Hi All,
I didn't get any responses from my last 2 posts about setting up A/C wiring, so I thought I'd try a simpler request specifically about the tuning software only.
Does anyone have a description of the options for setting up the A/C in the 0411PCM tunes. I need to know what setup each selection is for, and how it controls the A/C.
The options are:
*Serial
*Serial Cycling
*Analog
*Analog Cycling
*Passive
*Not Fitted
My assumptions so far are:
*Serial - Uses variable compressor and gets on/off signal from BCM or A/C controls via serial data
*Serial Cycling - Uses fixed rate compressor and gets on/off signal from BCM or A/C controls via serial data
*Analog - Uses variable compressor and gets on/off signal from a/c pressure sensor and/or low/high switches
*Analog Cycling - Uses fixed compressor and gets on/off signal from a/c pressure sensor and/or low/high switches
*Passive - Not sure, maybe just gets the signal when A/c clutch is engaged but doesn't control on/off
*Not Fitted -No A/C
The wiring and analog are based on the below diagram, except the Red#14 and Blue#55 pins go to the pressure sensor
