If I am using the 2.2K ohm to fix CEL, can I still use a Pyrometer guage?

On the other hand, Is this Guage really necessary or a waist of money?

the oem egt gauge uses a thermistor. this is a resistor which changes resistance wrt temperature.

"real" egt gauges use thermocouples. these generate very small voltages which change wrt temperature.

they are totally different mechanisms to measuring temperature, and as a result are not compatable at all.

if you fit an egt gauge to your rex, you will not use anything related to the oem egt setup.
