Dyno correction factor
WebMay 9, 2007 · The equation for the dyno correction factor given in SAE J1349 JUN90, converted to pressure in mb, is: where: cf = the dyno correction factor. Pd = the pressure of the dry air, mb. Tc = ambient temperature, deg C. But this formula can't be correct as Cf should be 1 at 990mbar and 25 deg C! WebUse Station Pressure reading and not the 'corrected' barometer reading. Station Pressure : (in/Hg) Temperature (F): (in Degrees) Relative Humidity (%): Input DATA Please. Link to:
