S300 V3 Engine Management System

The Hondata S300 Version 3 is a powerful engine management system that transforms a factory OBD1 Honda ECU into a fully reprogrammable unit. This allows for advanced tuning to optimize engine performance for various modifications, including forced induction setups. The S300 V3 is a plug-in module that significantly expands the capabilities of the original ECU. Key features include Bluetooth connectivity for wireless datalogging and tuning, along with support for iOS and Android mobile apps for on-the-go monitoring. It also integrates ethanol sensor support for flex-fuel tuning, with advanced protection inputs and flex-fuel ignition compensation. For data acquisition, it supports AIM and Racepak dash outputs, and includes Winqual certified USB drivers for reliable computer connection. This ECU package includes a HA Motorsports prepared OBD1 P28 VTEC spec ECU, a new serialized Hondata S300 Version 3 system, the Hondata SManager software, and a 6-foot USB cable. The ECU casings are restored to like-new condition, often with new clear plexiglass lids and stainless steel screws. Many engine basemaps are included with the SManager software to assist with initial setup. Please note that the Hondata S300/P28 ECU setup is not compatible with a 2005 Honda Accord. For that specific vehicle, the KTuner ECU package is recommended. Additionally, while the S300 Version 3 requires an internet connection for registration and activation, it is designed for use with Windows XP, Vista, 7, 8, or 10 operating systems.
