I've read several threads on this and I can't seem to find a definitive answer for the serial data issue. I have a 95 240sx with an lq9 swap, but the PCM was a serial data A/C trigger. Is there any way to cycle to compressor properly with this setup. Is there a non-auto a/c non serial data flash available for this? I'm not worried about the extra fan current draw and PCM controlled fan cycle like a lot of people I've seen I just want A/C again.

The old A/C was a 12v trigger and a variable displacement comrpressor with a simple triple pressure switch and worked great.

Any help would be appreciated. Thanks guys!

Which PCM are you using?
For most of them the answer is yes it can be changed.
Have you ask on SilviaV8, since that's where most of the 240sx swap guys seem to hang out

I can set the AC system up correctly to work on 12v input

Ah cool! I wasn't real sure on it being able to be switched. I have the PCM out of the 2003 lq9 from an escalade that's in my car. I have a build thread over on silviav8, but a lot of the engine and tuning specific stuff is reffered over to here

Thanks for the input guys! I will have to contact mike at vengeance and see if he changed it on my PCM or if he can with EFIlive. I can't remember if I asked him before or not, but my past research hadn't revealed a good answer for me .

Thanks again for helping clear it up!
