Hehehe! So you don't trust the electronics? How you define then "...as clean"? Let me have bigger concerns than that! Unless... you are driving a full electrical car and have solar panels all around your house and recycle the water you use on daily basis?:th_angelsmiley4:..... Although no CEL came on when you swapped to a lower temperature your car isn't burning as clean.
There are pros and cons but I work in the field and believe me not all the released products on the market are based on proven ideas and detailed tests.
I checked the thermostats for major passenger cars today and tell me if you can find one that is opening over 100C! I couldn't find any! Ideally I would put a thermostat that opens around 90-92C max but couldn't find a direct replacement and didn't want also to change the housing, adapters etc. I'm not going to argue more about "performances & emissions", I just shared my work and the results so others can decide if they want to do or not the swap since the gauge for coolant temperature is useless and you boil the coolant without even knowing it, zero warnings! :wave:
