Hello.

With the strong support of Ernst S, a new version of the DZR has been created once again.

The unreliable input regarding estimated inclines and declines has been replaced by a relatively simple rolling test, which now allows the actual motor power level (expressed as an average percentage deviation from the target value in the range of 2000 to 4000 rpm) to be determined with somewhat greater certainty.
Of course, it remains essential to determine the actual speed at 2000 rpm and the actual vehicle weight as accurately as possible, because these parameters significantly influence the result.
If this is being neglected, the DynoJet dynamometer still only serves as a comparison tool, for example, before and after tuning modifications.

Search: "Drafting calculator" in "Technical articles" yields the following result:

THX

I've always searched for "draft test" and haven't found anything.
