BIG THANKS TO PG FOR PUTTING ALL THE DATA TOGETHER !
NOTE: ALL THE PARTS THAT CAME WITH THE ESS KIT IS WHAT I AM RUNING BESIDE THE BELT SYSTEM AND INJECTORS !

Dyno Database:Individual Dyno Results:
- SAE Corrected: 666whp @ 8000 RPM, 439wtq @ 7700 RPM
- STD Corrected: 683whp, 450wtq
- Uncorrected: 678whp, 446wtq
The legend below has the following meaning:
- Dyno Run: Dyno run file
- 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.
HP, TQ, with IAT:
NOTE: AFR (Mearsured) = Dyno AFR sensors. AFR (Actual-B1), AFR (Actual-B2) are the BMW O2 sensors. There seems to be a difference between the two; a difference that is not normally seen during dyno tests. One or the other is out of calibration, and by the looks of it, the dyno AFR sniffer looks like it's out of calibration, as we can see in RunFile_023 the dyno AFR is completely wrong, but in RunFile_022 the dyno AFR matches BMW O2 sensors perfectly. Moral to the story: BMW O2 sensors are correct, but dyno RunFile_023 isn't.
