Hayabusa K2-K7 ECU Interfaces

• Two types– Gauge data only– Gauge data and programming interface

• Based on FTDI TTL232R 5.0V cable which supports the special baud rate for gauge data. Can be bought from (www.ftdichip.com)

• For programming interface an additional 4 connector switch is required

TxD pin 29

Optional LED with 220Ohm resistor can be connected between these Red/Black pins to indicate non programming state.

Programming and gauge data interface for K2-K7 Hayabusaby PetriK, 2008

Switch

This interface is based on using USB to RS232TTL converter using one ON-ON switch with 4 separate contacts.

The TxD,RxD, FWE and MD1 are connected to ECU harness connector to empty slots. The Gauge data and GND must be connected to wires that are already connected to ECU.
