Fixed my txv hunting issues and increased system capacity. I achieved almost the same btu at 54*F ambient, as I was getting before in the mid 70s!
Thanks for sharing your results.

Is there any way that you could show with photos what you mean regarding, "The heatpump coil, which I was using, had the suction coming off the air downstream of the coil..."

This is really good info that everybody needs too understand.

Great work!
