Product Description


Cobra Fi2000R 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
  • Easy to understand instructions included with each kit

Installed this on my 2005 Road King Classic with stock air and RC Component pipes and what a difference. It idles better runs better with no popping when I roll off the throttle. Easy easy install. Came with great instructions and support from Parts Giant. You'll need more zip ties than what is provided. Happy rider here!!

Questions & Answers

  • How much more horsepower can I get with this? Would having a K&N air filter work with this system?

    By: Pep

    Cobra's Fi2000R fuel controller can handle just about any aftermarket accessory you can throw at it, with the exception of a supercharger or turbo. Unfortunately, Cobra does not publish power gains since the exact numbers vary based on the configuration of your machine (exhaust, air filer, fuel used &etc.).

    By: Staff

  • will this help fuel millage, im only getting 30 mpg at present

    By: flash

    You would actually be reducing fuel mileage with the installation of an Fi2000R, or pretty much any fuel controller, than when compared to stock. Cobra's kits are designed specifically to negate the lean running stock configuration. When I say lean, I mean that there's less fuel being delivered via fuel-injection than what is optimal for peak performance. All late-model mass-produced bikes come from the factory tuned leaner than ideal so as to pass emissions regulations. By adding an Fi2000R, you're going to make the bike run richer (that is, add more fuel than stock) in order to get more power and better overall engine performance out of the bike.

    Simple things outside of adjusting fueling may help improve mileage, such as running correct tire pressure and smoothing your throttle or brake inputs.

    By: Staff

  • Does this unit reset the ecu as timing etc.?

    my Harley 2001 electra glide ultra classic had a key program put in it Techn Research will the cobra delete this program and reset the ecm to the cobra settings, therfore changing the timing, idle, and power

    By: flash

    No, the unit installs between the ECM and the fuel injectors on your machine where it only modifies the signal between those components. It doesn't actually make any changes to the ECM nor will it delete the key program on your machine. It simply changes the signals between the bike's on-board parts so as to improve throttle response and engine output.

    By: Staff

  • What is the warranty?

    By: JV

    All Cobra fuel controllers are covered by a one year manufacturer's warranty.

    By: Staff

  • Clever device...?

    For this unit to read the stock sensors, what exactly does that mean? My 06 night train isnt equipped with O2 sensors therefor many tuners will not work on my model and year.

    Is this an issue with the cobra for my 06 fxstbi?

    By: Joe

    The Fi2000R plugs directly into the OEM wire harness and, in this way, it's able to read data as it moves between the ECU and other devices on the bike. It then intercepts that signal and adjusts it as required in order to produce the best possible throttle response and engine performance. Similar to the way you'd adjust a carburetor (low, mid, high jetting) - there are three adjustment pots on the unit itself which you use to set up the bike to deliver fuel as you need. It doesn't require an oxygen sensor in order to function properly.

    Each device comes pre-set from the factory for use with a slip-on and/or aftermarket air cleaner. If you find that those settings are not ideal for your needs, the included instructions do a pretty good job of explaining exactly what adjustments you'd want to make based upon the way the bike responds at various power settings.

    By: Staff

  • Is this controller self adjusting and do you have to program it? I have a 2015 Yamaha bolt r- spec

    By: Collin

    The Fi2000R comes from the factory pre-programmed to work with an aftermarket full exhaust system, but can easily be adjusted to work with just about any exhaust and intake configuration. The included instructions do an excellent job of explaining how to go about adjusting the device to work with your exact configuration.

    If you want something that's truly self-adjusting, check out the Cobra PowrPro Black fuel controller. With that device, it's a simple matter of plugging it in and then going for a ride. That's all. If you're really picky about throttle response, there's also an iOS or Android smartphone application that can be used to really fine tune fuel delivery with the PowrPro Black. And like the Fi2000R, the included instructions help you get the most out of your fuel tuning needs.

    By: Staff

  • I have a 99 Raod king Classic with a Power Comander 3. If since added true duel exhaust . Would the Cobra replace that or work with it?

    Would the Cobra replace it or work with it?

    By: Guest

    Really, there's no point in utilizing a PC3 and an Fi2000R at the same time as they both connect to and adjust the same circuits. In the case of the Road King Power Commander 3, there's a litany of maps available on the Power Commander website that you can download that'll put your bike within the ballpark as far as tuning goes. Of course, if you were to retain the PC3, in order to get the most possible power out of the engine, you'd want to visit a dyno shop and have that device professionally tuned.

