AutoCal V2 Read a Controller

Authors list

NOTE: Not all Supported controllers can be read.  Some vehicle manufacturers have disabled the ability to read the contents of a controller from the factory.  In these cases, EFILive customers will need to obtain base files from an alternative source. Some EFILive Custom Operating Systems are written to non-readable memory.  These files cannot be read from controller.  Refer to the Problems Reading a Controller  article for further information.

Follow these steps to read the selected controller.

AutoCal Simple Menu:

  1. Install AutoCal BBX configuration and tune files provided by your Tuner if not already setup.
  2. Connect your AutoCal device to your vehicle.
  3. Turn the vehicle ignition to the On or Accessory position (vehicle must not be cranked/running when reading).
  4. Navigate using the arrow keys to the Read menu option.
  5. Select the correct controller type from the previously configured BBX controllers in the Read 1-5 options. (NOTE: Unused Read options are hidden on the AutoCal Simple Menu).
  6. Click the OK button to initiate the read operation.
