Product Description


Cobra Fi2000R Closed-Loop Fuel Controller

Nearly every Cruiser motorcycle can benefit with the installation of the Fi2000R. Better throttle response, no backfiring, and smoother cruising are just a few of the areas improved by the Fi2000. When your engine has the proper air/fuel ratio metered to it, it can perform to its potential, run cooler and be a much more satisfying ride. The Fi2000 comes preset for your specific model. It is also set for your bike equipped with an aftermarket exhaust system. This setting will enhance the performance of the entirely stock bike as well. If you add a high-flow air filter system, you can quickly adjust your particular model because each comes with detailed instructions for making fine tuning adjustments.

  • The Fi2000 increases horsepower and torque by optimizing stock lean air/fuel ratios (helps cool the engine temperature as well)
  • No confusing computer downloads to install
  • Pre-configured from the factory for your bike and model, but easy to adjust should your specific application need it
  • Closed-loop design works on exhausts systems equipped with an oxygen sensor
  • Easy to understand instructions included with each kit

Questions & Answers

  • Will this work on my 09 cross bones if i use cobra slip on strait shots and a cobra air cleaner?

    By: mike

    Yes, the Cobra Fi2000R will fit your 2009 Harley Softail Crossbones. Considering the configuration you have, it'll do nicely with getting the most out of those Cobra accessories. The included instructions also have a recommended starting point for tuning your bike for the air cleaner and exhaust you already have installed on your bike. In fact, those settings were tested on a Softail using a Cobra air cleaner and Cobra exhaust!

  • Will it work on 2016 street bob with air cleaner and thunderheader

    By: Jp

    So long as the Thunderheader you have retains the OEM oxygen sensors, then yes, you should have no problem fitting this system to your machine. It's designed to work with a vast range of configurations and includes three adjustment pots that are similar in function to adjusting a carburetor. The included instructions make it a rather simple affair to get things set up for your needs. Just plug it in, make the recommended adjustments and go for a ride to see how it feels. After that, if needed - make the required adjustments and go for another ride. Repeat as such until the engine performs the way you want.

  • Will this unit work with my 2014 fat bob with screaming eagle intake and pipes?

    By: Chris

    Yes, this Cobra Fi2000R can absolutely be run on the 2014 Dyna Fat Bob with a Screamin' Eagle intake and aftermarket pipes! The kit can be configured to run on just about any configuration that doesn't involve modifying the combustion chamber or going crazy with the cam profiles. The included instructions do a pretty good job of explaining how to set up the device to work for your specific needs, too. After installing the fuel tuner, there's little more to do than set the three rheostat dials to the suggested baseline, go for a ride and adjust accordingly. Usually, it only takes two or three quick rides that include stop-and-go, cruising at street then highway speeds and full-throttle acceleration to get it set up right.

  • i have a 2008 rocker Y pipes exhaust with O2 sensors and stock air breather will this cobra stop the backfiring and make the bike perfrom but still work well when i make more upgrades

    By: rob

    The Cobra Fi2000R for the Harley Softail Rocker will most likely help for your needs, but one thing you'll certainly want to consider before making any other changes is to be sure that the exhaust you're using doesn't have any air leaks in it. Often, but not always - leaky fittings can be the culprit here. Another area that's highly suspect on Harley-Davidson motorcycles is the air intake. Specifically, the rubber intake gasket can become brittle, especially if a lot of your riding consists of stop-and-go traffic or you live in a southern, hotter climate. The higher engine temperature tend to cook the intake gasket. Have a look at that for a good seal between the manifold and the air cleaner just to be absolutely certain all is well on the intake side.

    If, after a good once-over, you still find that your Harley Rocker is backfiring, then it's time to adjust fueling. Cobra's HD Rocker Fi2000R is an excellent tool for addressing this. And, given its simple user interface, you'll be able to set it up to work with your configuration easily. The same goes for future modifications, any changes there will also be easily accommodated via the simple user interface. Plus, the included instructions do an excellent job of explaining exactly how to get the device set up for your specific needs.

  • How well will this work with a 2015 HD Street glide special, with a Vance and Hines power dual header, with rinehart slip ons and a ss big sucker air cleaner??

    By: Das

    So long as you've retained the Street Glide oxygen sensors with the installation of those exhaust components, the fuel controller will serve your needs rather well. It simply compares throttle input against the ECU signals and the air/fuel ratio of the exhaust gases. With that data, it automatically adjusts fuel delivery while you ride in order to give you the best throttle response and engine power output.

  • I have this controller on a 2012 Fatboy can I put the same controller on a 2012 ultra limited with same motor

    By: Guest

    Unfortunately, no, while the FLSTF and the FLHTK Electra Glide Ultra Limited do share the same motors, Cobra calls for a different fuel controller to fit either bike. For this reason, you will not be able to use the same controller on both bikes.

    By: Staff

  • Will this work on a 2016 road king?

    By: Stev

    So long as you wish to continue using the oxygen sensors on your bike, then yes - this is absolutely the correct unit to work on your bike.

    Simply choose the 2016 FLHR Road Kit from our fit guide and we'll get the correct fuel controller on its way to you, fast.

    By: Staff

  • Do I need the fi controller for just nh slip on??

    By: Scott

    While it's not required, if you want to get the best possible engine performance to be had upon the installation of those mufflers, then yes - you'll want want to adjust fueling to suit. The Fi2000R is an excellent match for the NH slip-on mufflers.

    By: Staff

  • Will the fi 2000r fit my Electra glide ultra low??

    By: Scott D.

    At the moment, Cobra doesn't produce any fuel controllers to fit the FLHTKL. We do, however, have a Vance & Hines FP3 Fuelpak that will fit that machine. It's also quite a bit more simple to install. All you need is an Android or iOS smartphone with the requisite FP3 app, and you've got everything you need to adjust fueling on your bike for any exhaust and/or air cleaner combination.

    By: Staff

  • Will this work on a 2015 iron 883 with the baffles removed from stock pipes and an aftermarket intake?

    By: Kyle

    Yes, this unit would actually work pretty well for your particular needs. You'll have to do a little tweaking via the three adjustment knobs that are on the XL883N tuner, but it's nothing complicated at all. In fact, the included instructions do an excellent job of explaining how to set up the Sportster tuner for your particular needs.

    By: Staff

  • What are the advantages of running a closed loop over an open?

    By: Guest

    Basically, a closed-loop tuner provides a finer degree of tuning since it relies on the bike's OEM oxygen sensor(s) to provide real-time exhaust gas analysis. In this way, the fuel tuner can adjust mapping instantly in order to deliver the best possible engine power and throttle response as conditions change.

    Open-loop systems are to be used only if you have very specific fueling requirements, or, your machine is equipped with an exhaust that doesn't accept oxygen sensors. The open-loop kits allow you additional flexibility in selecting your exhaust.

  • I'm looking to straight pipe my 2014 Yamaha vstar 950 will this work to fix how off the fuel to air ratio will be?

    By: Woody

    So long as that straight pipe you're using has a provision for the oxygen sensors, then yes - this is the ideal unit to get your bike's fuel mapping correct. In the instance the pipes you're using do not have a provision for the oxygen sensor, then you'll want to choose the standard Fi2000R instead. The standard unit does not plug into the oxygen sensors, so you can omit them upon installing the V-Star 950 straight pipe exhaust and not have to worry about the V-Star's instruments showing some kind of error.

    No matter which Vstar 950 Yamaha Fi2000R you choose, the included instructions do an excellent job of explaining, not only how to install the device, but also how to adjust it to get the most out of your new exhaust arrangement. It's all there and, for such a capable device, it's rather easy to configure for your needs.
