I found an XDF for 12587603 on NSFW's Github that has the A/C System type defined. I haven't checked it to know if the checksum is calculated properly. Be sure to verify it before flashing.

Well, this is great! If that xdf is good it solves all my problems!!! Thank you!

I'll try to set up an experiment to determine the value of that unknown capacitor. The engineer in me is itching to see if I can actually convert a "no analog ac request" pcm. Since I have an extra unit from the junkyard...

I'm pretty sure it's just for debounce, so I don't think the exact value is critical. Maybe something between 0.2uF and 0.5uF? You could probably just add the resistors to test the input. Let us know what you find. It might be a good idea to start a thread detailing the hardware differences to make the information easy to find.

Guys, i downloaded this XFD, i would like to use my ECM to control my AC, however comparing this xdf with the one used on this site 12587603 the values in the VE table show up different using the same BIN file. Am i missing something??

In case anyone needs the NOW missing files.

I think they all come from this thread.

Too bad the captain abandone the ship. So don`t expect any support for the files. Use at your own risk.

If LRT wants the files down, I will post them in another thread.

Good news is once something is uploaded on the web, you can`t take it down[delete] like it or not, it stays there.

Pay respect to the author and give him some credits for the hard work.

Thanks, kur4o.

I think LRT's XDFs were all mirrored to GitHub as well. Two people have been maintaining repositories of every XDF they could find:

https://github.com/Snoman002/Engine-...neral%20Motors

https://github.com/BoredTruckOwner/L...ine_Repository

I haven't compared them against the files that LRT posted here, but I'm pretty sure I saw LRT's XDF for my C5Z in both repos.

Anyone know why he deleted his posts?
