hi

first question on the forum 🙂

i was wondering if i can use the 2 rpm inputs on  the front and rear roller on a 2wd dyno?

how does the software deal with that?

the reason is that i would like to see if the tire deformation does give different speed on the rollers.

How are you strapping the car down.
On my which is 2 rollers when you have a perfect strap down the rear roller doesnt contact the tyre under full load since the car rolls up onto the front roller which has the brake on it.

Hi yes thats what i think is the problem
Because when you accelerate on the front roller only
And calculate the loss on retardaion
You are on 2 rollers.

Hi,

With a very minor change a slip measurement plugin can be made. I will do it.
