The KTuner Revision 1 End-User board tuning system for use with K series engines allows engine tuning of K series engines by any end user (this is you if you are reading this). The KTuner End-User board system consists of a circuit board that is installed into your ECU along with software for use with the board. The system is tunable via laptop with a simple USB cable connection. This will allow you to reprogram your ECU for performance gains and to get the most from your engine modifications. Many engine basemaps are included with the software to choose from to begin with. You can even start with one of the KTuner Reflash files, then tune or make changes from there as desired. See the links below for features on each application:

** FREE installation into your ECU when purchased from us **

Installing the KTuner End-User board into the ECU requires professional, surface mount component soldering skills. We HIGHLY recommend you don't attempt the install unless you are very experienced with surface mount soldering. To make sure you have a trouble-free experience with this system, we offer to install the system into your ECU for FREE when purchased from us. This board is designed to be used with any of our HA Motorsports KTuner prepared K series ECU's, or your own ECU if you'd prefer to send yours in for installation (please check at the application links above to make sure your ECU is compatible). For a simple, all in one solution, see our KTuner End-User ECU packages!


  • One KTuner end user board
  • One KTuner end user software license (paired with system). The KTuner software can be downloaded here.
  • Pair of KTuner decals
  • New USB cable for connecting to the system
  • Free installation into customer provided ECU, or into one of our KTuner ready ECU's. See below for information on sending your ECU to us for installation.

Bluetooth option:

The KTuner Rev1 End-User board accepts the KTuner Bluetooth Add-On Module. We can include this with your new KTuner End-User system when you add this to your order.

Ask a Question
  • Is there any guide/instructions to install the tuner onto the ECU on your own?

    The install is straightforward, but requires surface mount component soldering skills.  Here's an overview of the install: http://www.ktuner.com/KTunerHelp/hardware_installation_3.htm?ms=AgAABQ%3D%3D&st=MA%3D%3D&sct=MA%3D%3D&mw=MjQw  Please note that installing yourself will void the warranty on your KTuner board.  To retain warranty, please have installed by an authorized KTuner dealer.

  • I have an 06 rsx type s and got another ecu for an 05 rsx type s as well. Can I send the 05 for the chip and will it be compatible with my 2006 rsx?

    Yes, this will work in the 05 ECU and can plug into your 06 RSX.  You will want to disable the immobilizer though in your tune/calibration file though unless you have the new ECU programmed to your keys/immobilizer.

  • I have a 05 RSX Type s if I buy this product my Immobilizer would works normally?

    If configured properly it can, or you can disable it if desired. All the info on this here: https://www.hamotorsports.com/pages/ktuner-end-user-board-immobilizer-information


  • I have an 05 MT Base RSX and was curious if I had to send in my key and immobilizer with the ECU?

    ECU only.  We don't need the key or immobilizer.  Thanks,

  • Dose the k tuner chip come with all the hardware to install in the wiring to be able to run into my laptop

    The USB to connect to your laptop is included.  If your ECU isn't already socketed for the KTuner board, you will need to add the KTuner headers/socketing kit to your order and solder those into your ECU in order to install.  We install this into your provided ECU for free when purchasing the board from us, so we highly recommend shipping your ECU to us for the install, rather than trying to install yourself.
