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.

@admin Awsome update live the 2 screen set up 👍

Greetings tuners,

Software version 3.2.79 (beta) was released today. It provides some nice features 😎 :

• A much easier way to install and de-install plugins. You now do it via the installer where you select which plugins you want to install. You can also open the installer again and remove the plugins you want to remove
• Wheel HP and Wheel Torque are shown in the table below the graphs if only wheel HP/Torque are selected
• Support for 4 brakes (4 load cells) with 2 RPM sensors. This is used for very large dynos that require multiple brakes per wheel/axel. As for a 4WD hub dyno it requires 2 YourDyno boxes
• Ability to span the Run window with gauges over several monitors. Just drag the window to fit, arrange the gauges. Setup is saved automatically
• Ability to play back a raw log file in real time. With possibility to stop recording at a certain point in the run
• New plugin format such that plugins can read and respond to data from other plugins

Enjoy!

@mikecarr4, I wonder if the save issue can be a permission thing. Is your user admin on the PC? I have tried to reproduce it unsuccessfully. 

Also, the torque arm length doesnt seem to save occasionally in version 75. I have gone back to 59 and all saved now. This is probably not something people change very often.

See video.

Have been getting this occasional error message through with the latest version has anyone else had this?

@admin

Thanks for looking into this, I will do my best to test this today with the changes you've suggested.

Hello, yes that will work. 

Hello. Latest firmware will work with old software 3.2.59 ?

Regards

Guys,

There was a bug in the latest firmware 1.24 which would make RPM1 hang up in some special situations, as was reported here (thanks!). 

Please upgrade to Software version 3.2.76, then click Upgrade firmware. 

Happy tuning!

@admin, I have created a good log file now.

Attached .jpeg here and I am sending the raw on e-mail.

Guys, I have kept it running now for hours, I am not able to reproduce it. Can you send a raw log file with the issue to jostein@yourdyno.com please? Record when both hubs/rollers are spinning or at least when RPM1 is spinning. @aslot it would be good if you could capture the moment it stops reading RPM1. 

@aslot  Hello,For what its worth I too am having issues with my RPM1 disappearing after a short time. I have only one RPM input, a GT101 sensor (engine dyno). I too have to do more testing but I do have a good RPM signal at the Your Dyno plug when operating correctly and also after the tacho stops. I had no RPM issues prior to this. I too updated to the latest version before this happened. All other gauges keep working without fault when the RPM stops. It does appear to be a software or box issue.

I have now done some more testing.

At first start(system and PC-boot) I have RPM1 reading, after around 30s with spinning hubs the reading stops and only shows 0rpm.

If I switch the RPM1 and RPM2 connectors at the box I still only have RPM2 reading.

If I disconnect and connect the USB to the box I get RPM1 reading for around 30s again same as at first start.

I have tried to change all the filter settings but nothing works.

@admin, Roller1 RPM gauge shows 0RPM all the time, Roller2 RPM gauge shows the correct RPM. The total RPM(Engine RPM gauge) shows around half the real engine RPM.

The sensors are working and the gear ratio is correct, if I switch back to 3.2.59 I have RPM reading on RPM1 and RPM2 gauge and the correct Engine RPM.
