If error code $053E appears during the programming process on your vehicle using the AutoCal, it indicates a mismatch between the VIN provided with your order and the VIN of the vehicle being programmed. It’s crucial to ensure that the VIN submitted for your AutoCal order matches the VIN of the vehicle you’re attempting to program. To resolve this issue, a new tune in .bbx file format will need to be created and provided to you. You’ll then need to upload this new tune to your AutoCal using the instructions provided below:

Program Quick Setup

The Quick Setup is the fastest and simplest method to program all necessary files for AutoCal functionality.

It includes copying the following data into the quick setup file:

  • Device settings
  • Current Options.txt file containing controllers and PID selections
  • All required supporting configuration files (*.obj, *.pmm, *.bix, and *.dtc)
  • Up to 5 *.ctz and/or *.coz tune files

To use this method, your tuner will send you a *.bbx quick setup file via email.

  1. Save the *.bbx file your tuner provided to the folder: \Documents\EFILive\V8\BBX
  2. Connect AutoCal to your PC and open V8 Scan and Tune software.
  3. Go to [F5: BBX] – [F6: Quick Setup] in the V8 software.
  4. Choose [Open Quick Setup] and navigate to the directory to select the *.bbx file from your tuner.
  5. Do not modify any settings unless instructed by your tuner.
  6. Select [Program Quick Setup] to program device settings, controller configuration, and tune files to your AutoCal.
