Workshop workflow

  1. Read the K9K ECU via OBD or bench using your existing flasher (KESS3, AutoTuner, MPPS, Trasdata, FRF).
  2. Open Softechpro V5 and drag the .bin / .ori / .hex / .s19 / .frf onto the workspace. The Delphi DCM3.7 variant is auto-detected.
  3. Pick the service tab and apply Stage 1 / 2 / 3 / DPF OFF / EGR OFF / AdBlue OFF as required.
  4. Save patched .bin — the Delphi trailing sum is recomputed automatically.
  5. Flash via your existing flasher. Adaptation reset via OEM scan tool if required.
