The Hondata 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.
Main Hondata 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)
Hondata S300 SManager editing software features:
High and low speed 24 × 20 ignition and fuel tables for correct VTEC tuning

Two general purpose outputs for nitrous control, BOOST CONTROL (SEE RELATED PRODUTS) or similar
On board datalogging trigger conditions The Hondata s300 uses different connecting pins in the ECU from the s100/s200, and also has a slot cut in the side for the USB connector, so the ECU must be modified for use with the Hondata s300.
This Hondata s300 is made to fit in a full frame OBD1 ECU case (US and most markets) not JDM
