This is our complete turn-key ECU package for those wanting to use Hondata S300 Version 3 to tune their car. Includes an HA Motorsports specially prepared OBD1 P28 VTEC spec ECU with fully installed and tested new Hondata S300 Version 3 system. For those who'd like to use the boost control features of the S300 software, please select "ADD PWM BOOST" from the drop down menu for this to be added to your ECU package.

ECU Casing Option: We have two ECU case options for you to choose from:

  • Standard Case: This is the standard bead-blasted casing. This is a clean, like-new finish to the standard ECU casing. (see photos)
  • Powder Coated Case: This is the new option to have the casing powder coated in our hammertone grey just like the ECU lids. (see photos)

ECU Covers Option: We have two ECU cover/lids options for you to choose from:

  • Standard Covers: This is the standard powder coated grey top and bottom covers.
  • Clear Covers:  This is the upgraded clear top and bottom covers.  With this option, we will ship your ECU with the clear lids installed instead of the standard powder coated covers.

PWM Boost Option:  The S300 software allows the control of turbocharger boost pressure when used with an electronic boost control solenoid.  This requires the boost control circuitry to also be added to the ECU board in order to function.

  • No PWM Boost: Choose this option if you do NOT need the PWM boost control circuitry added to your ECU.
  • Add PWM Boost: Choose this option if you want the PWM boost control circuitry in your ECU.  This will allow you to control an electronic boost control solenoid directly through the S300 software.  If you do not need this yet, but would like to use the PWM boost option in the future, add this option now so that it will be in your ECU and ready for use when you need it.

Ask a Question
  • Does this ECU include a basemap?

    The S300 Version 3 requires the end user to register the system and agree to the Hondata terms before a basemap can be uploaded.  For this reason, we do not upload basemaps to our S300 ECU packages before shipping.  The Hondata smanager software does include several basemaps for free that you can use as a starting point once you've registered the system.  For more advanced setups, or if you'd like us to create a custom basemap for you, we offer custom basemaps for use with the S300 system here: Hondata S300 custom basemap
