Yep, 185* thermostat just means the coolant moves through the system. Doesn't do you any good if the system can't cool it down which on a hot summer day requires moving air from the fans.

I can do it, but you need to ship the PCM to me. It would need to be a shop with the right software. A place with a dyno might be able to.

looks like your temp sensor is malfunctioning or your radiator is plugged. Have you tried going for a spin for an hour or so?
