The Sevice manual shows that the FI system has IAP sensors, TP sensors, CMP sensor, IAT sensor, ECT sensor not to mention the Vacum Damper that all intersect with the Air Box.
I am not planning to install this Big Black Box on my car and was wondering if anyone has had any experience with relocating, or otherwise rerouting this digital mess elsewhere under the bonnet.

The best place I have found for information on the busa is

Keep the air box - feed it with ram air, retain the 12bhp+ and additional torque you will otherwise lose.

If you get an aftermarket sausage filter the sensor can be mounted to the new plate and the diaphram hose is just bocked up.
