a RLV there was a "pinging' sound from the brake. This lasted for about 40 seconds and then died away.

After about 28 minutes there was a "bong" "bong" noise from the brake, I eased off my cadence a bit and the "bong" stopped. After 33 minutes it started again and got more and more persistant and louder. I aborted the ride.

I checked the brake , it felt quite cool.

Nothing like this has happened before, I have used the Bushido since August 2009.

Any ideas anyone? I'll try again tomorrow and will report if anything untoward happens.

I finally tested the new Bushido software. It works OK, but there are a few problems that are still there. There are the occasional instabilities where the resistance increases for no reason. Also at the end of the workout, the box that asks whether or not to save the session does not detect the brake. Fortunately there are posts that indicate how to work around this problem. I wonder why Tacx has not solved those problems. Unfortunately, with the instability of resistance, we do not fully benefit from this improvement.

I think the instabilities in motorbrake resistance are a combination of very minor ANT+ signal interference as well as the Bushido exagerating the naturaly stochastic nature of power measurement/output.
Also at the end of the workout, the box that asks whether or not to save the session does not detect the brake.

See my post in the Ride not letting me save thread.

I know it is probably hard for you to explain your point, I am not sure I fully understand your post. Instead on unplugging and replugging the dongle, did you solve the problem by simply repointing the dongle in a different direction?

I won't know whether or not reposition the Ant+ USB makes any difference until after test this with tomorrows training.

Now have to agree that this looks like a software defect possibly with common/shared code between TTS 3/4. With the ANT+ USB stick positioned ~3ccm from and pointed directly at the underside of the Bushido handlebar controller, I did percieve a very slight improvement in motorbrake response during my training session but that did nothing to resolve the issue with not being able to save the ride after completing the training program. So has anyone actually reported to Tacx or have we just posted to the forums about the issue?

I am not aware of anyone reporting the problem to Tacx.

Hello,

I have attached Quarq S975 with TTS 3.12. The main computer has software 5.13.
When I run the RLV, Catalyst, I get occasional pause message, brakes react correctly and reduces drag.
But very often I notice while studying the graph cycling or in Analyzer that power, heart rate and speed dive to zero for a second and then returns to the current (correct) value. The brake does not respond to this luckily. But the problem is that the averages (power, heart rate and speed) is wrong in the Analyzer.
When disconnecting Quarq then it's OK. Generally, I think the brakes react properly as road profile.

regards

This is a known and persistent bug and appears to be due to a temporary lack of acquisition by TTS of the ANT+ values.

Report it to Tacx and hopefully it will be corrected as was the false overheating warning in the current TTS release.

Thanks Kevin, (additional) info much appreciated!

I have exactly the same configuration, Quarq S975, Bushido with firmware 5.13, TTS 3.12. I have tried multiple times to do RLV, RLT and VR with the Quarq connected to the Bushido head unit, but the connection is erratic and I was not able to finish trainings. I have now disconnected the Quarq from the head unit, I am using the power calculated by the Bushido and not the one measured by the Quarq, everything is now back to normal. And by the way I have measured the difference between the Bushido brake and the Quarq, if you do the setup correctly it is a negligible 1.5%.

Martin that statement is only my thoughts on the problem, I have no confirmation from Tacx on this. Unfortunately beta-testers are often not in the loop either.

Has anyone else noted that when the Pause-Stop Training pop-up shows that the heart-rate displayed is not the current value. By the end of the pause interval the heart-rate updates to the correct value.

Does the Quarg suffer from more connection problems than a Powertap? Anyone compared the two?

Currently with my Powertap the issues are still the irritating Pause pop-up about every 5 minutes and the occasional loss of brake connection, which is much more frustrating (even with the Suunto stick and close proximity of the brake to the stick). I am checking the USB sleep setting currently. First one and a half hour run was fine.

I have a Suunto MoveStick Mini on an extension cable clipped to deraileur cable so that the stick touches the underside of the Bushido Handlebar controller and still get an occasional pause popup when training connected to TTS. Now I cant comment on the Powertap versus Quarq, but with my SRM, although I typically am limited to 45-60 minute Catalyst training sessions, I have noted HR being a bit out of sync on the rare occasion i get the popup. This also has me wondering if these 'sync' issues are what causes the lack of stability of the motorbrake resistance while paired with an ANT+ powermeter?
