There is no set "cycle time". You turn the AC on, and and the compressor circuit is energized. The cycle times are controlled by the high and low pressure switches.
The system pressure is based on the charge in the system(weight of refrigerant, not volume or pressure), engine RPM, outside air temp., cabin air temp, evaporator(inside) fan speed, and condenser fan speed(based on engine rpm for the engine driven fan) and the aux. elec. fan(whether it's running or not) <-- this mess is why no one can just say; " Xpsi is the pressure you need for a full charge"
When you're running the fan on high, the compressor stays on pretty much continuous, but again, it's controlled by the high and low switches, based on system pressure.
You sound like you're sure the system charge is correct. Have you connected a gauge set to it? (both high and low side?) Static system pressure(AC off) will have both high and low pressure switches engaged. They're easy to check with a continuity test(ohm reading across the terminals of the switch) If you get a reading, it's on. You can also jumper across the plug(bypass the switch) temporarily to see if bypassing one or the other switch will allow the compressor to come on. You can run with the low pressure switch bypassed.(not good for the compressor though) DO NOT run with the high limit bypassed.
"Max Cool" mode has nothing to do with the compressor. It shuts off outside air and recirculates cabin air.
hope that helps.
