Amount of decimal places of the Parameters rpm and time?

Post by MingLotus »

Hello,

maybe it is obvious for KManager/KPro-Users, which I can use at the first of April 2014, so for me is the topic given above a matter of cancellation, when doing a street tune.

The examination of the machine precision shows that the rpm [1/min] should have on decimal places (from a real value) and the time [s] should have three of it to log with 5 Hz, which is a minimum requirement to get smooth difference quotient produced power curve in the one hand and in the other hand to prevent rounding errors. Sadly I didn't find the setting in the KManager to check or to set this necessity.

If it is not possible, e.g. rpm is a number like 1000 1/min (without decimal places) and time is not existing because of the well known datalogging frequency or because of to less decimal places I will have to do a cubic spline interpolation...a lot of work to do...therefore my question given above.

Could anyone bring some light to this decimal places question?

P.S. I will use the export function of the kmanager or if possible a DDE Server of the this program

Many thanks in advance for your effort :-)

Anyone here who can send me a log file? I am interesstet in rpm and time.

Many thanks in advance for your help :-).
