I saw this thread while poking around and thought I'd revive it as I've just decided to go this route in my 50 half ton.
I'm in the middle of swapping a 69 frame, blown LQ9, and 4L80 into my 50 AD. Rather than retrofit a bunch of digital gauges into the dash, I planned on using an AVIC N4 motorized 7" navigation unit and HKS's CAMP 2 monitoring system to display gauges.
The N4 is a little dated and more complex than needed. CAMP 2 is a great system. It reads OBDII information and is expandable to read other temp sensors, boost, etc. However, they do not offer a wideband option.
I've been needing a reason to buy an iPad, and I think I've found it.
Take this

with some its extra sensors (A/F, boost/vacuum for me)

throw in an app to put it all together -

and viola!
I'm stoked. I like that I can use my phone if I don't want to lug the iPad around with me. Real time read-outs and data logging done by wifi. Plus, all of the great features of the iPad. Music storage, turn by turn navigation, etc.
I'll try to keep this updated as I figure out how I make this look decent in a 1950 pick up.
Anyone need an AVIC N4 and HKS CAMP 2?
