    Default E38 Idle with AC

    I am having problems with my wife's car dying at idle with the AC on. We recently purchased this vehicle and I am unsure what all the mods include, but pulled the covers off today and there are dual valve springs. I am still new to tuning, so it may be way off, and I have not messed with the VE table yet. Attached are the log/tune files, if any of you can help point me in the right direction I'd greatly appreciate it.

    Update: D9402 TM CTD disable did the fix.

    That makes no sense.... that is a bandaid and you just lost your rev matching.... The fix is something else.

    Going back and reading my first post, I really didn't describe my problem very well. The problem on happened on coastdown with AC on, however, even on coastdown without AC the idle would surge. So, I disabled the D9402 and made it to where the converter does not lock until 58mph. I will soon be changing that to 40-45.

    Mods include 224/236 .609/.607, 117+2, 3200 converter, headers, and catback.
