AI air pressure difference.

I am thinking that the pressure difference going from 350-75 was or could have something to do with a weak battery in the transmitter on the hoseless PC system. Only thing that I can think of to make sense out of the whole thing.

I've been doing some research on computers lately (in preparation to buy a new one) and noticed in reading the manual for the AI (and the Datamax 2.1) that you can set a reserve that is not reflected in the "tank pressure remaining" reading. Maybe this could be the source of your discrepancy...just a thought

I would still want to get a baseline of which one is wrong and then go from there. While I could technically 'live' with a 125 psi difference, it would still irk me enough to find out the guilty party.
