Channel 111 - ElpsTm
C211
Channel 111 uses Timer 2, channel 211, to measure elapsed time in
seconds during a test profile. It allows decimal precision adjustments, if
desired.
Channel 112 - SAEPwr
C100*C101
ECEPwr
Channel 112 is used to calculate the “corrected” rear wheel power for the
test vehicle. Channel 100, the rear wheel power, is multiplied times
Channel 101, the SAE
[ECE]
Temperature and Pressure Correction
Factor. The SAECor
[kECE]
correction Factor, Channel 101, is for
estimating what the power would have been at 77
0
F
[25

air
temperature and 29.23 in.Hg
[99kPa]
barometric pressure in dry air.
Channel 113 - STPPwr
C100*C102
DINPwr
Channel 113 is used to calculate the “corrected” rear wheel power for the
test vehicle. Channel 100, the rear wheel power, is multiplied times
Channel 102, the STP
[DIN]
Temperature and Pressure Correction
Factor. The STPCor
[k DIN]
correction Factor, Channel 102, is for
estimating what the power would have been at 60

F
[20

air
temperature and 29.92 in.Hg
[101.3kPa]
barometric pressure in dry air.
Channel 114 - DJWhPw
C112*C82
Channel 114 is used to calculate a “comparison” rear wheel power for the
test vehicle. Channel 112, the SAE
[ECE]
corrected rear wheel power, is
multiplied times Channel 82, DJCorF, the dyno comparison factor.
Channel 114, is for estimating what the power would have been on a
competitor's dyno at 77
0
F
[25
0
C]
air temperature and 29.23 in.Hg
[99kPa]
barometric pressure in dry air. This channel is an estimate only, used for
comparisons with another dyno, and should not be used for marketing or
development purposes.
Channel 115 - SAETrq
lb-ft = C112*5252.113/C125
nm = C112*9549/C125
Channel 115 derives a corrected torque value in lb-ft
[nm]
from the SAE
[ECE]
corrected power calculated at the rear wheel in channel 112, using
Engine Speed from channel 125. Although this is not the actual torque
applied to the ground, it is a common value used in marketing and
advertising to represent corrected torque of the vehicle under test.
Channel 116 - STPTrq
lb-ft = C113*5252.113/C125
nm = C113*9549/C125
Channel 116 derives a corrected torque value in lb-ft
[nm]
from the STP
[DIN]
corrected power calculated at the rear wheel in channel 113, using
Engine Speed from channel 125. Although this is not the actual torque
applied to the ground, it is a common value used in marketing and
advertising to represent corrected torque of the vehicle under test.
