Product Description

A Hondata system consists of additional components which are added to the standard ECU to allow the ECU to use a Hondata program (this modification is normally done by the dealer). An interface box is then connected to the ECU which contains circuitry for datalogging, stores rev limits and interfaces to switches in the vehicle. Optionally a clutch switch, push button and datalogging cable may be installed. Collectively all this is known as a Hondata system.

The s300/s300j system has the following features:

Main features:

  • Fits inside the ECU
  • Made in USA
  • 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.
  • 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
  • Three multi purpose outputs for nitrous control or similar
  • Supports lambda tracing from a wideband o2 (PLX wideband recommended)
  • PWM output for boost control
  • Dual tables for high/low octane calibrations etc.
  • Two analog inputs for wideband, EGTs etc.

SManager editing software features:

  • High and low speed 24 × 20 ignition and fuel tables for correct VTEC tuning
  • Injector size fuel trim
  • Fuel trim for starting, throttle tip in and individual cylinder trim
  • Rev limiter with fuel cut or fuel and ignition cut
  • Launch control with anti-lag
  • Full throttle shift
  • Adjustable VTEC window with load and throttle control
  • Secondary intake runner control
  • Adjustable idle speed
  • MAP sensor type and calibration
  • Adjustable boost cut with hot and cold settings
  • Shift light
  • Closed loop control
  • Air temperature compensation
  • Water temperature compensation
  • Fuel and ignition correction based on gear
  • A/C shutoff conditions
  • Closed loop
  • Three general purpose outputs for nitrous control, quad boost control or similar
  • On board datalogging trigger conditions

The 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 s300. The s300 is made to fit in a full frame ECU case (US and most markets), so will not fit in a JDM ECU case.

The s100 system has the following features:

  • Fits inside the ECU. No external wiring.
  • Speed limiter removed (if applicable).
  • Tunable fuel and ignition tables.
  • Expanded fuel & ignition tables for boost.
  • Expanded rpm fuel & ignition tables.
  • A/C cutout.
  • VTEC control (non user adjustable).
  • Rev limiter (non user adjustable).
  • Nitrous Control.
