Product Description

Product Description

The ScanGaugeII is a compact vehicle computer that connects to the diagnostic connector in seconds and gives you an extensive trip computer, real time gauges and trouble code reader. It can read fuel economy as you drive, tell you how fast your friend drove your car last night, tell you when you are going to run out of fuel and dozens of other functions. Installation takes only seconds and requires no tools. It can be moved from car to car. Works on gas, diesel, propane, and hybrid vehicles. The ScanGaugeII works on all OBDII protocols including the new CAN protocol.

Amazon.com

The ScanGaugeII is a 3-in-1 automotive computer that combines a multifunction trip computer, diagnostic scan tool, and up to 37 digital gauges in one small package. It connects easily to your vehicle's On-Board Diagnostic (OBDII) port and communicates directly with the vehicle's computer. Not sure if your car uses OBDII or Controller Area Network (CAN)? The unit will automatically determine which system to use and switch to it. The ScanGaugeII works on all 1996 or newer OBDII cars, including gas, diesel, propane and hybrid vehicles, as well as vehicles with the latest CAN systems. A detachable cable allows for easy transfer between multiple vehicles. Its menu-driven operation means there's no need to memorize complex sequences, and no tools are required for installation.

Expandable Add-A-Gauge Technology
The ScanGaugeII has been redesigned with expandable Add-A-Gauge (aka XGauge) technology. Add to the original 12 gauges by customizing the ScanGaugeII to monitor up to 25 more--depending on your specific vehicle's sensor design. Four gauges can be displayed simultaneously and can help determine fuel consumption rates, allowing you to adjust driving behavior and save gas. At the same time, keep an eye on coolant temperature, engine speed, and much more in real time. If there is a young driver in the house or friends borrow your car, the ScanGaugeII can record speeds of up to 158 mph and store the information for you to view later, so you will know just how fast your young driver or friend was going last night. If the unit was disconnected, you'll know: An indicator will be displayed in the trip data.


ScanGaugeII mounts easily to your dash.

Gauges include:

  • Horsepower
  • Fuel Consumption Rate to 1/100th per gallon/liter
  • Vehicle speed (MPH)
  • Fuel Economy
  • Cost Per Mile/Cost Per Trip
  • Manifold Pressure (not available on some vehicles)
  • Battery Voltage
  • Engine Load
  • Coolant Temperature
  • Throttle Position
  • Intake Air Temperature
  • Ignition Timing
  • Engine Speed (RPM)
  • O2 Sensor Data
  • Fuel Trim
  • Hybrid Battery Charge (for Toyota Prius and Ford Escape)
  • And many more, depending on your vehicle's sensor design

ScanGaugeII makes diagnostics easy.

Scan Tool
The ScanGaugeII includes a diagnostic scan tool that can check for Diagnostic Trouble Codes (DTCs), clear the codes, and turn off the "Check Engine" light on 99% of 1996 and newer vehicles. (However, this feature may not work on some trouble codes in Dodge vehicles.) If any DTCs are found, the ScanGauge will show how many there are as well as the codes themselves. Then you can use the Internet or repair manual to find out which is the failed part is, so you can repair it yourself or know what needs to be fixed at the mechanic's shop.

Multifunction Trip Computer
Four sets of data are automatically recorded on the trip computer: Current, Today, Previous Day, and Tank Trip. The "current" trip restarts after the engine has been off for more than 3 minutes. The "today" trip restarts after the vehicle has not moved for 9 hours, and the data from "today" is moved to "previous day" when you restart the car, so you don't have to reset the computer every time you begin a trip. "Tank trip" resets when you fill up the tank. It can provide you with "to empty" data and other useful information, which can be viewed any time during the trip. The trip computer also integrates information from the Cost Per Mile gauge. Simply enter how much you paid per gallon or liter of fuel, and the ScanGauge will automatically calculate the cost of your trips as you drive. The ScanGaugeII features 12 individually stored parameters, including:


ScanGaugeII features 63 backlit colors.

  • Fuel to Empty
Personalize It
A large, high-contrast LCD display makes viewing the information easy, and both the display and keys are backlit and can be set to off, low, or high. With 63 possible colors, user settings, tank trip data, and vehicle settings that are automatically saved, and up to 10 user commands that can be stored and recalled, the ScanGaugeII can be easily customized to suit your needs.

Customer Reviews

Good product, easy to install and set up, works great.
R. G. Demott
I wanted a real-time mileage readout to be able to tune my driving habits for best MPG, and I also needed a transmission temperature gauge for trailer towing.
Scott M Reese
After trying out the ScanGauge II, it's proven already to be a great product and well worth the money.

