Now available with Bluetooth! This is our turn-key ECU package for those who'd like to tune their car with the Neptune RTP software using a P72 ECU. The P72 ECU has all of the same features as our P28 ECU, but with the addition of a knock sensor board and IAB functionality. This allows the P72 to control the secondary intake runners (IAB's) on Integra GSR and Prelude H22 style engines. The knock sensor circuitry can also be used to detect detonation and aid the tuner in setting up the tune to run safely and avoid ignition detonation/pinging. If you are wanting to use the electronic boost control features of the software to control turbocharger boost levels, please select to "add pwm boost" from the drop-down menu.

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)

PWM Boost Option:  The Neptune 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 Neptune 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 via the Neptune RTP software - complete control over fuel and ignition maps, rev limits, vtec engagement, idle parameters, wideband input support, and so much more!
  • Laptop datalogging and on-board datalogging support allows you to review engine operation for tuning yourself or use with our eTuning service.
  • Fully reconditioned HA Motorsports P72 ECU - ECU casing is glass-bead blasted to restore new condition, ECU lids are powder coated for long-lasting finish, and ECU circuit board is completely cleaned and updated with our high-quality socketing components.
  • Additional inputs can be configured within the software for use with wideband O2 sensors, nitrous controls, etc.
  • Can control boost levels on turbocharged engines directly through the software when used with either a 3 port boost control solenoid or 4 port boost solenoid (Requires PWM boost circuitry option)
  • The Neptune RTP software includes many engine basemap options so that you can setup your own basemap and begin use. * For heavily modified engines, or if you are not comfortable setting up your own basemap, please see our Neptune RTP Custom Basemaps
  • Bluetooth support when you select the bluetooth option.
