In the Run window, choose Run raw log file.
You need to enable raw data logging in Options to create a log file. You also need to set a session folder, this is done when you start a run. The raw log file is stored in the session folder.
IS THE POLISH LANGUAGE AVAILABLE?
Greetings,
YourDyno 3.2.89 is out, with two fixes and one new language:
- In Load Control, brake ramp up would not start correctly when doing a Restart Run
- Loading a raw log file would only work with YourDyno disconnected
- Support for Polish language
Cheers!

Jostein,
I've asked this before but didn't get a reply. Even if I don't have the option 'enable raw datalogging' checked, it still saves all the .txt's
Is this normal? Basically it's always doing raw logs, the only difference is I can only open them when I do check the option
Tuners,
Minor release, YourDyno version 3.2.90. Just a bug fix for Load Control brake mode when choosing to regulate during start condition.
Cheers!

@tutuur, yes it always logs to file. I agree with you it is more logical to not do that if you turn off logging ;-). No harm to log though.
Looks like a lot of new nice extra features. I think I still have three very nice additional features which I like to include in the software.
- For the relay board it would be nice if you can include hotkeys for relay outputs so I can use the relays which start my fan and exhaust ventilation system. As an addition it might be handy to use roller speeds and lambda to stop and start the cooling fan and exhaust system so my relays. For example, the fan will start after seeing speed and the ventilation after seeing lambda. So adding function for the relays might help.
- Stored retardation run number to understand driving losses compared to other cars. might help by debugging low power outputs and or extreme drivetrain losses. Also doing runs with only rollers there should be a standard fixed retardation value for comparing the losses in the dyno itself to measure wheel power for example for motorcycles where you can't measure real losses.
- Also, some table where you can compensate for the non-linearity of the brake you add to the system. For example, to make PID control better. Making a table with different Voltages against output in % of the brake. When ending the run, I am limited to 50% braking power while 50% 2,5 volts is not doing much braking in my setup. While 80% and 90% is a big different. My brake system is very progressive related to its voltage.

Hello Jostein,
What is the status of the above mentioned improvements?
Jostein, is it possible to add a marker(s) in the graph window?
My customers aren't just looking for peak numbers but gains on the whole curve. Regularly I show them the difference in some rpm area's to graphically show them what improvements where made. Now I navigate with my mouse on different graphs.
Would be great if we can add markers with labels showing the values at that point of the graph 🙂
Tuners!
Software version 3.2.94 is available (beta). It introduces the following:
- Support for YourDyno Eddy current power supply
- Firmware 1.26 supporting the YourDyno Eddy current power supply
- Support for brake during Gear ratio calculation. This is good to load up the drive train and tires to get the most correct gear ratio calculation
- Support for 1 hotkey to set the gear ratio like this: In the Run window, push the Gear ratio hotkey to open the RPM setup and push the same hotkey to calculate and store the gear ratio and automatically close the RPM Setup window. Very convenient.
- Engine power calculation setup is now moved to Basic Dyno settings
- Change in the way Power Correction factor is used. It is now used like this:
- New: Engine power = (Measured wheel power + measured rolling speed losses) / (1 - Power correction factor)
- Old: Engine power = Measured wheel power * Power correction factor + measured rolling speed losses
- This is a more common way to use the Power correction factor. It will result in higher readings for the same power correction %.
- Improvement in Ramp up brake before runs functionality when starting in manual mode. Now brake keeps on after going past the start RPM.
- A few cleanups and minor fixes
Enjoy!
Hi,
The live graphs are basically made for steady state tuning, i.e. tuning of ignition and fuel at a certain RPM. You can also use it when adjusting PID parameters on the brake and I'm sure many other scenarios too, but steady state tuning is the most important usage.
For the comparison of one run with another, you need to watch the graphs in the results window.
Is this something planned for the future because i think it's quite usefull as well, would be nice to be possible to show the normal run page on one screen,and while making the run, plotting the data over the previous curve on a second screen
@svr-autosport, glad you asked...
This is indeed coming up. A much requested feature. The idea is as you say particularly nice if you have two screens. One will show the gauges and start/stop buttons, etc and one will show the graphs. Then the graphs update with the new run in real time so you can compare on the fly.
It requires software changes to get this done, but now that the power supply is finished this is next.
@admin nice to hear, planning to build single roller linked 4wd dyno, this was one of the only features i was missing.
Also i have another thing i was wondering about. So i got two options, permanent 4wd or switchable.
I was thinking of maybe putting a coupling in between the link system, pneumatic coupling as switch it with the relay board connected to yourdyno. But don't know if there is any provision for this in the software related to MOI. Because MOI will of course be different if you engage or disengage the coupling.
The reason why i would make it switchable is if you have a rwd car on stand alone ecu,a d you do steady state mapping, you don't have to care of the steering wheel if you only put it on the rear rollers. The other situation why i need the link is chiptuning of recent cars, for example audi's with automatic transmission are assholes to dyno if you test them 2wd, always have to pull fuses, so in this situation you need the link
