The s300 is a plug in module to the factory Honda Engine Computer (ECU) which vastly expands the capabilities of the factory ECU. Forced induction, datalogging, real time updating of parameters, engine protection are but a few of the s300 features.

S300 Features:

• Fits inside the ECU
• Built on the proven s100/s200 code base
• USB connection for speed and compatibility
• SManager Windows based software for parameter & table editing, calibration uploading and datalogging.
• Real-time updating of ECU
• Built in calibrations for common engine combinations
• Built in datalogging to a laptop
• On board datalogging memory (2 MB memory, 20-60 minutes datalogging)
• Adjustment for different sized injectors, with overall fuel trim.
• Configurable for any MAP sensor (to at 5 Bar and above)
• TPS based table lookup for ITBs
• Engine protection from over boost and over temperature.
• Expanded fuel and ignition tables, both in rpm and load, to 60 lbs boost and 11,000 rpm (these are not the upper limits)
• Launch control with anti-lag
• Full throttle shift
• Two multi purpose outputs for nitrous control or similar
• Lambda tracing (with a wideband o2 sensor)
