Folks,

YourDyno software version 3.3.75 was released today. A minor release. Changes:

• Avoided recalculating averages every time the Options menu was closed (resulting in some delay)
• Calculation of average values was a bit slow with many long runs, so an option is added to only calculate average on Engine Torque and Engine Power. This makes calculating averages faster when reading a file or completing a run
• Reduced the time over which the acceleration is calculated, resulting in quicker response
• A few other minor cleanups

Enjoy!

Hi folks,

A new minor release 3.3.74 (beta) with a few cleanups/changes: 

• Support for 2 water brake valves that move in parallel. This is used for setups with 2 water brakes in tandem, each with its own valve
• Fix of bug in Water brake valve auto zero when using Auto save and auto restart. Earlier auto zero only worked with manual run (re)start
• CAN bus analyzer data update fix

Enjoy!

@admin

Fantastic upgrade!  What would be nice is if the brake control box in the run screen changed when in load control mode so the up/down buttons became start and finish rpm buttons. This would save constantly going into the setup box, then to the load control box and altering them from there. During a fresh engine run in/ tune I can alter the sweep range dozens of times, back and forth from screen to screen. Best dyno software out there!

Hey tuners!

New YourDyno software version today: 3.3.71 (beta)

Changes:

• The RPM test range (start RPM to end RPM) is now indicated in the Engine RPM gauge in blue. Quite practical when you switch between modes and adjust start and end RPM to always see it in the gauge. This is only implemented for the analog RPM gauge
• Power and Torque gauges now include power correction in the value displayed
• The average value of all channels are shown in results table bottom row (when master channel is Engine RPM). The average is calculated over the RPM range set in Options->Average calculation
• Results tables now also show the best value in green. This is done for each channel that has a "Higher is better" or "Lower is better" setting in Options->Visual styles
• Manual brake control mode (direct control of the brake %) is changed such that you can now control the brake before the run starts. Useful when warming up the engine for example
• The Auto zero of water brake valves was improved. There is now a small window popping up showing the status of the zero positioning when running, and there is a Cancel button
• CAN bus analyzer improvement. The analyzer can now handle many more CAN bus channels at once
• Printing of new result tabs did not work before, this is fixed

As always, any issue let me know Enjoy!

Thank you so much who answer my question especially jostein..already solve my problem..

Hey folks,

YourDyno software version 3.3.67 (beta) was released today. A number of minor improvements here and there!

Changes:

• Saving of manual axis setup in graphs enabled
• Automatic clipping graphs at the start of the run to coincide with the defined start RPM. This way, if the RPM does a little "loop" at the beginning of the run then this part of the graph is removed. This gives cleaner graphs in those cases
• Support for delayed recording start. For example you can define the sweep to be from 2000 RPM to 7000 RPM, but start recording at 2500 RPM
• More features on the Ramp up brake before run. Ramp up brake before run is used to ensure the engine is nicely loaded by the time you reach the start RPM. You can add a derivative factor, which means it will brake more if the acceleration is fast. You can also now define a ramp up brake curve vs RPM rather than the default linear ramp up
• A number of improvements to the DTS brake mode (used for DTS dynos and other dynos with two water valves). In addition to the improvements, the whole DTS menu is now hidden for other users, as it is irrelevant
• A Jump to Bootloader button was added. This is useful if there are any issues with updating the firmware (like automatic driver install not being fast enough)
• Better time synchronization on Math channels
• Columns in data tables are more compressed when printing, resulting in more data on each printed page
• Company Logo error was fixed (used to say "Your Company" until you opened Options)

Enjoy! As always, any issues let me know.

Cheers,

@drmototuning send me your config file to jostein@yourdyno.com. I will take a look at your options.

I suspect you have a power sweep configured (for example) for 3000-7000rpm, in which case the start button will not be available if you are above the lower limit (3000rpm).

Hi jostein..after upgrade firmware i cannot continue make new run when wheel still running..i have to stop the wheel to make restart button appear..any tips or can i go back to previous version? Thanks..  

@mjpower Hi,can you try to go back to 3.2.138 (this is what I used for long time without an issue) and check the results? I see about 10% difference in braked vs inertia mode.

@admin Hello Jostein,i just sent the files. I hope you can find what causes the difference.

I have been experiencing the same thing i think… i have had a 2jz in the engine dyno struggling to find some missing power, maybe i should downgrade also and try again 🙂

@radics1 there must be something different in the options. Send me the backup'ed options file from 3.3.61 and 3.2.138 and a raw file and I can take a look.

Hello Jostein,

Today i was able to do some runs. In inertia only i get 144hp,when measured in braked mode,the numbers are low,somewhere between 120 135 hp. If i unselect the brake during retardation box,the retardation is completely missed even in rpm sweep mode. I reverted back to old computer with 3.2.138 sw and did the same runs. 145hp inertia and 148 braked. So there is a significant difference between sw versions in braked mode. Do you have an idea why this happened?

Thank you in advance!

@osi great to hear. I have seen that a few times before. Windows, in its wisdom, sometimes assigns the same COM port number to two different devices. Good you found it out.
