A/C input

Post by TimH »

My Subaru S6 PnP, by default, takes the air con control in. I've had a quick look through SCal and can only see it used to increase idle rpm. Is it used for anything else that I've missed?

If not, I may well re-use the input for other things.

increase idle, increase base duty, and turn on the A/C compressor output after it's raised the idle.

However, you will need to bridge the pressure switch if you want to use the actual A/C switch as a useful input.

Thanks Paul. My Cal has no "adders" set for A/C, but fair point about the A/C output control as I missed the obvious (no change there then lol).

I can see that the A/C output has off/on engine speeds and throttle positions, which makes sense as I know my A/C turns off when driving hard...so will ponder whether to simply drive the pressure switch via a relay and decide myself when to turn the A/C off or maybe just use an engine-speed output function to "gate" the relay to give some degree of automation.

What are you trying to do? The nitrous strategy can do a lot.

Just free up an input - only one that seems a good candidate is the A/C input.

Taken a quick look at the NO stuff and can see that has all the control I should need....just a question of whether A/C control really needs to be smart or if simple on/off will suffice?

SO you don't have a spare ignition output that you can hook up to a regular ignition amp to turn it into a high level output?

Lol, yes Paul, trying to free up an input :)

Is it worth trying to semi-automate the A/C control using the NOS strategy, in your opinion, or shall I just bridge the input to the AC pressure switch and be done with it?

You could grind off a tooth from your cams and use your AVCS sensors to get 720 sync like a hawkeye, although the earlier sensors don't put much voltage out at cranking speed, although you could also change the sensor if you're keen.

Have you ditched your cal input yet? ;)

grinding teeth of cams is a bit excessive for A/C lol.

Perhaps you've muddled replies to 2 different threads :)

If the CAL input question is aimed at me then no, not yet. I have implemented CAL up/down, but the S6 complains about the other missing M4 packets and I am awaiting guidance from Syvecs/LR on how best to deal with this without (further?) upsetting the vehicle and/or S* ;)
