Here is a general guide for upgrades:
Upgrading your old dyno to PEREK dynamometer system

Please share more information about this dyno and I'll help you with component selection. I'm especially interested in speed sensor count and type, load cell type, eddy brake count and model.

BD3 Tool is a part of Dyno2 software that runs on my dyno controllers. I don't have a standalone version of it.

I guess you want to limit the maximum current in the BD3? In your case the easiest way would be just not to send PWM or CAN message which request current that is too high for your brake.

Hello Ronald,

we have a BD3 and would like to integrate it in our Dyno.

Reading BD3 Manual, for the CAN configuration it is required the BD3 Tool which I suppose can be executed on a windows 11 PC.

Where is located the download link?

Thanks

Andrea

Yes. BD3 supports this kind of eddy brake.
