Review: OBDSCAN

Drive test 2: Reported throttle position at wide open throttle -- does throttle position at WOT reach 100%?

Result: Yes (confirmed)

Speed	Intake Air  temp	Air Flow	Throttle
19MPH	100.Deg	331.3gm/sec	14.%
21MPH	100.Deg	508gm/sec	100%
23MPH	100.Deg	1437.1gm/sec	100%
30MPH	102.Deg	2034.3gm/sec	100%
37MPH	102.Deg	1433.1gm/sec	15.%

To get the volume of air:

Volume(cu.ft./min) = n(lbs/min) x 10.73 x T(deg R)
                       (29 x P(psia))

Absolute temperature = deg F + 460 = deg R
