Looks like it. Tunercat has it as just an Auto Air Recirc enable/disable.

Looking at your bin with HP Tuners a couple things I see. First is you have the Fan 1 and Fan 2 turn on temps set to the same temperature. But that is not what is causing your problem. Lots of GM...

Can you post the bin file you are using?

Way to go. It's refreshing in today's day and age to see someone thinking outside the box and engineering something like that. We seem to be living in an age where people just want to watch a YouTube...

I don't know if you can just "unplug" only the CMP on a V6 like you can on a V8. I just don't work on those like I do the V8s. Is there a separate plug on the distributor for only the CMP signal?
