This is for intended for 08-Current Hayabusa ECU Flashing. This can also be used on 07-13 GSXR1000 if using a Hayabusa Bin File to flash. This is the greatest part of Gen II Hayabusa ECU flashing in my opinion (sorry gen I Busa guys this isn’t available for 02-07 bikes). Assuming you have a gm 3 bar map sensor on the bike, you can plug this solenoid kit directly into the PAIR valve output and control boost by gear. It works great, and only requires plugging the solenoid in, and tapping into a boost source, and running to the top side of your external gate. This can be used on an internal gate as well. The photo below shows a GM 3 bar map sensor adapter harness, which is not included, that must be purchased seperately at www.boostbysmith.com/3bar.html. Also please not the 1/8npt fittings and vacuum hose aren’t included, this is just the solenoid pre-wired to plug into the stock wiring harness.
