The regular Air Fuel gauges tap into an existing narrow band O2 sensor. Since you dont have one, unless your a CA model, you would still have to drill and weld in a bung, then buy and install a narrow band o2 sensor. Not sure on any of the others, but Innovate uses Bosch heated wideband which is commonly used on VW and other production cars, so the sensor to replace only cost about $60, some are as high as $300, but the accuracy b/w them is nil. Narrow bands are only accurate at stoich, or 14.7:1 afr. Other than that the have a non-linear swing to the voltage so the "cute" little lights flashes from one end to the other rapidly A LOT and after a few minutes "cute" becomes "annoying." Your Busa should cruise and idle around 14.7:1 or again, stoich. So the lights would hover around the middle, green area. ANY throttle change will send those lights flashing one side or another, and back-n-forth. WOT you want your bikes AFR set IAW the build, use etc... e.g. a turbo Busa may want an AFR of 11.5:1, slightly richer than prime power, but the extra fuel keeps the cyl temps down and produces more torque...whereas if it were 12.5:1 (this is accepted afr that makes "peak" torque, it may blow a head gasket, melt a piston etc..
In theory, the follow AFR are prescribed
13.1:1 = peak hp (use for Naturally Aspirated, hp likes less fuel)
12.5:1 = peak tq (use for NA, tq likes more fuel)
You adjust from there and dial your combo in. You simply cannot do that with a narrow band O2 sensor, you can get it in the ball park, but the park can be big enough to allow too lean or rich, sacrificing the engine or power!