I have had the Scan Gauge II in my Toyota Yaris for about 3 months now, and have tested it's functionality in a wide range of city and freeway driving. Since the car is only a year old, I haven't needed to scan any trouble codes yet, so I am using the SGII primarily as a fuel economy computer.
SGII connects directly to the OBD-2 diagnostic port that is present on most vehicles sold in the US since 1996. The manufacturer, Linear Logic, publishs a list on the company website showing specifically which makes and models of cars and light trucks that the unit will and will not work in.

Features: The SGII reads the data stream from the car's engine control computer, and uses this data to calculate and display, in real time, the engine's fuel consumption, RPM, coolant temperature, throttle loading, and Trip/Tank statistics like how many miles you can go on remaining fuel, and how much $$$ worth of gas has been burned on the current trip. The unit offers something like 40 different functions and guage displays - go to the company website for a complete list.

What I like about the product: Adds fuel economy displays, plus some other guages like Water Temp and RPM, that weren't available even as options on my Toyota Yaris. The fuel economy computer feature is something that you usually see only on up-scale cars costing over $30,000 - ScanGuage II adds this functionality to almost any OBD-II complient car for only $159. The Yaris fuel guage isn't very accurate, whereas the SG-II tells me to 1/10 of a gallon how much gas I have left. At each fill-up, you can re-calibrate the SGII with the exact amount of gas pumped.

This little box is very useful. In my case it already paid for itself. I was able to clear some service codes (misfire of a cylinder). In the past I paid $69 for the mechanic to just look up and clear the code.

I really like the fact that ScanGauge displays all kinds of engine data in real time. Other devices such as the CarChip save it and then need to be connected to a computer in order to access the data.

In my opinion, the ScanGauge is worth every cent.

I've had the scanGuage II for about 3 weeks at the time of this review. I had bought the unit because I was interested in finding out about how my car, a 2002 Toyota Solara was holding up and what the car computer might tell me.

First the cons:
1. The cord is too long. The total run from the ODB II port to where the unit is
mounted is about a 15 inches, top. It would have been nice to have sockets
on both the plug and the SG II. Include a long and short cord, or just have it
so that cat5e network cable could be used.
Why? Because storing the excess cable somewhere is a problem, I ended up
storing in inside the panel protecting the steering column, and may have
created a short in one vehicle lighting circuits.

2. The velcro is too weak to hold the unit in place. I ended up using Radio Shack
LockTite fasteners (the clear ones) instead.
3. The manual leaves a lot to be desired, especially the pictures which are so low
contrast and dark they are useless. I had to go online and download the
manual as a PDF file.

Pros: The ScanGuage works as advertised. To me this is the Holy Grail of
advertising. It barely is worth repeating the items for sale that deliver what
they promise.

1. The display is large and very legible, even at night (or especially at night).
2. The diagnostics (both realtime and stored) are comprehensive
3. The codes are easy to read.

The biggest pro for me is being able to monitor my actual Miles Per Gallon
*mileage* I've changed my driving style from constant foot on the gas
pedal to gas-and-coast. A tank of gas lasts SO much longer now, because I
now know how much a lead foot costs.

The installation of the SG2 is simple: attach the OBD2 connector to the DLC port and attach the RJ-45 jack to the SG2 unit. Routing the cable is really up to the operator. I chose to do it in a crude manner because I don't plan to make it a permanent addition to the car. I zip tied the cable to my HVAC vents and anchored it to the empty traction control hole behind the glove box.

I used 1 of the provided velcro kits to affix the SG2 to the top of my steering column so that it is right below the instrument panel. It actually blocks my view of the shift indicator array, although I can still see it clearly if I lean forward.

The update rate set at FAST is still rather slow and that is to be expected with the outdated OBD-II network. The "fastest" aftermarket scan tool that I have seen is SCT's Live Link for Ford / GM / Chryslers. If you want anything faster, you are going to have to borrow an OEM's scan tool system.

The X-Gauge interface is a bit cumbersome since you are restricted to using 2 buttons to enter alphanumeric characters while if you pause for anything more than 10-15 seconds, the SG2 shuts down. According to Linear Logic, they are working on an updated SG2 with datalogging features so hopefully they incorporate a PC interface to speed up programming and setup times.

I have it set to monitor instantaneous MPG, RPM, Vehicle Speed, and a gauge that I frequently switch depending on my mood. I am monitoring the torque converter slip ratio. Whenever it reads below 1.00, it means the torque converter is "slipping". Above 1.00 means the output side of the converter is spinning faster than the input side and theoretically it could just mean engine braking with some torque converter slip.
