BeamNG... we need a physical working DYNO! I know we have the digital one. But itd be much better to physically throw a car into a dyno and just let it rip in one spot and let the hp display on a screen. No more needs to be said. Its needed!
well one was going to be added, but it was cancelled, as for now, there are no plans to remake the dyno
The devs experimented with one a while ago. It never made it to a release branch and was scrapped due to some nasty bugs.
Apparently the dyno couldn't work up to the quality standars of the dev in the sense of getting the rollers to display accurate info.
