This is our turn-key ECU package for those wanting to use the Hondata S300V3 with OBD1 P72 Integra GSR ECU to tune their car. Includes a specially prepared HA Motorsports OBD1 P72 ECU with full IAB control and knock board for applications with an intake manifold that requires IAB's (ie: GSR, H22, etc). The Hondata S300 system is fully installed into the ECU and completely tested for trouble-free operation.

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.


  • Allows complete engine control and tuning - complete tunability of fuel maps, ignition maps, vtec engagement, two-step rev limit, and so much more!
  • P72 ECU includes knock sensor circuitry to allow further tuning and ability to counter-act detonation/pinging.
  • P72 ECU includes IAB circuit to allow controlling the secondary intake runners on Integra GSR intake manifolds as well as H22, etc.
  • Additional inputs and outputs so the tuning platform can be customized to your engine setup (ie: nitrous control, etc).
  • PWM Boost control can be added to allow boost control directly through the software. Please simply select "ADD PWM BOOST" from the drop-down menu.
