ScanGauge II

I just bought and received my ScanGauge II from Amazon. I got it for a few reasons, one of which being that my wife's Mazda 3 will throw a CEL if the gas cap is not on EXACTLY as Mazda intended it to be and I got tired of taking the battery cables off... Whatever the case may be, I have one and I am going to start using it on my car.

WHERE TO MOUNT
-Information about mounting above rear view mirror
-Installing ScanGauge on left side of steering wheel ('07)
-Combination thread of different installation locations

WHAT DOES IT ALL MEAN
I'm not super savvy when it comes to my FXT but I know enough to get me by. The ScanGauge II offers readouts on all sorts of information. However, it is not all useful unless you have a benchmark of what to go off of. So, if you know the standard temperature/pressure/timing/etc. of the following, please reply with the number, for what year/model and I'll update this post:

FIA/CIA - Intake Air Temperature:
FWT/CWT - Water Temperature:
FPR - Fuel Pressure:
IGN - Ignition Timing:
MAP - Manifold Absolute Pressure:
VLT - Battery Voltage:

XGAUGE
The ScanGauge II offers some features only available for the ScanGauge II v3.14 and above - mine came with v3.17 (check by clicking MORE>MORE>MORE>VERSION). These new features are called XGauge and offer such things as:
-Displaying instantanous Horsepower readings
-O2 Sensor
-Air/Fuel Ratio
-Engine/Transmission Oil Temp
etc.

For these, there is a PDF located HERE that allows you to enter codes for car types for the different readings. Our car uses the ISO car-type codes (thanks 2.5x_sleeper). I haven't tried it but it's document on the ScanGauge website.

UNPLUGGING
I found out the first time I went to unplug it that it doesn't come out too easily (at least initially). I got a pair of pliers and using a cloth, clamped on and pulled to remove. I intend on getting a second cable to use with other cars, but in the mean time, I'll be unplugging it that way.

We have the Scangauge II installed in all our vehicles. Normally the SG2 is set to "GAUGE" function to display MPH (digital speedometer), battery voltage, intake air temp & coolant temp. If I get a CEL, I use the "SCAN" function to see what code is stored & clear it. Other than that, I really don't need the other functions, so I haven't used them.

2.5x_sleeper: I read many of your posts about where you put it and such before buying. Thanks for all your input. That's partially why I made this post, so I could combine a lot of the other threads

I'm still deciding on where to put it. I was going to put it in the small sunglasses compartment but it is sort of an awkward place to look. I think I'm going to go for the left-side of the steering column.

Ideally I would get one of those and then get a flat RJ45/CAT5 cable to run:


On another note, can anyone say what the typical readings are for these gauges?

FIA/CIA - Intake Air Temperature: ?
FWT/CWT - Water Temperature: ?
FPR - Fuel Pressure: ?
IGN - Ignition Timing: ?
MAP - Manifold Absolute Pressure: ?
VLT - Battery Voltage: ?

Does anyone know if our car is ISO, VPW or PMW? That is used in the XGauge code...

The Scangauge II only needs 3 connections for it to work on the Subaru. At the OBDII end, here are the connections you need:

3&4 = Ground. These are the longer pins in the plug and are shorted together in the connector.
16 = 12V
7 = ISO K

At the other end, looking at the side with the contacts, with the cord coming out of the bottom, the pins are numbered 1 to 8 from left to right.

Ground = 1
12V = 8
ISO K = 6

You can easily extend the cable by using a standard data cable.

As to where to place it. I wanted mine where it was easy to see & easy to remove, if needed for theft prevention.

can Scangauge display KPH and KPG ?

i have never bought a single aftermarket gauge or electronic device to show me any readings.

what is the absolute minimum of devices needed to satisfy your needs?
and where does scangauge2 stand on your list?

06 XT, yes, in silver

Scangauge is all I have, and all I need. Won't be buying any other gauges :)

Ah I see. We don't hear that over here :)

I don't think it can, but could be wrong.

could it be those two units one must have?

It has something like 6 presets, but you can custom create a color by increasing/decreasing blues, greens and reds (I think).

So does anyone have any figures for what these should read? I'd like to update the top so that people can get an idea of what these should read:

FIA/CIA - Intake Air Temperature:
FWT/CWT - Water Temperature:
FPR - Fuel Pressure:
IGN - Ignition Timing:
MAP - Manifold Absolute Pressure:
VLT - Battery Voltage:
