Need some help with a few issues: tune inside

[Earl H]

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 .

Thanks mate !

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 ,
