why would a thermostat change cause a CEL?
it might not be too helpful in cooler months but i've been contemplating a thermostat swap for mine for a while. other than that, i would like to take control over the fans and crank them on at a lower coolant temp but that requires uprev.

my quest to find a coolant temp sensor that had different scaling was futile also.
even if i found a suitable one, the sensor is in a very awkward spot to reach. easier to wire up a switch to kick the relays on

Because it will take the car too long to warm up and the water temps will fall too quickly and you'll get a CEL

The car has certain presets built in, you can "overcool" the car and cause a CEL if it does not warm up fast enough.

On the venting side:
-Vented hood
-Vented fender liner (GTM sells a prefabbed one but you can DIY it)
-Undershroud
-Better heat management (Wrapping intake pipes, headers, etc)

Cooling:
-Tune with fan speed adjustment
-Radiator upgrade
-Radiator fan upgrade
-Oil cooler
-Radiator fluid swap (doing a blend of antifreeze & water)

The ECM takes a look at your ECT's and your IATs to determine if your thermostat is doing what it should. If this check fails it will trip a code.
