Sorry, I'm rather crap at uploading pictures lately of the rig. Will try and get some better ones soon.
I'm running an app on the iphone which connects to the PC over my home network. It picks up the signals from the game so I can see speed, revs, gear, fuel, oil etc etc. But for easy viewing I only display speed, gear and shift lights. Works really well for a free app I think its called 'Fast Dash' or something. It does have a large advert area on the screen at all times, but I have just stuck some vinyl over that area of the screen as it gets annoying!!
