PCMflash – 55 Module Kia / Hyundai Kefico / Denso Activation

The PCMflash Module 55 is a software add‑on for the PCMflash ECU tuning/diagnostic software that enables support for certain Kia/Hyundai engine control units using Kefico & Denso ECU types. It specifically supports:

• Kia/Hyundai 2.5 L CRDI (SH72546)

• Hyundai Euro 5 (Denso SH7058S)

• Hyundai Euro 6 (Denso SH72543 / SH72546)

  How the Activation Works

  PCMflash operates on a modular licensing system:

  1. USB Dongle (Hardware Key)

     • To use any PCMflash module (like Module 55), you must have a compatible PCMflash USB dongle (often Guardant‑based).

     • The dongle stores your activated modules and acts as the security license key.

  2. Purchase the Module

     • You purchase Module 55 (sometimes sold as “Activation” for that ECU set).

  3. Activate the Module on Your Dongle

     • After ordering, the vendor will require your dongle serial number and sometimes your registered email.

     • They will issue an activation file or unlock code tied to that specific dongle.

     • The software or vendor instructions walk you through importing this activation
