There is a bug when trying to center when printing, Im trying center but it reset and on the paper is off.
Hi, I double checked this, and everything looks correct. Can you send a screen shot?
still having issues on the results page , hp tq graph , seems the max torque uses the scale on the left of the page , when you hold cursor over torque line on graph it displays correct using the scale on right . but on the bottom of page max torque is not displayed correct seems to use scale on left
Greetings tuners,
Version 3.01.58 is released :-). It gives the following improvements:
- Much improved print functionality. You can now include a header with text and image, plus print quality is better.
- All environmental conditions are shown in the table below the graphs, both on the screen and on the print
- Gear ratio button added in the Run window, after popular demand 😉
- A new "Clear all runs" command available in the main menu
- Fixed a bug that when you change the brake curve, you had to close and open the Run window for the new curve to be recognized. Now it is updated immediately.
- Fixed a bug so that "Spacebar" to start/stop a run actually works
Enjoy!

that's wonderfull. really am missing that funcionality. always showing pics instead of real prints and that's not what people want.
Also, if i may ask, the things i woulg like to have printed was:
PAtm
temp
humidity
as well as the norma used
Hi,
The new print functionality is making good progress! Coming soon.

Hi Jostein,
The loss calculation is a big addon to the software but i have two big questions i hope you can answer. I think i´ve seen somewhere how to really read the losses instead of calculating the %. I am still measuring with the option "enable aditional horse power correction". do you know where you have this explained and what to do to calibrate it?
Second question is the print format. I know that the print format is actually a print screen but i think you could take the software into a new level by adding a very good looking print forma.
A friend of mine was developing a litle excell worksheet that could convert the CSV's into a beautifull print format but he is at 50% and has litle time to finish. i have attached the layout that he developed reading the csv's. Do you have any easy way or any intention of making something like this in a near future?
Thank you very much,
Luís Matos
PS- we are still waiting for our Bosch FLA to arrive from service to implement you software on it. meanwhile we are still using the inertia dyno.
Hi! do you have any update for that conversor? should be good use with yourdyno!
Greetings,
Software version 3.01.56 was released today. It brings only 1 change: An improvement to the gear ratio calculation when using 2 brakes. Previously the calculation assumed the two wheels where spinning at the same speed, which is not necessarily correct. Now, both wheels speeds are properly included in the gear ratio calculation.

Greetings, tuners!
A bug fix for those of you running Imperial units. When saving and opening files, there was a bug in Engine Torque, which was read as metric. Wheel torque was correct.

Hi Luis,
You can measure the losses by clicking the option "Enable correction from Frictional losses from retardation data". The way it work is this:
You do a normal run from low to high RPM, then when at the RPM limit you press the clutch and let the system decelerate by itself all the way down to the starting RPM. Since we know the MOI of the system, we can measure the resistance in the drive train from the time it takes to decelerate. From this loss together with the wheel HP/Torque that we have measured, we calculate the engine power/torque.
Note this method is still too conservative when seeking to find the true engine HP/torque. This is because the drive train will have higher resistance at high loads than at low load (that's why the gear box may need cooling for high horsepower engines, it certainly does not need cooling when we are coasting back to low RPMs...). So it is better than just guessing, but you may still add some % in the "Additional horsepower correction" to compensate for the loss at high load.
Yes, I agree with you that the printing shall be better. I am working on improving this now, should come in the next release!!
Cheers,
Jostein

Greetings tuners!
YourDyno v3.01.53 was released today. Here are the main changes:
- Support for stepper motors to control brakes! See it demonstrated here: https://www.youtube.com/watch?v=-Tbp4D09nOs
- Ability to edit the brake curve by editing the time and RPM numbers. This is more accurate than dragging points on the brake curve up and down, left and right.
- Better resolution on PWM brake min % and max % setting. For RC Servos setting PWM min to 4% and max to 11% gives the full range for the servo like before. However, depending on the application, the endpoints may need to be adjusted to less than the max travel of the servop, and to do this you can now vary the min and max values with better precision.
- Improved timing of the data transmission. It should now be very close to 100 samples per second, while before it varied from unit to unit between about 95 and 109 samples per second.
- Fixed a bug where the Aux3 channel would show incorrectly in the graph when IIR filter was active.
You need to download the new firmware to use stepper motors.
Enjoy!
Greetings tuners,
A small software update is released, 3.01.52. It includes two fixes that a few of you have reported:
- An error saying "Cross thread operations not valid" is now removed (it happened on some computers when coasting back to the start RPM)
- An error when a print dialog box was included in the actual print. Now it is removed.
As you may see in Options, support for Stepper motors for brakes is underway! It is not released, but coming very soon. It needs new firmware, so don't try to test it yet.
Enjoy!
If anybody else gets this problem, the solution was to delete the saved settings. You do this:
Depending on your Windows version, go to either:
%userprofile%\appdata\local\Fonneland_Engineering
or
%userprofile%\Local Settings\Application Data\Fonneland_Engineering
And delete everything under this directory.
YourDyno will start fresh with no settings from before.
Cheers,
Jostein
