RSR Air Shift Module w/autoshift – Plug and Play KillBox


Does the horn still need to be able to beep with RSR turned off?


BoostBySmith offers this completely hassle free, plug and play RSR air shift module harness for your Gen 1 or Gen 2 ZX-14 as wel as Gen1/Gen2 Busa.

Some details on the awesome killbox itself.

Engine Kill Times are adjustable per gear shift. This is great for those with 1-2 or 1-2-3 Auto Transmissions, or those who may need to adjust kill time for added power down track. Adjustable Solenoid Advance Time allows the solenoid to apply pressure to the shift linkage before the engine kill sequence begins to allow faster shifts with less delay. Auto Shifting built right into the controller with no need for added boxes or chips. Can be wired to ground or +12v shift buttons for manual shifting. Works on any motorsports engine with a digital ignition (Not CDI) 1, 2, 3, or 4 Cylinders.


Adjustable Shift Count (Number of shifts)
Adjustable Kill Time Per Gear Shift 0-150ms in 1ms Increments
Adjustable Solenoid Advance Time 10-40ms in 1ms Increments
Adjustable Auto Shift RPM 2000-16,000 RPM in 10 RPM Increments Per Gear
Adjustable Shift Input Polarity (Ground or +12v)

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

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.
