Smoothing of 3 works quite well. Using the Focus ST profile with a weight of 3459 and the correct wheel size works quite well.

 

I've been using these numbers to create a custom car, just wasn't sure what smoothing effect to use

 

How do you guys get Virtual Dyno to even run? I've tried on a couple different computers but can't get it to create a profile or open a log, just get an unhandled exception. One PC W10, the other an old Vista box, same exception.

Sequence:
Open VirtualDyno
Created custom car with our RS info
Load datalog from AP (recording only TPS, RPM, Boost, Time)
Select FocusRS from custom list (which is empty until I create one)
Receive Unhandled Exception
