Is the sensor configured the same on both EFIS?
Both set for the same units (C or F)?

I have struck a similar problem in the past, where a whitish waxy substance blocked up a fine mesh inline fuel filter. You could blow throught the filter OK while it was dry, but the moment it was wetted with fuel it blocked. It was apparently Durene- leaching from the inside of 2 new 20l fuel conta...

I found another way to skin the cat.... The current input was not being used, so I configured it to behave as a GP 0-5V input. Zeroing current at sensor minimum and tweaking the current gain to give the desired full scale value at sensor maximum, you can use it as a GP analog input and link a displa...

That stuffs up my plans!
I had asumed it could also be configured as a general purpose 0-5V analog input using the programmable probe option to calibrate it.
Would be a nice option (hint!)

Hi Rainier- I think there is a problem using the programmable probe option- in the SIM at least (not tested yet in actual hardware) iEFIS G3 SIM V 1121 (fresh download) COOLANT channel set to programmable probe programmable probe set up in equal ascending steps 20C..160C between 1000..4000 ADC using...

That's a video input window.
The left or right curson buttons will scroll through video sources to none.

You can enable/disable scanning state at power up in the first level menu.

Trapped moisture slug in your pitot line?

Black to ground, red to input, pullup resisdtor ON, set sensor as LM335 type.

Airspeed increasing as vacuum applied to the static makes sense- you are creating a positive differential pitot over static.
That also indicates the static sensor is working to some degree, as it is responding to pressure changes.
Try calibrating your altimteter channel.
