Hey Woodshed.
I “bypassed” the heat exchanger.
a) at the time of install - there was no device (that I was aware of) to bypass based on coolant temp
b) Phil just announced a device just like that. Heck of a neat design. I don’t have it but it sure sounds like it’s worth investigating/ testing.
c) there is “one area of interest” on the chiller. In early driving is appears to have reduced the amount of cooling efficiency to the cabin. However, Phil’s design has an adjustable valve to divert more cooling into the cabin. Way cool. I will need to play with that as summer rolls in. Being in Houston - AC is not an automotive “feature” - it is a survival system!
