Thread: 5.3L Base Tune Help

  1. #1

    Default 5.3L Base Tune Help

    I have a bone stock 5.3L with 75 mm turbo & 80 lb/hr injectors. Have charge pipe disconnect to try tuning it in on motor first. Is there anywhere I can download a stock tune to start with? Have it running now on the custom calibration (364ci 850HP 20psi). Idles pretty well, but drives like crap. Any help is appreciated!

    That should be fine. A base calibration is what you start with to create your Global Folder.

    Remember, the base calibration you start with, must correspond to the MAP sensor you're using:
    For example, you can't use a naturally aspirated base calibration for a forced induction engine.
    This is because the 2,3,5 bar MAP sensor selection only changes the kPa load Y-axis, but not the Base Fuel Table lb/hr
    values (creating an excessively lean map) or the Base Timing Table degree values (excessively advanced timing map).
    You must choose a 2,3,5 bar base calibration or reconfigure your existing Global Folder's Fuel & Timing Tables accordingly.

    It's imperative the Engine & Ignition Parameters, Sensors, Idle & Spark ICFs are verified to be correct, before initially starting the engine.
    If this isn't a DBW application, ensure the DBW ICF isn't included in your Global Folder (Toolbox, "Remove Individual Config", Drive-By-Wire).

    A base calibration is what you start with to create your Global Folder.
    Five ICFs (software icons) are required to operate the engine: Fuel, Spark, System, Sensor & Idle.
    Program the correct information into the Engine Parameters, Ignition Parameters, Sensors, Idle & Spark ICFs. (Base Calibrations) (Quick Start Guide)! (Initial Checks & Adjustments - Read This!)
    May God's grace bless you in the Lord Jesus Christ.
