MAHA LPS 13 project. Many questions  

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.

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

OK, good to hear it works!

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

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

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

• Hi. I have many questions about this dyno. Can you help me? Send me Please your e-mail .

Hi, you can try to ask the questions here.

Maybe you can ask me the question here so other people can read about it. What do you want to know? 

Hey.

What is the maximum power that this dyno can measure?
Are you satisfied with this software or do you have any comments about it?

Have you some photos how to connect a strain gauge to a telma brake.

google translate is my best friend😀

Hi Domino,

If you read this topic most of your questions are answered. I still use the original strain gauge of the MAHA. A technical guy from Maha UK told me they stil use the same one on the latest models. I attached it to the yourdyno and calibrated it with some weight and ik works fine. The signal is very linear. I measured the internal resistance of the Telma CC160 brake (11,8 ohm) and connect it to 200 volt. And set the maximum current of the power supply to 16 Ampere. I use the power supply from sportdevices. Simple installing and reliable in use. For the speed sensor trigger wheel i used a 36 tooth the camshaft chainwheel from a Volkswagen 1.4 TSI distribution. Did some machining to make it fit on the axle of the original triggerwheel. And made the yourdyno hall sensor on the original place of the old inductive speedsensor. And it works fine! I got a wire diagram of the LPS 13. I will post a picture of the connections but have to find it on my workshop. 

Here you have the wiring diagram of the load cell (strain gauge).
