Greetings tuners!
Software version 3.01.43 was released today. It has a number of important improvements! Here is the list:
- Ability to compensate for inertia effects for brake dynos. This is an important feature, especially for brake dynos with heavy rollers. During acceleration, power is used to accelerate the inertia, and this needs to be compensated for. Power is now calculated as the sum of the power measured by the brake and the power calculated from the inertia acceleration. The setting is only helpful during acceleration runs, in steady state runs it does not matter.
- Ability to calculate drive train losses during retardation. This works for inertia dynos, and also for brake dynos with sufficiently heavy rollers. It works by measuring the deceleration during retardation. Using the deceleration and the Moment of Inertia of the system, it calculates the torque loss at each RPM. With this option enabled you get both Wheel HP/Torque and Engine HP/Torque. Wheel HP/Torque is what is being measured, Engine HP/Torque is calculated. Do you wonder how what the MOI of your system is? You can try to calculate using MOI calculators online, however, there is a nice trick to measure it using YourDyno. I will explain in a separate post or help section.
- A Data connection monitor in the Run window. The status is color coded, and should remain in the green with only momentarily showing yellow/red status.
- Improved brake control performance. You may need to increase the PID parameters compared to before.
- Improved print quality.
- Improved IIR noise filter (keep it on!).
- Keeps all user settings, like calibration data, when installing new versions of the software (finally, sorry it took so long!)
- Automatically alerts you if there is a newer version of the software available.
- A few other minor bugs and cosmetics corrected.
Enjoy!

Jostein
Hi folks,
UnaVision version 4.1.16 was released today.
Changes:
- Firmware update for YourDyno Standard v5. Now you can reboot the PC without disconnecting and connecting the YourDyno box. This fix was long outstanding and somewhat annoying. Go ahead and update at Options->Firmware upgrade
- Similar fixes available for the Ultimate boxes
- Fix of locked graph tabs after a run. This would occasionally happen, in particular on slow computers.
- Now the Results tabs show the selected data channels even if no run is loaded, which is similar to graph behavior
Thanks for the feedback, and as always let me know of any issues at jostein@yourdyno.com
Some great improvements there. Thanks Jostein.
Hi folks,
UnaVision version 4.1.15 was released today. It contains a number of improvements, so an upgrade from 4.1.xx is recommended.
- Higher resolution, faster graph printing. Earlier it would take a while to generate a printout, plus watermarks would not always be placed in the same place on the print as on the screen. This is much improved now
- Lower graphics processor load for the graphs. This is mostly noticeable on lower spec computers
- Ability to enter Comments before the run is done. Earlier comments had to be entered after the run
- Ability to modify the run time/date
- Bug fix in the moment of inertia wizard
- A number of other small cleanups and fixes
New functionality:
- There are now two different Moment of Inertia wizards
- The existing two coast downs method as before for high inertia dynos (chassis and some hubs)
- Oscillation method (new). This method makes the dyno/engine oscillate around a certain RPM, and calculates the matching MOI such that the power/torque vs RPM follow the same path going up as going down as closely as possible
Feel free to play with the new MOI wizard. A video will come soon explaining it better, so stay tuned!
As always, any issues let me know at jostein@yourdyno.com
Cheers
Hi everyone, is there a working German version of the UNA software yet?

Folks,
UnaVision version 4.1.12 was released today (beta).
It is a cleanup release, no new features. The following are changed:
- Further improvements to Font scaling. If you want larger fonts, control the scaling by right clicking on the Windows desktop, then select Display Settings, and select Scale. Use this instead of Options->Font size which will be depreciated
- Fixed a bug in the MOI Wizard
- The results Splash screen will now always be on top of other windows, plus there will only be one Splash screen at any time. In case you have Auto close turned off, earlier you could have several Splash screens from earlier
Enjoy, and as always report any issues to jostein@yourdyno.com
The font sizing is very cool as I over the 50 😀
For us old guys with sub optimal vision, this is what I do...
I run a little program in the corner of the run screen called Magnifixer. In this window it shows the area around the mouse pointer magnified by the selected amount. I use 3x or 4x.
This allows me to make changes to the run screen on my 43" tv/monitor from inside the car. Without this, I cannot read the little numbers from the driver's seat.

Folks,
UnaVision version 4.1.10 was released today (beta). Here are the changes:
- Ability to select theme when printing. This is nice when printing to PDF, or if you want more colors on your paper print. Select the printer theme under File->Print page setup
- Ability to reduce computer load by running slower update rates on the graphs. The new graph library is GPU hungry on full throttle, so for slower PC or PCs without a graphics card, select "Reduce computer load" here: Options->Dyno type and profiles. Update rate is max 10Hz with this option, but this still looks good
- Exiting UnaVision was slow on some computers. This is sped up now
- More fixes when running different windows scaling from 100%
- Fixed a truncated digital gauge for large numbers
In addition, it is now possible to run UnaVision in 32 bit mode. By default, UnaVision is now running 64 bit, but for some old plugins (VM167 for example), 64 bit is not supported. Both 32 and 64 bit are installed. To force 32 bit, change the UnaVision shortcuts to open ...\x86\YourDyno Unavision.exe
Enjoy! And let me know of any issues at jostein@yourdyno.com
Folks,
New UnaVision version, version 4.1.09. It is focused on printing issues and windows scaling:
Changes:
- Better printer support: Earlier, printing would not work on some PCs. If the printer driver acted up, it could even prevent the program from starting
- Table printing made prettier
- Windows scaling was not supported earlier. Meaning if you ran Windows with for example 125% scaling, the graphs would change size and the dashboard would look ugly. Windows scaling is now supported.
As always, let me know of any issues (jostein@yourdyno.com)
Enjoy!
Hi folks,
UnaVision 4.1.05 was released now.
- Fix: Sometimes runs would not be stored and results would be 0.00
Thanks for reporting!
@bendd, I tried to reproduce your db issues, but it works here. Contact me directly next week and I can login with you and check what is going on
.......and also if I enter something into the 'Comments' field on the DB screen and exit the program, the comments are lost when the program retarts.
And a question. Is it possible to edit the 'Created On' date on the DB screen? Some of mine are incorrect and I'd like to correct them so I can look back through runs in the correct order to review developent of particular cars over time.
Very minor issue Jostein, I get an 'unhandled exception' error that crashes the program if I try to add a custom column name to the database screen/tab.
Hi,
Quick update that fixes a printing issue and the application not starting on some computers.
Thanks for the feedback.
@doctor-542 please contact me at jostein@yourdyno.com or Whatsapp +47 4840 1279. Install Ultraviewer. I will login to your computer and see what is going on.
Same if anyone else has install problems, contact me directly.
