GM 3 Bar Map Sensor Adapter Harness – 08-Current Busa



This is intended for those ECU Flashing their Turbo Charged Gen 2 Busa (08-Current) using ECU Editor.  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).  You can purchase a GM 3 bar map sensor, and using this adapter harness plug it directly in place of the stock map sensor without hacking any wiring etc.  Now you have the ability to map your bike via boost pressure vs rpm, which eliminates the need for another set of injectors and a stand alone fuel controller.  My personal 08 turbo made 356 hp using stock injectors, 1:1 fuel regulator set at 42 psi, using the gm 3 bar map sensor mapping.  Once you have this, you can also use ECU boost control solenoid kit to have a different boost level in every gear.  A GM 3 bar map sensor can be picked up through, Jegs, Summit, etc.

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.
