A bit more info...
I stepped back to 3.3.85 and the raw data import worked properly again. This version also has the updates for editing the gauge screen so it will be my happy spot for a while 🙂
@bendd and others reporting issues when re-running old raw files.
First of all, use csv format to store runs. I see some folks use log files instead, this is not the way to do it. Log files are normally just for debugging/testing new setups.
If you need to rerun a log file for some reason, then here are some tips:
- Gear ratio settings. Lately the variable gear ratio was introduced. If the gear ratio was calculated from OBD2 or CAN bus data during the run, then this will not work when you rerun the log file as those data channels are not part of the log file
- Auto zero load cell. This option is on by default and will re-zero the load cell when you open the Run window (if the RPM is 0). So results may be very slightly different if you re-run an old run. If the load cell is not connected, then you get wild numbers when re-running a log file. Turn the option off if needed
- The current Auto stop and Auto detect Early stop settings are used when reading a raw file. Change them if needed
- Log file format may differ slightly between versions. Csv files are backward and forward compatible
Don't hesitate to reach out when you have any problems to jostein@yourdyno.com. To be able to help I need 3 files:
- Your settings file (Options->Backup options to file)
- The log file
- The corresponding csv file
Limit the mail to include these 3 files of a single run.
Folks,
YourDyno version 3.3.93 (beta) was released today.
Changes:
- CAN bus improvements when using the bus heavily (faster implementation). The firmware needs to be updated to take advantage of this improvement (Options->Firmware upgrade)
- Some Auto start/stop improvements
- Noise filtering. In version 3.3.91, some channels had no noise filtering, for example for the brake channels. They now behave like other channels where the user can choose the noise filtering level. For the brake channels (Brake%, Kp, Ki and Kd etc), it is recommended to turn filtering off to better monitor the brake performance, but this is now up to the user. This is done in Options->Visual styles
- The PTH200 plugin for external weather station (mostly used for older YourDyno units) now have the temperature, pressure and humidity data channels available for gauges/graphs/tables
As always, let me know of any issues (jostein@yourdyno.com).
Hello,
Is there a switch somewhere to do away with the ECU Master channels popping up in the gauge selection menu and in the stored csv's? I have not defined or activated them in the CAN Tab so I wonder a bit why they keep being there. 🙃
@rub87 the channels will pop up if you open an old csv file with those channels defined. They go away again when you restart the program.
Hi folks,
YourDyno version 3.3.95 (beta) was released today.
Changes:
- Better auto-stop for ramp up sweeps
- Better handling of changing name of a data channel. Earlier, after a data channel name change you could for example get 2 gauges for the same channel until YourDyno was restarted. It could also increase the CPU load until the next program restart
- Fixed bug when loading a raw log file (auto-stop would not work properly)
- Improved handling of Auto zero (for water brakes) when the valve is not connected or powered off, or when the Auto zero is not configured correctly. Earlier, if the auto zero failed and you cancelled the action, the gauges would all be placed in upper left corner and the gauge layout would be lost
- Improved CPU load somewhat
- All features of the UltimateV2 are now fully supported
- Added dbc files (CAN bus configuration files) for Holley Sniper V2 and HP Dominator and Terminator X
Enjoy!
This is probably the last update before a large, exciting release, so stay tuned!
Any issues, let me know.
Thank you Jostein for your hard work and dedication. I'm very excited for the release! 🙂
Hello,
i have a Problem. I want to switch on and off my Fan in the Front of the Dyno.
At the Plugin "Relay Control" i give the Port 1 a Hotkey and saved this.
This all works perfekt, when the Side is open. Then i can switch on and off over my remote Controll.
But when i close the Side were you can switch these Settings, then it does not work any more.
Software ist 3.3.85, i tried also the new 3.3.95, same Issue.
By the way: At 3.3.95 when the Language is set to German, at "Settings" the Point "Engine Power Correction" will not be shown.
Greetings Markus form Germany, Dynokraft A200 4WD
I have issue with latest sw versions. We use eddy current brake system, and test from aproxx 2300rpm -> 1200rpm (engine). When reaching end of dynorun (1200 rpm) yourdyno just locks up this rpm and keeps loading engine until i leave the dyno run window.
This has just started on latests sw versions. all other version would automatically turn off eddy current brake automatically when reaching end rpm.
The brake regulator continues to operate even after the run is complete. This is to avoid sudden acceleration when the end RPM is reached, if the brake is immediately turned off. When you go off the throttle, the brake % will reduce, since Engine RPM drops, but in your case, not fast enough.
You can control the brake behavior after the run is complete using the "Slow down rotation when run is complete" functionality.
If you set Slow down to 25% until 1500 RPM for example, then it will hold minimum 25% until 1500 RPM, after which it turns off the brake.
@maxximumboost, I recommend using the KmTronic usb relays, they have much better support in YourDyno.
Hello,
so the Internal Dynokraft Relais i can not use???
Is this not only a Bug? Because when the switching Window is on, then it works perfektly.
Only when i minimise this window, then it dont work.

Folks,
YourDyno Software version 3.3.97 (beta) was released today.
Changes:
- Fix for auto cut graphs at max RPM for runs not reaching the defined end RPM of the sweep. This was thought to have been fixed in the previous release but was not
- CAN Out now supports both CAN Normal and CAN Extended
- New option in the PID regulator. See Advanced... under PID Control loop. The default operation of the derivative component of the PID is to resist acceleration and deceleration, irrespective of the Engine RPM vs Target RPM. This new option lets you choose the more traditional derivative behavior where it uses the changes in the error signal (Engine RPM - Target RPM) instead. This approach can be better in some setups, so you can try it out if you have control issues. It is more sensitive to noise on the RPM, so there is a filter there.
Hey folks!
A major new release of the YourDyno software is now available. It is called UnaVision and includes a lot of new features.
The biggest change is that all runs and sessions are now stored in a database. The dyno settings are stored in each run, and there is support for profiles, there are templates, etc.
Make sure to manually backup the options from the old YourDyno installation and read it back to UnaVision.
The software is presented in this YouTube video: YourDyno UnaVision dynamometer software
You can download it here: https://yourdyno.com/UnaVisionInstaller_4.0.31.exe . It is a free upgrade for all. We hope you like it!
