I have not received my new TCH just yet. I have used the ScanGauge II on 3 cars I have owned. So far I have simply placed it between the tack and speedometer. It does sometimes block the idle portion of the tack which don't really matter. I hope this week my new TCH should arrive. I will try to mount the gauge in the 'easy to read' area.

I really like this SG. I found the SG can show 4 readings at one time. Water temp, gallons per hour, throttle position, engine load. It can also read out the voltage of the 12 volt battery. Once calibrated it will give you your correct speed. The gauge also has a tack display to show your rpm. To change any display, you simply press any of the four display buttons till you get to the readout you want.

I like watching the 'engine load'. Seeing, 50 is a level highway. Anything under 50 is downgrade, coast or glide. At 50 or above is upgrade. I have places in town and coast 1/3 mile to a red light. On the highway out to our house where I can coast a 1/4 mile to our turnoff.

All three of the last gas engine cars I have owned get 1 to 4 mpg 'combined' mpg higher than above the factory sticker displayed highway gas mileage. The 2006 Ford 500, V6. I consistantly get 31 comb, 35 highway. The sticker shows 21/29. Thank you scan gauge for teaching me to drive for better gas mileage. I'm sure looking forward to seeing what I can do with the new hybrid. Thats once it's broke-in at approximately 5000 miles or more.
