NGC or GPEC2?

I guess I was thinking that if I already had a computer in place, why not use it to control the AC (if possible). What I don't want to have to add another module, guess I will have to look further into it.

Honestly, AC knowledge is fairly weak for me beyond the basic principle of how it works. But I think most OEM EFI systems control the AC clutch so it can do thinks like turn it off when you go to full throttle. Could be that is all they do, don't know. Further research required.

Thanks.

With my Sublime harness, it does have an AC input trigger but I believe it is just that.. It allows me to utilize the factory engine harness, to control the AC wiring to the compressor. It routes through a seperate relay to keep any load off the ecm. I don't believe it turns off at WOT. The compressor that must be used is the single plug style and not the variable version, with 2 plugs. ANd turning the AC on, does not kick my fans on. My fans pretty much run constant, once it reaches temp.. so I just let it hit temp, which happens pretty quick, and then turn on AC. WHen I asked Blake if it could be set to control fans, he said it's possible through the SGA trans controller , but there's a few hoops. I could also add a relay to kick the fans on, off the AC trigger, but I'd need to add diodes so it doesn't backfeed into the ecm

Basically, you can run a wire from your panel, through a binary or trinary switch and to the compressor.
