Are you being intentionally obtuse? You keep misrepresenting what the use of this is for. Of course you can’t measure acceleration. That is the change in velocity with respect to time. Nowhere in this system are we measuring time. Again, this is a relatively low cost unit designed to put a load on a motor to test.
If you want a Dyno there is one available for about $1000, and you will still need an esc and a computer to run the software. Oh wait, you have issues with that too…
Now if you have something constructive to say, then I welcome your input. But if you are just going to be a naysayer, then don’t bother.
