S300 V3 P28 ECU Package

The Hondata S300 V3 ECU package is a complete, turn-key engine management solution designed for tuning your vehicle. It features an HA Motorsports-prepared OBD1 P28 VTEC spec ECU with a new, serialized Hondata S300 Version 3 system professionally installed and tested. HA Motorsports ensures quality by producing these ECUs entirely in-house, socketing and modifying the circuit boards with quality components, and installing a full set of new capacitors for long-term reliability. The ECU casings are restored to a like-new condition using a glass bead blasting process, and are fitted with new clear plexiglass lids and stainless steel screws. This package includes the Hondata Smanager software, a 6-foot USB cable, and a one-year VIP warranty with full product support. For those seeking advanced control, the optional PWM Boost feature can be added to manage turbocharger boost pressure through an electronic boost control solenoid, enabling boost-by-gear functionality. Users will need a laptop running Windows XP, Vista, 7, 8, or 10 with an available USB port and an internet connection for system registration. Bluetooth connectivity is also included, allowing for wireless datalogging and tuning from a laptop or displaying engine information on iOS or Android devices via the Hondata Mobile App. Please note: The S300/P28 ECU setup is not compatible with a 2005 Honda Accord. For that vehicle, a KTuner ECU package is recommended. Additionally, the S300 unit is designed to fit in full-frame ECU cases (USDM/NZDM) and will not fit in JDM ECU cases. If using this ECU with a 1998 Honda Accord EX 2.3 VTEC with a manual transmission, an OBD2B to OBD1 harness is required, and the 3-wire IACV must be changed to a 2-wire configuration.
