Yamaha XVS950 Midnight Star Cobra Fi2000R

Cobra FI and Powrpro differences i personall prefer the adjustability my YOU  of the Fi2000R over the more expensive powrpro where they decide !

With the Fi2000 PowrPro tuner installed on your bike, you have your own personal built-in dyno that analyzes your bike's performance, and constantly tunes the air/fuel ratio for ideal EFI delivery and optimum performance. And with the speed of today's microprocessors, it tunes on every squirt of the injectors. It provides perfect fuel settings in any riding conditions, with any exhaust system and with any engine modifications. And it's plug-in performance; just hook it up to your bike and immediately enjoy improved power beginning with the first time you twist the throttle.

Cobra Power Flo air filter to match your new power adder!!

No dyno testing to determine the right map. No confusing computer-mapping downloads to select and install.

No welding hassles with O2 sensors or costly pipe changes.

PowrPro will always supply optimum fuel ratios wherever you find yourself riding tomorrow, next month or next year.

It's like having the best custom map-writing software and a dyno operator tuning your fuel delivery 80 times a second, every time you crank open the throttle.

Tunes the acceleration fuel delivery in every gear, with every roll on, every environmental change, and every engine mod, whether you're lugging the engine or winding it out to redline: PowrPro reacts, verifies and adjusts instantaneously to current riding conditions.

No matter what kind of new hardware you install on your bike--a new exhaust system, a freer-flowing air filter setup or even a big-bore hop-up kit with high-performance cams--PowrPro continues to analyze and tune your engine for peak performance.

CVT - Continuously Variable Tuning. That's the key to the remarkable performance the Fi2000 PowrPro delivers. PowrPro uses electronic control technology that calculates the bike's rate of acceleration by reading crankshaft rotation at the flywheel and changes in load just as a dynamometer measures acceleration at the rear wheel. That allows PowrPro to measure and adjust fuel flow during acceleration to the injectors in microseconds for super-fast fuel tuning: continuously and automatically! Net result: precise EFI tuning now happens in the real world in real time, nonstop: at up to 80 times per second. And that's not just at peak power settings; whenever you open the throttle for acceleration, PowrPro delivers ideal fuel metering continuously, all through the power band, and under all loads for full power and the ultimate in smooth and crisp throttle response.
