4. Cobra Fi2000R PowrPro Tuner (Auto-Tune) for Harley Davidson 2010-11 Softail CVO
Since we know that carburetors are purely mechanical and fuel injection systems are computerized so, one may ask why can’t an injection system tune itself rather than having to be ‘mapped’? The engineers at Cobra Engineering raised this question and also came up with an answer to this: The Fi2000R PowrPro.
Cobra Fi2000R is innovative and is intended to work perfectly without reconfiguration or adjustment by the user. This automatically and continuously adjusts the mixture of the fuel when one is riding the bike. One does not need to download maps or a laptop and know trial and error ordeals.
This autotuner is available for all 2001-2012 fuel injected Harley Davidson motorcycles as well as for many, numerous, wide-ranged injected metric cruisers. The cobra Fi2000R achieves magical results simply by comparing fuel injector pulse width with rates of engine acceleration.
Then, regardless of the load, the RPM, the speed at which you are riding the bike, or other riding conditions- the Powr Pro constantly adjusts the pulse as required to improve the acceleration of your bike.
This device takes comparison samples and begins to react to them up to 80 times a second, as far as the rider is concerned, these adjustments are instantaneous. This is known as CVT (Continuously Variable Tuning). It is also to be noted that, unlike other EFI tuning devices, the Cobra Fi2000R Powr Pro does not retain any fueling information. The Powr Pro is active when the engine is running but does not retain any memory.
Cons
- Expensive
- The Powr Pro is active why the engine is running but has no memory (unlike other EFI tuning devices)
