Hi all.

Have managed to get the rest of my sensors working in some way. Unfortunately the intake air temp is only one that won’t configure correctly.

Its either reading -39 or 146 when the ambient is around 22.

Have rewired the tefzel, tried two different sensors, and different analogs, pull ups etc…

Tried on 110.6 and 111.0

Sensor in question is the link g4 type Motorsport air temp

Appears that the voltage given doesn’t correlate with the table.

Is this a know issue?

Hi,

The issue you’re experiencing is due to the incorrect channel being set on the axis of the calibration table.

I checked the default settings, and it’s not configured this way by default, so it’s possible that the channel was changed accidentally.

The correct setting should be “Intake Air Temperature **Voltage** ,” not just “Intake Air Temperature.”
