Using the EGT inputs for pressure inputs

[steve_izett]

Hi there

I would like to use the EMS-220 EGT inputs to interface MPX10 pressure transducers to measure and log the cowl and diffuser pressures enabling an excellent tool to diagnose cooling and cooling drag issues.
Tested OK as far as the raw data from an MPX10 interfacing to the EMS, however after creating a sensor definition and polynomial it appears I can only point the EMS EGT/CHT pins at the existing EGT and CHT definition and associated polynomial.
Is it possible for this to be changed please along with a change from Temperature to Pressure inputs.

Thanks very much

I realise I could change the polynomial in the existing EGT definition to get the desired inches of H2O on the display/log, but in doing so I lose my EGT's.
It would be nicer if I could retask the many unused EGT pins.
I've used up all the other EMS inputs and the Thermocouple inputs appear a nice and simple interface for the MPX10's differential outputs.
At $8 a sensor, I thought having such pressure inputs would be very helpful for many users trying to get to the bottom of their cooling issues or wanting other pitot air velocities.

Thanks
