08-Current Hayabusa Progressive Nitrous Harness



The Plug and Play Nitrous Harness to be controlled by your stock (reflashed with ECU Editor) ECU!

  • Fully plug and play (requires 1 wire splice if you don’t want to hold a button to spray)
  • Provides a Window Switch (Arm and Disarm RPM programmable in ECU Editor)
  • Provides a WOT switch (TPS > 95% programmable in ECU Editor)
  • Ability to adjust Nitrous Duty Cycle, Fuel Add, Ignition Retard, Ramp Up Time for every gear!
  • Adjustable ramp rates for NOS, FUEL, IGNITION as well
  • Riders who just want to spray a small shot without doing progressive can use the same harness!

    To use this on a GSXR1000 you must run a Hayabusa Bin File in the ECU. When doing this, you will lose the idle control solenoid control, and you must do some IAP remapping as the IAP sensor on GSXR1000 and Hayabusa aren’t the same.

    Two ways to turn Nitrous On, best of both worlds from 1 harness:

  • Option 1: Push and Hold Mode UP or DOWN Button Entire Time You Want To Spray / Window RPM / Wide Open Throttle
  • Option 2: Have Toggle Switch in the On Position (requires 1 wire splice near ECU connector) / Window RPM / Wide Open Throttle


Upgraded fuel pump is a good idea if spraying much more than 30 hp on a stock engine.


Please note that while I do my best to ship items the business day after they are ordered, I am not always able to do this.

If you have an urgent need for anything, please email me directly greg@boostbysmith.com.

Domestic:  I ship most packages USPS priority mail, which is advertised as 2-3 business days.
Smaller items with shipping rates at just a few bucks are sent USPS first class mail.
I can ship UPS ground as well.

International:  Due to long delays with USPS during Covid 19, I am only shipping via UPS.
The customer is responsible for any brokerage/customs fees.  My site is setup to add $55
for international shipments as this is the worst case for UPS with rare exception of a remote service
zone fee which I will contact you if this is the case.

In the event that shipping is less than $55 I will send a refund.  Feel free to contact me in advance and I can check exact shipping for you.
