PCMflash – 15 Module Nissan / Infinity K-Line Activation

PCMflash is professional ECU programming software used to read, write, and modify the firmware inside a vehicle’s Engine Control Unit (ECU). It’s commonly used for tuning, backup, repair, and custom calibration work.

The software doesn’t automatically include all vehicle support — instead, it uses modules (also called activations or protocols) to unlock the ability to work with specific ECUs.

“Module 15 – Nissan/Infiniti K-Line” is one of those modules. Activating it gives PCMflash the ability to communicate with supported Nissan/Infiniti ECU hardware that uses the K-Line diagnostic communication protocol.
