The integrated Trip Computer provides realtime feedback while simultaneously tracking three sets of trip data. The Digital Gauges give you realtime data for your vehicle and the built-in Scan Tool allows you to read trouble codes and diagnose potentially expensive problems before they get out of hand.

Basically you plug ScanGuage into your ODB port in your cabin (not sure where in si). Then you get all kinds of great specs:
* Maximum Speed
* Average Speed
* Maximum Coolant Temperature
* Maximum RPM
* Driving Time
* Driving Distance
* Fuel Used
* Trip Fuel Economy
* Distance to Empty
* Time to Empty
* Fuel to Empty
* Fuel Economy
* Fuel Rate
* Battery Voltage
* Coolant Temperature
* Intake Air Temperature
* Engine Speed (RPM)
* Vehicle speed (MPH)
* Manifold Pressure (not available on some vehicles)
* Engine Load
* Throttle Position
* Ignition Timing
* Open/Closed Loop
Not all specs are supported on all cars, but since the Si is so modern it will likely support a bunch of them. In addition to these specs it will show you ECU codes AND let you reset them! For $169 that is a pretty bad ass piece of equipment for learning about your car and tuning.
With all that said, I don't own one yet. I wanted to find out if anyone else has used the ScanGuage to investigate their mods. I see some hits on search from users who are using it to tweak their gas mileage, but I'm more interested in stuff like:
How much difference does a CAI make to INTAKE TEMPERATURE readings on the scanguage? What about the intake coolant bypass mod?
How much difference does a SRI make to MANIFOLD PRESSURE (lol danger to manifold).
ScanGuage seems like such an awesome tool, but I never see anyone talking about specs other than dyno. Not saying that a good dyno isn't the obvious answer, just that there is more to learn with more information available. Also, for anyone that owns a ScanGuage for the Si - where is the port and where did you mount your scanguage?
