Has anyone tried this out yet? http://iracedash.com/index.html Was "curious" this evening to try it out. Already have a SLI PRO display on my G27. But there are some extra data displayed besides the rev lights such as RPM, SPEED, Best Lap, Last Lap, Lap Delta, Oil, Fuel, Water and lastly Position and Lap Count. Cool thing is when you swipe the touch screen to the left there are two other screens displayed such as Pit Fuel and Pit Tires. Wondered what the + and - did and to my surprise touching the screen added or lessened the fuel amount for a scheduled fuel stop along with different amount of fuel ranging from no fuel to a full tank. Same thing with Tires. Touching the screen allowed you to add tires pressure or lessen the value. Pressing LF unchecked it and pressing it again checked it of course. This alone makes it worth it for those that do not have a button box which helps make pit stops easier. If one were to mount it on top of their G27 to see thru the wheel, it actually looks like you have your own virtual dashboard. So for those with an Android phone and have been interested in getting a rev display along with a touch screen button box for fuel and tires, should take a look at it.
