S300 v3 ECU Programmer

The Hondata S300 v3 is a sophisticated plug-in module designed to significantly enhance the capabilities of your factory Honda Engine Computer (ECU). It transforms your stock ECU by enabling advanced features like forced induction management, comprehensive data logging, real-time parameter adjustments, and crucial engine protection systems. The v3 version connects via high-speed USB for both calibration programming and data logging, eliminating the need for separate serial connectors. It also boasts Bluetooth connectivity for wireless programming and mobile data logging. Key features of the S300 v3 include support for any linear MAP sensor, real-time updates that can be made with the engine running without interruption, and onboard flash memory for up to 2-hours of datalogging without a laptop. It offers 8 analog inputs and 1 digital input, primarily for data-logging purposes. The v3 model further adds ethanol content sensor support and CAN output, along with serial output for integration with popular dashboards like the AiM MXL and Racepak IQ3. Installation requires modification of the ECU, including cutting a slot for the USB connector, and it is strongly recommended that this process be performed by a professional. The S300 v3 is designed for vehicles with manual transmissions only and is compatible with typical rectangular body type USDM OBD1 ECUs such as P06, PR4, P28, P30, P61, P72, P74, and P75. Note that P06, PR4, P74, and P75 ECUs will require a VTEC conversion for VTEC functionality. The ECU itself is not included with the module.
