    Default Need some help with a few issues: tune inside

    I have enclosed a copy of my current tune and a few logs. I am having a few issues and looking to see if some of the more experienced memebers can help me diagnose/fix the problems. Here are my issues/symptoms:


    - Idle hunting
    - Car dies at stoplight (1st 5 minutes of drive after warmup)
    - Car goes into reduced power mode when A/C is on and the car has been idling for ~ 3 - 5 minutes
    - Car dies when going from Reverse to Park (car not fully warmed up..coolant temps ~ 150+).

    Now I have performed a few searches, but they left me a bit confused as to what would cause some of these issues. Thanks in advance or the help.

    Car Details:

    '03Z06 TTIx Twin Turbo
    Motor: all bore LSX
    Heads: AFR225's
    Transmission: A4 (conversion)
    Operating system: COS 3 (2 Bar SD)

    Your tune needs alot of work ,

    Is your car DBW ? If it is then incresase the numbers in table c6101, this should stop the reduced power problem .

    read the custom os pdf setup it will help you out .

    The numbers in C6101 are maxed out.

    Why is your C6301 set to 210 , should be more in the 190 range with a 2 bar ?

    Also check your DTCs when the car goes in to reduced pwr , It might tell you the area that is causing the problem ,
