It does. Thanks for all the help man. Also glad to hear its been working well for many years. Will make up one of these harnesses at work this afternoon and try to dabble with it this weekend. Thanks!

Was also curious if you could elaborate on this point. As it seems its slightly different logic than your recent recommendation (of targeting a 38* cycle start temp). In the above, you targeted 38* steady state? But then raised resistance to get the voltage across the terminals to 2v? Why? And why did this produce a cut off of around 34? Thanks for all the help man. This seems like it will transform the system to operate much more like a "normal" car

Understood. Given I dont have a set of proper gauges (just a low side pressure/charge hose) ill have to rely on vent temperatures to adjust. Is targeting a VENT temp of 38 too aggressive? Or is that the method you used as well? I also have no idea what vent temp it produces as is, and I’m trying to judge how much temp delta will be on the table after properly adjusted. Did you happen to measure your initial temperature before targeting 38?

OP, when you're calling out these temperatures, are you referencing an arbitrary vent temp measurement? Or do you have a means to reference the actual measured temperature reported by the ambient temp sensor? Just trying to understand what the actual "tuning" process looks like and what tools are required. Thanks!!
