Here is a product I stumbled across a little while ago called the Greddy Intelligent Informeter Touch. It is a touch screen device that simply plugs into your OBDII port and cigarette lighter plug and displays up to 6 different read outs at once in various display patterns (Bars, graphs, digital, analog, etc.); featuring vehicle speed, RPM, oil temp, oil pressure, fuel pressure, water temp, boost, and intake temp. The Informeter Touch also estimates your fuel consumption, features audible warnings and it is compatible with the 06+ GD3 along with the 09 GE8. It works with several Japanese makes, but is not available for European or American models.

Edit: This device also reads and clears diagnostic codes.

Here are links to a few images of the Informeter Touch.

And a youtube video of how to use the device.

 

thats actually pretty sick

 

idk.. seems boring.. you can only see 2 things at a time

 

You can actually see up to 6 things, check out the video and you'll see.

 

So if you want coolant or oil temp you have to buy an additional harness???

 

looks good. how much are these things? (not that im going to get one)

 

Yes; you'd have to buy the sensor adapter, temp sensors and harness.

 

Doesn't Scangauge offer those without an extra harness?? Granted the greddy looks way cooler lol

 

scangauge doesnt do boost
