I have been trying to dial in my lsxrt manifold on my procharged 5.3. everything is perfect except when i rev it in park or nuetral. the truck will catch the idle, it just falls on its face. I have messed with idle air flow correction. but i am lost.

 

What do you mean it will catch the idle? Do you mean on return to idle it dies?

Need to adjust the throttle cracker and follower, and of course the base running airflow table needs to be correct first.

 

yes, on the return idle it dies. would you mind looking at my tune for me? i can email it to you.

 

Would anyone be willing to take a look for me?

 

What tuning software are you using? Post your tune up, I am sure someone will help. Also post a log, that will help.

 

I was having this issue and I was able to rectify it with the spark flare control and the over/under error correction.
This is in EFILive though, not sure where this is in HPT, but my settings for it are:

Let me know if this helps.

 

I am running efi live. I will post up the tune when I get home.

 

Log_0009.efi

Log_0008.efi

I am not sure why it wont let me up load the tune file. its a .ctz
But I am willing to pay if someone can help me out. I have a few other tuners try with no luck, I dont wont to bash.

 

Can you email me the tune? dwrobb99@yahoo.com I more than likely wont have time to look at it until tomorrow unless I get home tonight earlier than anticipated.

 

Plus in those logs it looks like you were in gear the whole time. I won't be able to tell unless you select the gear PID.
