S300V3 Plug-In Engine Management Module

The Hondata S300 Version 3 (S300V3) is a sophisticated plug-in module designed to significantly enhance the functionality of factory Honda Engine Computers (ECUs). This module installs directly inside the ECU, offering advanced capabilities such as forced induction management, real-time parameter updating, and engine protection features. Key features of the S300V3 include built-in Bluetooth compatibility for wireless programming and datalogging via the Hondata Mobile app on iOS and Android devices, as well as a high-speed USB connection for faster data transfer. It provides expanded fuel and ignition tables that can reach up to 60 lbs of boost and 11,000 RPM, and it supports various configurations like TPS-based table lookup for individual throttle bodies and dual tables for different octane calibrations. Installation of the S300V3 requires modification of the ECU, including different connecting pins and a slot for the USB connector. It is designed to fit full-frame ECU cases commonly found in US and most markets; it will not fit JDM square case ECUs, for which the Hondata S300J is required. Professional installation is strongly recommended due to the complexity and risk of damaging the ECU, especially if it has been previously modified. The module also includes features like launch control with anti-lag, full-throttle shifting, and multiple multi-purpose outputs for accessories such as nitrous control or boost control via PWM output.
