Hi.

 1. Why is it that all calibrations is lost when you update firmware and software?

.2 The Menu for entering roller diameter is lost?

3. It states "engine hp" on the graph? How do i change it to wheel hp?

1. Thanks it would be awesome if you could add the print out list

@stvdrag225, yes that "C" displayed with imperial units selected is a bug, I will fix it, thanks.

Regarding the print out, it is not possible directly. You can open the .csv file in excel though and do some data filtering if you can and produce it. But there is no automatic way to do that today.

Hi,

Walter: The "Use brake to slow down rotation when run is complete" only kicks in when the run goes into "Done". When you have compensation for frictional losses enabled (like you do), this happens after the retardation run. So it does not mess up the retardation run. If you don't have that frictional losses correction option turned on, "Done" means when it has reached end RPM. The system will also in that case wait until the brake power is less than the set retardation brake force before jumping to the retardation force in order not to risk over revving the engine. 

HondaRulez, could you just set the brake/RPM options again after installing the new version? 

radics1, I see one way this can happen. If you have Manual mode on, Auto start/stop on and correction for frictional losses is on. Then if the engine RPM drops below the start RPM it will stop. This is because in manual mode the system does not know the end RPM, and as such does not know when the "run" ends and the retardation starts. So it turns off when the RPM comes back to the start RPM. It is easy to avoid though. Turn auto start/stop off or turn correction for frictional losses off (not a common option to enable when doing manual brake control). Or set the start RPM a few hundred RPM lower than the start Brake RPM. 

Let me know if there is a way to reproduce the issue of 0 hp/torque.

I have very similar problem, when I set the target RPM above 6K at the 6K (exactly 6K) the box and screen freezes, (the box still holds the brake Tq where it reaches the 6K) and need to restart the whole PC to get working again. If I reconnects the box only I got messages about invalid data.

something wrong with this update,

after  installing, the settings lost the secondary brake (set to 1 brake), and no Tq values displayed anymore..

(both loadcells works on the brake settings tab)

Good! i guess leaving it to Zero, Will not Works, does it? it's important to my dyno since we measure drivetrain losses for HPcrank calculation..

I have fahrenheit selected and its reading right but it says C

Would it be possible to add a print screen like this?

Greetings tuners,

YourDyno version 3.2.38 was released today. 

Changes:

• Added functionality to set a fixed brake % after the run is done to quickly slow down the rollers/brakes. 
• Corrected a bug which would give a slight inaccuracy in torque numbers when using two brakes and the brakes have different speed (HP was not impacted).

Cheers!

Protech, lots of info on dyno setup in the wiki. Other than that, there is a lot of explanations in the software itself. 

You can use the 'v' key in the main graph window and in the Run window with the gauges. 

Where is the instruction manual?  I can find nothing regarding setting this up . Not happy .

   How do I get to the window that allows the V key to do anything?   

Hi,

The firmware version needs to match the software version, so yes you need to do the upgrade. Just click "Upgrade to latest firmware". The system will download the correct file automatically. All units with the blue box are version 4. 

To see the coast drag, see wheel hp and wheel torque. It is negative on the retardation phase. You can select what parameters to plot with the 'v' key. Then right-click and choose "Set scale to default" to see the full curve. 

Select the AFR channel from the list when pressing 'v'. Same shortcut for gauges.

Hi,  

 I have a unit about 2 months old, There is no external marking on it to determine which version  it is.   

  First question;  A note came up asking to update  firmware.  The menu ask which version it is?   What is my answer and do I need an update? 

 Next , For the roll down drag calculation. How do I get it to plot the  retardation drag?  Yo have said to right click some thing etc. Right click what ?

 Last ;for now  I have AFR on channel one . How can I get it to plot vs RPM , for full pulls? 

 Thanks a lot. MM 

Hi! ive been playin a bit with Print page setup. set Font doesnt work properly, tried to change size and nothing happens.. should be good to make a box that everything introduced there Will appear same in the dyno sheet.
