When you run under 160deg ecu will be open loop. I ran with different size washers trying to get the right temp.

Opens at a lower temperature (169F) than standard thermostats, allowing coolant to flow through the engine sooner, reducing engine temperatures
my S13s temp gauge sits right around 168-172 (via upper radiator hose temp sensor) when im driving and is rated at 169 (just looked it up). i highly doubt the Mazda will fall into closed loop after its warmed up.
