Review on ScanGauge SG2 II Ultra Compact 3-in-1 Automotive Computer - Real-Time Fuel Economy Digital Gauges, Black, 5 Inch by David Butterfield

This little thing can make your old car compete with its MUCH newer counterparts with real-time monitoring of key parameters such as battery voltage, fuel consumption, tire pressure on some cars, coolant temperature, transmission temperature, fuel consumption in gallons per hour, instantaneous fuel consumption, consumed Performance, programmed when filling up to see how many miles to empty, etc. etc. I used to have a Prius and since I got rid of it I miss the instantaneous and average fuel consumption. Economy that he would display on his touchscreen. I'm barely scratching the surface of what this thing can do, but my 2003 F-150 feels a lot more modern with coolant temp, instantaneous fuel economy, average fuel economy and battery life. Voltage is displayed for me to check. I use a lot of warning strobe lights as a technician. So if my battery is getting low, I want to know BEFORE it's completely thrown to the wind. They can all be LEDs but with what I have and sometimes running for hours this can take a decent amount of battery life especially in the dead of winter. In addition, it can check for errors. Codes, then swipe them to turn off those pesky dash lights! That makes it worth it for its price in my opinion. It differs from its cheaper counterpart in that it displays 4 things at once, compared to 2 in the cheaper version. And don't worry about some of the old feedback about needing a firmware update. Now they are shipped with the latest version. Installation is also incredibly easy. Just plug into the OBD II port and start the car. Velcro is included for attachment if you don't have a windshield suction cup mount. You can connect the cable to either the side port or the rear port, whichever works best for your chosen location. /gear temp, tire pressure, etc., etc. then get it! You will not be disappointed!
