Updated to V3, added partial SP10 emulation reporting pitch/roll trim position for EFIS trim indicator.
Revised manual here

The MGL2T2 connects a Ray Allen trim servo to an MGL EFIS as if it were a standard MGL servo. For well-behaved aircraft this means you can fly the AP using trim rather than directly driving the control surface with servo. Still in the early days of testing as pitch control on a mate's Tecnam Bravo (...

I favour using the screw terminal 'chocolate blocks'- RDAC cabling terminated on one side sensors terminated on the other crimp ferrules on each wire end P clips holding the cable bunches secure before fanning out into the terminal strips Document the layout and life is much easier when you have to ...

Works fine integrating a uAvionix Ping ADS-B IN receiver or similar (eg SkyEcho) into the iEFIS.

They should be 120 ohms, not Kohms.

Pull-up resistor switched ON?
Should be OFF.

Re your fuel pressure- make sure you have the fuel pressure pull-up and pull-down switches set correctly for your fuel sensor.
Older automotive 'can' style resistive sensors- PU ON, PD OFF.
Newer 912 4-20mA style sensors- PU OFF, PD ON.
UMA style 0-5V active sensors- PU OFF, PD OFF.

it is not very clear to me where are stored the screens that you are working on, when you close the desing file a different screen is shown on the page that you are editing. Re files, simplest is to either use the SIM file manager to transfer files to the SD card, or us the script library generator...

The designed/simuator RDAC fuel level sliders don't work, but the fuel level system works fine on real hardware.
Just go for it, set up the level calibration in real life- it all works!
