Hi Jostein. The calculation you describe is what I would expect. When i talk about speed, I am saying that the losses are related to the roller speed...

Have a look at some Maha dyno graphs, they are have a nice model.

Yes with Hub dyno you will not see that much difference. On car that starts off at 230bhp and then goes to 450 bhp - it's quite a lot of difference.

It does increase with power, more thrust loading on helical gears etc. But, the biggest increase in loss is through tire flex. Especially when you ...

No 🙂 Try it yourself - run a car standard, then run a car once it is tuned with more power. You will see the drive train loss is identical - the perc...

You misunderstand me, Currently the calculation is ONLY related to roller speed and not the power output. As power output increases, so does the loss...

New software is all good at my end, printed out may plots already.

it will be harder to turn but will turn faster for a given movement - hence more power 🙂

Kess is a a tool to read and write ECU flash, it's nothing to do with actual tuning.

That will be very useful. Can it also be made so that we can choose what is summarised at the bottom? E.g. correction factor, env data, min or max of...

The MOI must be wrong. You will get different wheel readings due to friction/speed in different gears. You need to set the MOI so that you get the sa...

Thanks Jostein 🙂 Might have another for you -the custom colours aren't saving for me - no deal breaker!

Power sweep bug verified fixed here 🙂 I am still not saving my engine power and torque to csv. Also another bug that doesn't happen all the time. If...
