TOPIC: scan gauge

how acurate are they for C02 readings

Didn't know they could read CO2, do you mean O2 sensor values?

SCANGAUGE PROVIDES REAL-TIME INFO ABOUT THE AMOUNT OF CO2 IN YOUR VEHICLE PRODUCES ALLOWING YOU TO ADJUST YOUR DRIVING STYLE AND REDUCE YOUR CARBON FOOTPRINT THIS FROM SCANGAUGE INFO SHEET

Hi Milton

I have a ScanGauge as well as an OBDII scanner, I'm fairly sure that the CO2 reading is a representation via calculation of the O2 sensors and other factors, there are no physical CO2 sensors in any vehicles that I know of.

The scangauge is good for watching your mileage at run-time but I would still recommend getting and OBDII scanner.

thanks my 98 tahoe shows 7 1/2 miles for 1 lb c02 whats normal readings ron grooved my throttle body also i have bruce mcberneys compensator , mapster set at 4 volts still trying small reductions hard to not do to many changes at once i went from 12 mpg to 20 mpg not bad for a 4 wheel drive it is better than a new one

Milton, you MUST restore teh vacuum leak caused by the PCV Vacuum line! The Condensator, while helpful on the average car, is disadvantageous to the actions caused by The Groove.

I'm just saying I wrote the manual over a three year period and know this stuff pretty well is all...
