I installed the JB4 mobile app on my phone today. I ordered it separate after I realized I could not change the Maps without it. I connect the Blutooth setup and the only readouts I am getting are Boost and Mapp Setting.
RPM, Ign 1, AFR, IAT all reading 0 or 0.0. Please advise.

You need to install the OBDII to get all of those readouts.

I don’t think there is a difference for our cars. If you had the 3.3, it’s one for each turbo.

Okay. That's what I thought?

Having the same issue but on a GT2. I installed the OBDII cable and everything. Had all the read outs the first time I started the app but disappeared once the app accidentally went to the background. Any advice?
 
I should add that I don't have the fuel control wires connected yet. Lost a posi tap tip so waiting for one to arrive tomorrow
 
Have you tried shutting the car off, letting it “go to sleep” (move the key fab far enough away from the car for at least 5 minutes), then unplug the OBDII and plug it back in?

Start it back up and hopefully the gauges work again?
 
Check that the OBDII cable is oriented correctly where it connects to the plug on the JB4.

The four position square connector is symmetrical and can be connected at any clock position - it only works with one. Make sure the latch arm on the cable is on the face of the plug that has the small raised 'bump' that it clicks on to.

I'm at the point of needing readers to see close up work, and my first attempt (without them) was clocked incorrectly and just showed boost/map.
