When connecting the V16 (or for that matter most other radios) through an intercom you are faced with a few challenges.

Signal from the intercom to the radio. You are connecting your microphone to the intercom and the intercom would supply an output to the V16 microphone input. If your intercom ...

That's a nice useful gadget. Well done...

We use the Echlin TS920 or TS921 water temperature sender for this engine.
This is a common part used in Ford and Mazda engines.
Have you selected the correct source for your sender in the setup ?

The pitch or bank servo must stay under 180 degrees of rotation. Only the Yaw servo may go to under 360 - this is why it has three calibration points instead of two.
The calibration points are used to decide on servo direction and are used during the autopilot test.

You can do a "hack" - when you ...

60V pulse does not sound like a form of digitally produced signal for RPM. Those kind of pulses tend to be nicely formed signals usually from 0V to 12V or 0V to 5V or just a ground contact (via semiconductor) requiring a pull up resistor to some DC voltage (usually 12V).

The RDAC will handle 60V ...

You would use scan chain 1 EGT and scan chain 1 cht for all of your RDAC TC channels.

EGT and CHT maintain independent scan chains. Scan chains are only relevant for numeric readouts that scan through the channels. This was the EFIS knows which channels belong together and they can cross RDACS.
