Scanguage does not read injector pulse width to figure. It extrapolates mileage by reading iat, map, tps, and other sensors. That's why you have to calibrate when you first install it when you fill up. The only one that I know (that is reasonable) that does is MpGuino which I use. Great units. Every time you change anything (sensor modifying) when using a ScanGuage you have to recalibrate it.
