Looking for advice. Second EMU pro install where IAT and EGT haven’t worked.

IAT to Ain and analog ground  
Cal table set up, voltage seen by ECU which correlates to expected temperature but no display of temperature. Tried new sensor too.

EGT to Aip and analog ground  
No voltage seen by ECU and no temperature read out. Tried swapping wiring round but no luck

Done continuity through wiring loom to confirm it’s an ECU/software issue.

It’s strange it’s 2 installs that have the same issue. Especially IAT that sees voltage.

Did you copy paste or load tables? You may have changed the axis on the voltage table

Is the input the IAT is wired into assigned in the software as the IAT?

If you have corresponding voltage seen in the ecu it sounds like the sensor, wiring and ecu are working

Check logging setup. If is turned off there you wont see temperature

Very short log but shows IAT voltage but no temp and EGT not working but assigned.

Thank you
