HA Motorsports Professionally socketed OBD1 VTEC ECU. This is our P28 equivalent ECU socketed for use with Hondata S300 systems ONLY (Fits S300 V1, V2, and V3).

Note: This ECU requires an S300 to be able to operate your vehicle and will not run without it.

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.
