Engine correction factor

[gamarilla]

Does anybody have the Engine Correction Factor formulas, based on Atmospheric Pressure, Humidity and Ambient Temperature? DIN, SAE, or any standard will be welcome.

Hi,
SAE has suggested the following formula for small engines

Corrected bhp = Test bhp*{101/(B-E)}*sqrt{(273+t)/288.6}

Where,
B = average observed barometer pressure in kPa
t = induction air temperature in deg C
E = average water vapour pressure in kPa
