Brian, I've played around with this as well on my 03 but have not gotten the vent temp below about 46.
What pressure are you seeing on the Tech2? According to the WIS, the compressor cuts out at a high of 27-29 bar but is supposed to kick back in at 22-24 bar. I'm never seeing pressure above about 15 bar. Apparently the 2002 cars do not have the evap temp sensor installed, it's a fixed resistor giving a fixed temp.
