Hi, Yes, the Digital I/Os are for future expansion. First plan is to support frequency based sensors, typically fuel flow sensors, plus the option t...

Correct, the MOI will affect the load that the load cell sees during a sweep. But your load cell should non-the-less tolerate the full torque of the b...

Sounds good @six_shooter! Any help on adding plugin support for new sensors would be great. A Megasquirt can bus config file would be nice also!

Do a test by shorting the thermocouple input with a regular wire. It should show room temperature. The range for the K-type thermocouple is huge (-200...

Hi there! The easiest way to calculate the correct load cell size is use the max torque rating of the brake. You don't need a larger load cell, no m...

From your description you connected it correctly and configured it correctly. There is nothing more you need to do. Since the RPM2 input is working ...

Hi, The Engine RPM channel is always equal to Roller RPM * gear ratio. This is what is used to calculate the power and torque, and to control the b...

Hi, You can try a usb isolator, like this one: www.usconverters.com/usb-isolator It must have its own power supply.

Yes, that is an easy addon to the existing plugin for anyone with coding skills who wants to give it a go. I can do it too, just a few things on the t...

The Pulses per revolution is here: Run->RPM Setup click the RPM setup tab.

@erik-malmstrom, you are right, thanks. I will fix in the next version.

Hi, Each roller has a MOI of 2.25 kg*m^2, so 9 kg*m^2 in total. There is no fixed max number, but the runs get faster and faster to a point where...

Hi, If your PC is fast enough (most modern PCs are) then use 20Hz. You should probably reduce Kp, increase Ki and reduce Kd a bit. Try something l...

@bendd Sure, I will add this! Thanks again for the cool video.
