Hi,, I'm new here , I have 08 Avalanche with predator U1794 Ver. 9r05
I already modify my tune after I do some Log and I get on LIFT Bank1: -2,925 ,, So I just go to Injector Slope and add +3 on it

The Q's is,, What should I do with PE WOT & Spark WOT ??
How can I Know the best choice for my car ??

Note : I recored my log on 140/Km and the rpm mybe on 2300

yeah...

it's better to get those things dialed in with a custom tune, that's "the best choice for your car"... contact me if interested...

also, you said your LTFT bank 1 was -2.9xxx.. what about bank 2??? you did log both banks, right??? you need to...

and if the average ltft's for bank 1 were -2.9xxx, you should adjust your slope by +2, not +3...

but, if you didn't log both ltft bank 1 and bank 2, then you need to do a new steady driving/cruising log, and make sure you log these parameters:

air fuel ratio (Equivalence Ratio)
commanded throttle position
engine speed (RPM)
intake air temp
long term fuel trim bank 1
long term fuel trim bank 2
MAF Sensor Mass Airflow
spark advance
total knock spark retard

I will check out your logs when I get home from work in a couple hours...

do not do anything until I look at the logs and get back to you.
