# Unknowingly, I've driven Max for almost 2 years without a thermostat at all and no problems nor improvements whatsoever. n/m

: Comment being;
: Let's say a cooler thermostat was installed, would it have any adverse driveabilty problems. If the ECU is looking for 190*F to know it's at operating temp but only see's 170*F (or what ever cooler thermostat you installed) would it do anything to the ignition and fuel curve trying to bring it to that 190*F. How about the cooling fans, since the ECU turns those off/on how will the cooling fans be effected. Or is the ignition and fuel curve based more on the 02 readings?
