Anyone have this problem besides me??? I disconnected my MAF to do a VE tune and my AC quit cooling. After much frustration---I reconnected MAF and now AC cools. What's wrong????

In one of those tunes the a/c is probably being kicked off due to the pids in the OS tab or the iat pid is set at a very low temp, hence ac wont be commanded on. I am work and dont have hpt to look at, so not exactly sure where those are at. Check engine/general/iat

Anyone else experience this? I would love to work on my VE tune and have AC too!!

Guys--its 96 degrees outside and I would like to have AC to work on my VE tune. If I disconnect the MAF while the car is running, the AC works. If I disconnect the MAF while the car is not running, and restart, no AC. I am going to post my scan config so perhaps someone can tell me whats wrong.

You're not by any chance piping the wide band signal through the AC pressure sensor are you?

No---no wideband installed yet---using factory narrowband.

Try logging the AC pressure PID(s) as well as the AC status bit. Anything AC related in a log would help.
