Custom built ECU with KTuner End User system for the 2004-2006 Acura TSX with manual transmission. This package includes a custom replacement ECU (your factory TSX ECU will not work with KTuner) along with a fully installed and tested KTuner End User system.


  • Will only work with MANUAL transmission vehicles for this application.
  • Cruise control will no longer work with this ECU package.
  • VSA is less aggressive
  • By replacing your factory ECU, the immobilizer system will be mismatched. You can either disable the immobilizer within the KTuner software and unplug the immobilizer so the light does not blink on your dash -or- take your TSX to your Acura dealer and have the immobilizer system re-synced to your vehicle/keys to restore proper immobilizer operation.  More info here: KTuner Immobilizer Info


What else do I need to use this ECU?

  • Laptop computer running Windows XP or newer Windows operating system
  • Internet connection when connecting to your ECU for the first time to register your system and setup a KTuner account (free). To see what is involved in setting up your KTuner account, see the KTuner getting started guide here.

Bluetooth option:

The KTuner Rev1 End-User board accepts the KTuner Bluetooth Add-On Module.


Ask a Question
  • is this pug and play ready to go or does anything else have to be hooked up as in the picture i see an extra harness hope to hear from you guys soon

    The ECU can be plugged in directly in place of the stock ECU.  No wiring or other changes are needed.  The pigtails in the photo are included, but only needed if you wish to add sensors and feed them directly to the KTuner board (uncommon).
