So we got the system back together with the new pressure sensor fitting, oiled up and charged.
Again, have no clue how much to fill with so we went to the low end of the original Honda capacity (22oz).
And we got cold air out of the vents!
It was about 70 in the garage tonight, vent temp got right down to 40 and cycled off. At this point I don't if it was the Honda evap temp sensor shutting it down or the GM pressure sensor in the high side line. Vent temp creeped up to about 48-50, then clutch cycled back in. Repeat indefinitely.
Suction line was cold but discharge line wasn't hot at any point in the system.
Here's a video of the pressure gauges..https://youtu.be/t3Jde7I1UrI
Thoughts? High side pressure seems too low. It'll be in the low 80's on Sunday so I'm anxious to see how it performs and what pressures look like. I realize the cooler temps like tonight aren't ideal for diagnostics, but gotta do it when i have the free time.
Of possible important note, the way the car is wired currently, the ac condenser fans come on immediately when the ac clutch engages or when the radiator fans come on. This is a limitation of the fans I'm using and the way the system is wired (wanted to keep it simple initially). Multi speed fans are used In the original Chevy configuration (lots of wiring and relays).
This may or may not be an issue with long term ac performance. Later on I may try to replicate a Chevy style three speed fan setup instead of single speed setup.
