Thread: Trying to dial in my tune. 04 Supercharged 4.0 Jeep LJ

  1. #1

    Will someone checkout my tune and log.04 Supercharged 4.0 Wrangler

    Here is my current tune file and last drive with scanner, which wasnt far. I have tried everything I can think of to make it go in to open loop as soon as it shows boost(54kpa is koeo map). I am now having an issue where when the ac kicks on, the idle drops low then kicks it off. It also is hanging rpms about 1200 until I come to a complete stop for a second or so. Let me know if you see anything obvious.


    How can I force open loop instantly?

    What is causing the new ac idle dip?

    What causes the idle to hang?


    This is the only vehicle I have ever attempted to tune. Thanks in advance

    I will give that a shot. I also lowered the threshold to 54kpa as well.
