I want to do this so bad don't have the hardware/sw to do it maybe that'll be my birthday present.

I drove for months with a car that rarely if ever got to closed loop only discovered my tstat didn't close when ambient got below about 10c and cabin heat stopped working. What a stupid design. On the hot side basically only indicates that you blew out all your coolant. If there is a pint left won't read red.
