S300 Plug-In Module

The Hondata S300 Version 3 is an advanced engine management solution that seamlessly integrates with factory OBD1 Honda Engine Computers for manual transmission vehicles, vastly expanding their capabilities. This US-assembled module offers a comprehensive suite of features, including support for forced induction, advanced datalogging, real-time programming, Bluetooth connectivity, and critical engine protection systems. The S300 utilizes SManager software for intuitive tuning and datalogging, providing users with access to expanded fuel and ignition tables that can handle high boost pressures and high RPMs. Key features of the S300 V3 include support for ethanol content sensors, Bluetooth technology for both laptop and mobile device connectivity, significantly faster datalogging speeds (2-4x), CAN output, and serial output for integration with aftermarket dashboards. It also offers 8 analog inputs and 1 digital input for datalogging, increased datalogging memory (up to 2 hours), non-battery memory backup, and on-board calibration storage. Connectivity is achieved via USB or Radio technology, and real-time updating of ECU parameters is possible without interrupting engine operation. Compatibility is limited to OBD1 Honda Engine Computers, including specific ECU part numbers such as P06, P28, P30, P72, P74, and P75. Within the USA, this product is legal only for racing vehicles and is not intended for use on public highways. An AFR wideband sensor wired to the S300 is required for tuning.
