Individual Dyno Results:
The legend below has the following meaning:
- Dyno Run: Dyno run file
- Timestamp
- Temp(F) = Temperature (Farenheit)
- RelH = Relative Humidity
- Pressure(Hg) = Barometric Pressure
- DA(ft) = Density Altitude
- WHP(unc) = Uncorrected wheel horsepower
- WTQ(unc) = Uncorrected wheel torque
- WHP(SAEd) = SAE Corrected Horsepower using Dynojet weather station.
- WTQ(SAEd) = SAE Corrected Torque using Dynojet weather station.
