the error pops up when you select rpm curve. i put it out and the error was gone. I did a gear ratio setup with the tacho and now the error stays away

Ah, ok thanks. I will make a check in the software so that the error message is clear in that case. 

the real probem whas that i didn't set the gear ratio. got the problem again after installing the software. i dont have a rpm signal yet. i am waiting of my optocoupler. i did a setup with the tacho and it works now

OK, good to hear it works!

problem solved!!!! i put the usb in a different port on the pc than where it was the first time while installing yourdyno. I deleted the usb/com port driver manually and the yourdyno software. disconeccted yourdyno and installed yourdyno again an put the usb back and it worked again. something went wrong with te usb i quess. i use windows 10

Hi,

Can you save the options (Options->Backup options to file) and send it to me at jostein@yourdyno.com? I will check. 

In the meantime if you're in a hurry, you can exit YourDyno and delete this directory: (navigate with a file explorer): 

%localappdata%\Fonneland_Engineering

Then restart YourDyno. It will have fresh options. 

Please send me the saved options file first, so I can fix this for the next release.

Inside the cabinet with the PC, YourDyno and Sportdevices power supply

printscreen of the firmware and data connection check

I installed the sportdevices powersupply today and i wanted to make a test and i get a error message.  maybe i changed some setting that i didn't noticed.

I attached a printscreen of te pop up it only happens when you want to make a new run. I can adjust the brake by hand and it sees the correction sensor and give me the data tranfer number. 

That's a nice photo, man! 

First of all.. Thank you Jostein for your fast shipping! I am working on the Dyno as much as possible to get it running but it is busy at my shop so I need more time for it😬😬 While I was wiring up the system I was thinking about using a temperature sensor on the telma CC160 eddy brake to monitor the temperature with the extra channels of the VM167  and make a warning light on one of the outputs or a warning message in the software (new plugin😛) that the brake is getting hot. But does someone know the best place to put a temperature sensor on the Telma brake for a good measuring? 

Picture of my system at the moment with a Audi TT on it. 

Hi,

Most use analog output to control the brake power supply. I believe PWM or analog works equally good though. Remember to swap the jumper inside the YourDyno box if you go for Analog. 

Yes, some good news on the external environmental sensors. I am making a plugin to support this sensor:

The plugin is super simple, just waiting for the sensor to arrive. Indeed if the YourDyno box is within a cabinet or something it is better to have an external environmental sensor. Stay tuned!

Thank you for your reply! Last week I did some testing with the old original system. It was fun but it is much nicer to have a dynograph of te measuring. After reading a week on the internet I doubt about the Sportdevices SP5 (€3200 including PWS v3.2) or the YourDyno kit with PWS v3.2 (€1700) After some playing with both free software is decided to go for the YourDyno! A big reason for me was the simplisety of using the software and this forum for the questions and the fast replys from Jostein. So I ordered the parts to make te MAHA work with YourDyno. Also ordered the YourDyno kit. (thanks Jostein for the super fast response and order updates!) I hope the kit arrives tomorrow 😁 Also I bought a Sportdevices Power supply PWS V3.2b, the Velleman VM167 And a 12volt 20Amp power supply for the Ebay relay board to operate te cooling fan and valve of the pneumatic lift with the YourDyno software. And the 5Volt 10Amp for the extra sensors via the Velleman VM167. And for the good view a 42 inch touchscreen monitor for the PC. 

I was wondering what the best way is to control the PWS 3.2b. I have a Telma CC160 Eddy brake that works on 192Volt and I measured a resistance of 11.9 Ohm. So that will be 16 Ampere on max load. The shop that sold the PWS to me adjusted it to max 16 Amp. What is better for controlling the PWS with digital PWM signal or analog 0-5Volt? What would be the benefit of each signal? 

Is there an option to make environmental sensors (temperature, humidity and air pressure) external so I can put al the parts with the YourDyno module  inside one control cabinet so the heat of the powersupply and PC give a wrong number?  Maybe possible with using the VM167? 

Your Maha is looking good!

For your questions:

1. No problem with a bar type sensor. The distance to the sensor is not important, what is important is the distance to the (center of gravity of the) load when you calibrate. But that load cell looks a bit old and taped up, a new one is really not much money, so I would maybe go for that. Even if it works it may not be very linear
2. Yes, you can add your company's logo to the printout. Just go to Print page setup
3. On the CPU load. If you have very many curves in the same graph then the cursor is lagging a bit with a slow PC. You can move the mouse around and it will find the closest curve and the closest point on that curve and show this. Other than that, if you load up with many sensors (through plugins) then it is quite a lot of calculations every second, so you may need a faster PC. For example you can log and display 8 thermocouples, 5+3 analog sensors plus a whole lot of OBD2 data in addition to controlling 2 brakes and calculating HP/Torque... The PC for our rolling road similar to yours is really low cost though, and it is fine. 
4. One csv file with a few runs is typically a couple of MB only

Looking forward to seeing your system in action!

fresh paint and nice even with the floor.
