Turbo vane pos won't go any more then 45%. I can command it with my snap on tool and they will go full close and full open so I know its not stuck vanes so I have a feeling my tune has something going on with it I've messed with every ebp table and airflow table to try and work it out myself but its beyond me what's going on if anyone feels like taking a look here is my file and log.
You're making a ton of power, can you log more pids about the turbo and its commanded vane position? Just get as much as you can and get a 10# min log
Yeah ill mess with that pid list and get you some more info.
Looks like that log I have is the best I can do, there isn?t any more pids for me to log and the duty cycle I have logged is basically the pcm commanding it
Is there a specific issues you're trying to fix?Originally Posted by AustinR96
Just want the truck to use more then 45% duty cycle on the turbo vanes. The truck is numb down low and smokes on take off until the turbo finally lights. I've looked any many other 6.0 tunes and they are similar to mine so I'm not sure that's its a tuning issue or maybe i have something electrical going on, but wanted to at least have someone tell me that the tune looks okay and that its not normal for the pcm to be commanding 45% when my tables have around 80% commanded in the lower rpm range
OK, let me look it over; I use a different turbo configuration and am not familiar with tuning the vane openings.
Walk me through the log, where does it get sluggish? I see the EBP and ICP kind of low but walk me through the log here.
