Scan Gauge 2 How it works
Can someone explain to me how the SG2 works. I'm electronically inclined so a technical explanation is ok also a watered down version wouldn't be bad either. I know the SG2 gets it's info from the OBD2 computer which get's it's info from the various sensors. But how does it calculate MPG and gallons to empty, etc... Thanks for the help

I thought that EVERY car went away from a stoichiometric ratio (to a leaner ratio) at certain low load conditions. Is that not true?

The ECU will always try for 14.7:1 even though the engine may want/need something different.
|
diesels can lean out a lot more.

I thought it read the injector pulse width from the ECU and calculated fuel usage from that.

Hello -
One thing I have noticed with other OBDII readers (like the CarChip) is that they also only monitor 4 values at once. This leads me to believe that the OBDII "bus" can only place 4 "instant readout" values on the bus at one time. No proof, just observation. CarloSW2 |
