Another simple overheating-related question

Do the ECT switches have anything to do with the temp gauge readout? Could replacing them correct my fake overheating issue?

I've been researching as much as I can and it sounds like all the switches do is adjust air/fuel ratio and in some cases timing to adjust for engine temperature but I can't find a decent in-depth description of what happens if they're malfunctioning other than some ECU's are programmed to shut the car off if it gets too hot as a result of the switch readings.

Again, the list of what I've done already;

-I've flushed the system 3 times- Currently running a 40/60 coolant to water mix with Royal Purple 'Purple Ice' coolant additive.
-Changed the Thermostat to a 180 degree
-Replaced ECT sensor
-Replaced Temperature Sending Unit
-Bled the system of air.
-Replaced the radiator cap
-Performed a pressure check- held fine.
-Replaced the actual gas/temp gauge cluster

Re: Another simple overheating-related question

^ your next step should be to purchase an aftermarket coolant temp sensor and seperate temp gauge. The stock sensor/gauge is not so accurate and not specific at all.

Re: Another simple overheating-related question

When you say to get an aftermarket temp sensor, do you mean like a Duralast from AutoZone?
