Title: What sensor turns on the secondary fuel injection on a turbo 2007 Busa
Post by: Busa2 on April 13, 2017, 04:03:13 PM

I have a 2007 Hayabusa with a Stage 2 Velocity Turbo.  Bike can cruise to 100 mph easy.  Full throttle under load starts breaking up at Approx 7000 RPM.  I've had the bike a while--didn't ride much last year due to health issue..  Installed a new tach light--broke a few 20 gauge wires in the process--re-soldered.  The turbo appears to be acting correctly--just seems like I'm hitting a fuel shortage.
What determines the secondary fuel turn on except for the ECU????
Thanks for your help.
Darrell

You should have a 3bar map sensor, that connects to your secondary computer and meters the fuel under boost..
