For Honda and Acura enthusiasts looking to maximize their engine’s performance, the Hondata S300 Obd2 engine management system stands out as a premier solution. Building upon the solid foundation of factory Honda OBD1 ECUs, the Hondata S300 system provides unparalleled tuning capability, transforming your vehicle from a daily driver to a track-ready machine. Whether you’re running simple bolt-on modifications or building a high-horsepower, purpose-built race car, the Hondata S300 offers the flexibility and control needed to optimize engine performance.
The Hondata S300 system is designed for seamless integration with your existing OBD1 Honda engine computer. This powerful system is compatible with a wide range of 92-95 Honda/Acura OBD1 ECUs, including popular models like the USDM Vtec ECUs (P28, P72, P61) and USDM Non-Vtec options (P75, PR4, P05, P06). For JDM Vtec ECUs (p30, p72, p08, p27, pr3, p91), the S300J variant ensures compatibility. Notably, for those with newer OBD2 or older OBD0 vehicles, the Hondata S300 can still be utilized with the help of readily available OBD jumper harnesses, bridging the gap between different OBD standards and unlocking advanced tuning capabilities regardless of your vehicle’s original configuration.
The latest Version 3 of the Hondata S300 introduces a suite of cutting-edge features, further enhancing its tuning prowess and user experience. Support for ethanol content sensors allows for precise tuning when running E85 fuel, catering to the growing demand for alternative fuels. Integrated Bluetooth connectivity enables wireless laptop programming and datalogging, along with convenient mobile datalogging options. Datalogging speeds have been significantly improved, now running 2-4 times faster than previous versions, capturing critical engine data with greater precision. Expanded connectivity through CAN outputs and a serial output for popular dashboards like AiM MXL and Racepak IQ3 (with the 230-vmefi-hond adapter) provides comprehensive data integration for advanced users and racing applications.
The core of the Hondata S300 lies in its extensive feature set designed to give tuners complete control over engine parameters. Eight analog inputs and one digital input facilitate comprehensive datalogging, capturing a wide array of sensor data. Enhanced security features offer protection against theft and unauthorized access. On-board datalogging memory provides up to 2 hours of recording capacity, utilizing reliable non-battery memory backup. On-board calibration storage eliminates the need for external chips, streamlining the tuning process. Connectivity is robust, with both USB and Bluetooth options ensuring fast and versatile communication. The included SManager Windows-based software provides an intuitive interface for parameter and table editing, calibration uploading, and in-depth datalogging analysis. Real-time updating of ECU parameters and tables allows for immediate tuning adjustments, while built-in calibrations for common engine combinations offer a starting point for many setups.
Further expanding its capabilities, the Hondata S300 boasts adjustable settings for various injector sizes and MAP sensors (supporting up to 5 Bar and beyond), catering to a wide range of engine modifications. TPS-based table lookup for ITBs, engine protection from overboost, and expanded fuel and ignition tables accommodating high boost levels and RPMs demonstrate its advanced tuning capabilities. Three multipurpose outputs for nitrous control and PWM output for boost control, along with dual tables for different calibrations and analog inputs for wideband O2 sensors and EGTs, provide flexibility for complex engine setups. High and low-speed fuel and ignition tables optimize VTEC tuning, while individual cylinder trim, rev limiter with fuel/ignition cut, launch control with anti-lag, and full throttle shift features further enhance performance and control. Adjustable VTEC window, secondary intake runner control, adjustable idle speed, boost cut, shift light, closed loop control, and various temperature compensations round out the comprehensive feature list, making the Hondata S300 OBD2 the ultimate engine management solution for serious Honda tuners.
