The highest temp thermostat ORiellys had was 187 and that's what I put in. I don't have a way to read the setting for closed loop. It should be factory unless the guy that deleted VATS changed it. It has gone into closed loop occasionally at 160 or so. How many temp sensors are there on my LS? Could there be one that I'm reading on Turbo Pro and another that engages closed loop?
