ECU Tuning

First Read and ECU Unlocking with HP Tuners

In this video I discuss the process of unlocking a Mercedes ECU with HP Tuners.


A few important things to note:

  1. An internet connection is needed when flashing
  2. Not necessary to remove ECU
  3. First read and write is very long
    1. Subsequent changes are quick
  4. No credits are needed for VCM Scanner only writing
  5. Once you use HP Tuners you cannot go back to My Genius files without modifying/resetting the ECU
