To install ProECU, download and run the EcuTek App Downloader. This will download and install the required files and hardware drivers and guide you through the installation process.


The EcuTek App Downloader is a standalone version of EcuTek Update that will install the drivers for the Hardware Licence Key and the EcuTek USB Vehicle Interface. It will also download the EcuTek ProECU software for your licence key.


  • Download and run the EcuTek App Downloader
  • Follow the on-screen instructions to install the drivers
  • When prompted, plug in your EcuTek Vehicle Interface cable
  • Ensure your licence key is plugged into your PC
  • Once the drivers are installed, the App Downloader will then download the required files to install ProECU.
