Datalogging Cables
  • USB Versions
    • USB Kit
      • FTDI Chip Set & USB Drivers
      • COM Ports assigned by drivers
      • Depends on which USB port on your computer the cable is plugged into
    • Serial (RS232) Cable
      • No drivers or automatic COM port assignment
      • Requires 9 pin (DB9) serial port on computer
16
Chip Burner
  • BURN1 USB Chip Burner
    • Burns AT29C256, 27SF512, and AM29F040 chips
    • Reads 27C256 chips
    • Self powered from USB Connector
    • Comes with stand-alone chip programming software as well as built in support for burning BIN files within Crome Engine Management, eCtune & Hondata
17
Chip Emulator
  • Ostrich Eprom Emulator
    • Support within all major DIY Editors (Hondata, eCtune, Crome, Uberdata, TurboEdit & B.R.E.
    • Allows for real time tuning updates by ‘emulating’ an Eprom chip
    • Single USB connection to computer and 28 wire ribbon cable for connectivity to ECU
18
Standalone Tuning Boards
  • Hondata S300 (www.hondata.com)
    • Fits inside the ECU
    • Single USB Connection
    • On board logging memory
  • Neptune RTP (www.hrtuning.com)
    • Fits inside the ECU
    • Single USB connection or Bluetooth
    • Fits in a standard chipped ECU
19
Conversion Harness
  • Converts from one OBD (on board diagnostic) version to another.
  • Most popular conversions
    • OBD0 to OBD1
    • OBD2a to OBD1
    • OBD2b to OBD1
  • Tuning Harnesses (OBD1 to OBD1)
    • Use wire harness during tuning instead of splicing into customer harness.  Saves times & money.

Conversion Harness continued…
  • OBD0 to OBD1 Harness
    • 1988 to 1991 Honda CRX (Hf, Si or MPFI Converted)
    • 1988 to 1991 Honda Civic (Ex, Si or MPFI Converted)
    • 1990 to 1991 Acura Integra
  • No wires need to be added to stock wire harness, pigtail includes all extra wiring (VTEC, Knock, O2 Sensor
  • Rywire.com does DPFI to MPFI harness conversions
  • Use an OBD1 or OBD2 Distributor
21
Conversion Harness continued…
  • OBD2a to OBD1
    • Plug and Play for manual automobiles & OBD1 ECU
    • Retain OBD2 Distributor
    • Non-Vtec Civic uses a 3-wire IACV.  Converted to a 2-wire for better results using a Civic VTEC Intake Manifold (D16Y8) & IACV
  • 1996-1999 Acura Integra
  • 1996-1998 Honda Civic
  • 1996-2001 Honda Prelude
  • 1996-1997 Honda Accord

  • 1998-2002 Honda Accord
23
Wideband O2 Sensor
  • Wideband O2 Sensor is critical to tuning/troubleshooting any car
  • How WB Sensors Work
  • There are many cheap widebands on the market these days, features to look for:
    • Configurable analog outputs, for feeding to ECU dataloggers or for narrowband simulation
    • Proper calibration (for sensor life deterioration)
    • Low cost replacement parts
