Hi, yes, the RPM setup is moved to the Run window. 

Walter, for your hub dyno, choose:
RPM1 input function: Load cell1 RPM
RPM2 input function: Load cell2 RPM

Then in the gear ratio setting, choose either OBD2, Tacho or "Set gear ratio manually".

To see the lock brakes setting, choose the RPM setup above (using two RPM sensors). Then it appears as an option in the Brake control setup in options. I will change the behaviour so it is make it is visible all the time, I think that's easier. This setting makes both brakes work in tandem all the time. Essentially it will only use RPM sensor 1 as the input for controlling RPM, then control both brakes using the PID controller for RPM1. 

wow! nice good updates! I have some questions about this latest update, since im using a hub dyno with 2 brakes/2 load cells /2 rpm sensors.

I noticed, i only can choice load cell number, not rpm sensors. 

Since i use already 2 Eddy brakes, how do i have to configure it right now? about MOI,etc.

i see different RPM Setup window, i asume i'd have to put load cell 1+2 in both inputs?

I see about "lock brakes", but i can't see that option in the software, can  you explain please how does it will works exactly? 

About 5 point: turn off gauges doesnt Works to me. 

bmgjet He means in Run Windows i think..

There no rpm setup window in options under basic dyno setting for me

Greetings tuners!

A new big software change was released now, 3.01.80. It requires download of new firmware, version 1.17. Just press "Upgrade to latest firmware" in Options-Firmware Upgrade. 

Changes:

1. Support for OBD2 RPM readings over Serial, USB or Bluetooth. This enables automatic gear ratio calculation. 
2. Support to use the 2nd RPM input for direct engine RPM measurement. This also enables automatic gear ratio calculation. You will need another RPM sensor or a spark plug adapter like this one: Spark plug adapter. Or use an output from the ECU (0-5V square wave). 
3. Support for CVT and similar gear boxes with variable gear ratio. This feature is not fully tested yet, so use with caution (let me know!). 
4. Added support to test 2WD cars on 4WD dynos. This is done by adding separate Moment of Inertia for front and back rollers + more options on the RPM setup. 
5. Ability to turn on and off gauges in the Run window (hotkey = "V", same as for curves in main window).
6. Added "Bring to Front" and "Send to Back" for gauges.
7. Added Roller/Hub RPM gauges.
8. Added ability to lock brakes. This for setups with 2 brakes, where independent control of both brakes is not wanted.
9. A couple of cleanups here and there.

Note: This is a big update to many parts of the system. You will need to go through Options->Basic Dyno Settings and in the Run Window check out "RPM setup". You will need to update some of your settings. You also need to download the latest firmware. 

Happy tuning!

Greetings tuners,

Software version 3.01.78 was released today. 

Changes: 

• Support for sessions. A session is a collection of runs, typically the same car/engine, and it stores the gear ratio, brake setup, auto start settings, etc. The name of the runs will default to the session name plus a number. The raw log files will also be stored in the same folder. A session can be opened at a later time when you want to test the car/engine again and the same setup as last time will be applied. 
• Ability to set the two Y-axes to the same scale. Right-click and select "Synchronize Y1 and Y2 axes". 
• Fixed a bug when the brake and logging did not turn off at the correct moment for RPM sweep when Frictional losses correction option was turned off.

Enjoy!

Greetings tuners!

Software version 3.01.77 was released today. It brings the following: 

1. Ability to trim the graphs and straighten the graph where needed. See it demonstrated here
2. Moved the IIR filter operation after the run (offline) such that the automatic start/stop now has minimal delay
3. Auto stop run will now wait for the duration of the RPM brake curve as a minimum, i.e. it both needs to have reached the end RPM and the duration of the curve in time before the brake is turned off. This enables any curve and it enables holding the RPM at max for a while, etc.
4. Brake sweep improvement. You now set the RPM per second you want to achieve. Brake can still only either increase or decrease in this mode, but the rate is now depending on the actual speed of the RPM change. 
5. Improved print functionality. The height of the graph windows will be used to set the size of the graphs when it is printed. I.e. you can have a large HP/Torque graph and a small lambda graph below for example.
6. Added an "Are you sure" when exiting YourDyno
7. Fixed a couple of bugs

Hope you like it!

Greetings tuners!

Software version 3.01.72 was released today. 

Here are the changes:

• Better resolution for the brake control analog min/max voltage specification
• Support for brake sweeps in both directions, i.e. simulated steepening hill and simulated flattening hill
• Fixed some bugs around automatic run start/stop and corrected handling of specified start delays (for RPM/Brake sweeps)

Enjoy!

Indeed, guys, there was a mistake in the Gear ratio when using 1 RPM sensor. 

New version 3.01.68 is released. 

It’s not the firmware. As I mentioned before, I run the program on my laptop after upgrading the firmware but with previous version of yourdyno without any problem. Everything you told me I double checked. When you set the rpm on the box to calibrate, the option to record the calibration always stays grey. And the rpm never rises. Pulses and everything is ok. Copied everything from working (previous) version.

OK, I will remove the firmware version 1.16 until it is cleared up what this is. 

So it happens when you upgraded the firmware? Did you double check the Pulses per dyno rev? Also make sure gear ratio is not 0, then calibrate will not work. Enter any number except 0 for the gear ratio.

xtcund please let me know after double checking the above points, and also let me know if the other sensors work. Send me a raw data log file from a test run.

Yes. Seem to be having the same issue. Cannot get an rpm from gear ratio. Works with previous version though.

Hi again Jostein, after updating the software and firmware, i have no RPM. i had to uninstall everything and install previous version again... checked everything after having dyno working again and compared the two configs and everything is configured the same way...

I cant calibrade Gear Ration and i cant dyno any car because RPM is always dead...

Hi Jostei, everytime i update i have to go through the print layout configuration again. is there any simpler way?

Hi Jostein, thanks for info! yes, RPM sweep Works good , just for testing on my dyno only. What i'd like is the Sync option , not sure if the same sync option can be added too to RPM sweep.
