Has anyone had luck getting the real time misfire count or fuel pressure gauges to work with their truck on this app ? (2006 3.0)

 

Haven't tried fuel pressure, but I definitely can't get a misfire count on my '99 5.0 setup. I think it may just not be supported by the Ford ECM's from that timeframe.

 

Here's what happening guys. At idle, the needle is vibrating and fluctuating from 16-15 in/hg of vacuum. I'm at elevation so it should be close to normal, being 5 inches below normal. The fluctuation is worrying me however, and it tends to drop half an inch randomly
