Cobra Fi2000R Fuel Tuner For Harley Rocker

The Fi2000R uses proven technology to give riders a simple, easy to install and adjust digital fuel-injection tuner. These units are preset by Cobra for your bike. You do not need to download a fuel-map from the Internet and upload that into your bike's ECU. This unit also has three adjustment pots that allow you to make adjustments simply and quickly if you choose to continue modifying your bike. For those of you who are a little overwhelmed by the recent 'map mania', the Fi2000R is just the ticket.

The Fi2000R enables the user to adjust fuel delivery in three parameters The first is a low-speed circuit, comparable to swapping a pilot jet on a carburetor. There are ten possible settings on the tuner; every two increments is roughly equivalent to a jump upwards of one jet size.  The second is a mid-range circuit, which is analogous to the needle and clip on a carb. An adjustment of one increment is roughly equivalent to a shim on a carb needle, and two increments can be thought of as dropping the clip one whole position. The final circuit, predictably, is the high-speed circuit, which adjusts the same area of the throttle position as a main jet on a carburetor. Each increment is equivalent to bumping up one size on a carb's main jet.

Being an open-loop system , the Fi2000R can be used on models with or without oxygen sensors, and greatly simplifies tuning. It also allows you to run an earlier exhaust without O2 sensors if you so desire, and your state, local and federal laws allow. If you're comfortable tuning a carb but uncertain about fuel injection tuning, the Fi2000R is really the best way to help bridge the gap between what you know and what you want to learn.

As a final benefit, the Cobra unit removes a lot of the tricky stuff associated with electronics.  No laptop computer is needed to use this tuner, and because it is a piggyback device, unhooking it and returning to stock is as simple as removing the in-line connectors and re-attaching your factory connectors.


  • Electrical leads have connectors to mate to your bike's stock injection system - no cutting, tapping, or splicing is needed
  • Open-loop design allows more exhaust options
  • An electronic equivalent to the 'jet kit' of yesteryear
  • Full range of fuel settings cover even fairly heavily modified bikes - the unit allows room for increasing your power output
  • Step-by-step instructions are included
  • Fantastic for smoothing the powerband, eliminating emissions-control-induced choppy low-speed throttle, and lean popping on deceleration
  • Corrects lean air/fuel mixture issues, helps cure lean-burn-induced heat, and helps eliminate hesitation on hard acceleration and surging while cruising
  • Waterproof circuit board
  • No fuel maps, downloads, or even a computer required

A shopper asked: My 2011 Rocker C has this Cobra installed on it, before it was lagging a bit and I bought a tuner for it, "DynoJet Power Vision", Stopped a lot of concerns. Now lately my bike has been acting strange, like not getting the fuel it needs for start up, acts as if the battery is dead or dying, keep the bike on the trickle charger now. While checking the battery this morning I found this Fi2000 tuner hidden in the battery storage. Does this tuner and the Power Vision tuner have a conflict. I always thought that my first gear start off from stop is just to slow, seem to me that the bike was not getting the fuel it needed. So I guess I need to know if the Cobra and Dyno can live together happily, and is there a way to check if the Cobra is still functioning properly? Nov 9, 2014

A S: So I did remove the Cobra from the bike. It started up the way it suppose to now. Guess I would have to say that the two can not be friends. If your reading this I hope it helps. Nov 9, 2014
