Injection System
Gen 1
The 1st generation Hayabusa has 4x injectors. Listed as 330cc/min.
Gen 2
The 2nd generation Hayabusa has a total of 8x injectors. 4x primary and 4x secondary injectors that are staged. All are listed as 280cc/min flow rate.
Ignition Coils
The igniters are built into the OEM ECU. To use the original ignition Denso 2-pin coils a 4ch external igniter (such as a Haltech HPI4) is required.
Dwell Time is 1.5ms@14V

Idle Valve
The idle control system is a stepper motor type. This can be controlled by all 2-connector Elite ECU models.

| Black/Light Green | Stepper 1B | Stepper 2 |
| Purple/White | Stepper 2A | Stepper 3 |
| Green | Stepper 2B | Stepper 4 |
Sub-Throttle System
Both models come with a sub-throttle system common to most motorbikes. This incorporates a second set of throttle blades controlled via stepper motor located between the air filter and the cable operated throttle blades. A position sensor is used to allow closed loop feedback control, similar to a DBW system. This allows the ECU to override the riders input to reduce power under certain conditions.

Coolant Temperature
Wiring is not polarity sensitive
Calibration: Use "xxxxx.cal"
Created for Haltech ECUs using a 1k pullup to 5V
Air Temp
Wiring is not polarity sensitive.
Calibration: Use "Temperature - xxxxxx.cal"
Created for Haltech ECUs using a 1k pullup to 5V
O2 Sensor
A narrowband O2 Sensor comes standard on these models.
Vehicle Speed Sensor
Both generations of this vehicle have a vehicle speed sensor is of a Hall Effect type. The signal is wired to the dash, and the dash sends a serial signal back to the OEM ECU.
To obtain a speed signal for the Haltech ECU an SPI will need to be shared with the signal going to the dash.
Gear Position Sensor
Both generations of this vehicle incorporate a gear position sensor. This can be connected to a spare AVI.
OEM ECU Information
Gen 1
The Gen 1 ECU uses the same ECU connectors as the Haltech Elite 2-connector ECU range.
1998-2001 use a 16-bit ECU with an 8x crank trigger
2002-2007 use a 32-bit ECU with a 24-1 crank trigger