    By: Staff

  • I have a 2010 Honda Shadow Phantom 750 with the stock exhaust cut behind the baffles and mufflers. Will this work for me

    By: Tyler

    You would be able to adjust this particular Honda Phantom tuner to work with your exact setup. The device comes configured from the factory to work with a full exhaust system, which may get you close to your tuning needs. From there, you can adjust the three rheostats on the Fi2000R in much the same way as you would adjust a carburetor. The included instructions do an excellent job of explaining how to go about adjusting fuel delivery to get the best possible throttle response and engine power output for your exact needs.

    By: Staff

  • Is this what I need if I am purchasing a cobra slip on exhaust for a 2014 Yamaha 950 tourer?

    By: Karla

    Yes, we highly recommend the installation of a Cobra fuel controller with the installation this, or any other Cobra exhaust or intake components we sell. You'll notice in the instructions that come with slip-on, they recommend the installation of this controller as well. Better yet, the device will be configured with to work with the Cobra exhaust right out of the box, too. And best of all, the included Fi2000R instructions do an excellent job of explaining exactly how to fine-tune the device to give you the best possible performance for your bike's exact tuning needs.

    By: Staff

  • Does the Cobra utilize factory O2 sensors or does it bypass it like the PCV?

    I have Kawasaki Voyager with Vance and Hines exhaust that does not have a hole for O2 sensor. Do I need to make one to use the sensor?

    By: Gregory

    There's no provision for connecting oxygen sensors to the Fi2000R, nor does the kit come with O2 sensors. Everything you need to put it on 2009-2013 model year Voyagers is included in the box and installation is rather simple. Maybe twenty minutes worth of work, if you were to take your time!

    By: Staff

  • What do you do with sensor leads

    Does plugs come with kit

    By: Guest

    Cobra's Fi2000R plugs directly into the OEM wire harness on every model we have it listed to fit. For some machines, you may need to use the included T-tap to complete the job, but there's never any splicing or soldering of wires required to complete the installation.

    By: Staff

  • I have a 2000 FLHTCI I want to put true dual exhaust on maybe a stage 1 air box will this work and maybe later on upgrade to ca 95 in kit

    By: Kevin

    Cobra's Fi2000R fuel controllers are designed to work with pretty much any exhaust and air cleaner combination out there. They'll also work with cam sets of a modest lift (509 or less), but once you start getting into big bore kits and head work, they simply don't have the adjustment range required to delivery enough fuel to the combustion chamber. So, for your stage 1 air box and the true dual exhaust - no problemo, but you will need something purpose-built to handle fuel delivery on that 95" kit.

    By: Staff

  • 2004 road king

    I have Vance & Hines Big Radius exhaust 509 cams Gear Drive will this unit work with my setup

    By: Webb

    Provided it's a fuel-injected FLHRI you're referring to, then yes - the Fi2000R should be suitable for your needs. The tuner can be used on pretty much any Harley model with aftermarket exhausts and/or intakes. It's also suitable for use on machines with cams up to .510 - so the 509 cam set on your bike shouldn't be a problem.

    By: Staff

  • I've a 2014 v star 1300. Is this a n open or closed loop system?.

    Additionally, which would be preferable, & why?

    By: Drogden

    This particular unit would be the open-loop version as it doesn't rely on the bike's O2 sensor in order to adjust fuel delivery. If you plan on running your bike without the O2 sensor, this is the proper unit to get. About the best situation in which to run an open-loop setup is if you have very specific fuel delivery needs, particularly at higher RPMs.

    If you're using an aftermarket exhaust that does include a provision for the exhaust sensor, and you wish to leave it on the bike, you will want to purchase the Cobra Fi2000R Closed-Loop Fuel Controller. The closed-loop option actually allows for better tunability since there is a feedback loop on the exhaust that helps the Fi2000R adjust fuel delivery accordingly.

    By: Staff

  • What's vthe difference between this and the closed loop programmer?

    By: Jamie

    Simply put, Cobra's Fi2000R Closed-Loop Fuel Controller is designed to work on machines in which you want to keep the oxygen sensor installed on the exhaust. If you're running an aftermarket exhaust that has no provision for such, then the standard Fi2000R will do the trick.

    By: Staff

  • I have a 2008 FI vulcan N 1500 classic.Is their room under the seat to house the Cobra Fi2000R

    By: jeff

    Yes, absolutely. You are to install the VN1500 Classic fuel tuner directly under the seat against the rear fender. There are some Velcro pads included in the kit to help secure the tuner into position. The included instructions also include a diagram to clearly show you how everything is to be laid out.

    By: Staff

  • I have a mustang seat on my bike. will the cobra Fi2000r fuel controller fit under this seat.

    By: jeff

    The only machine for which we've run into that problem was a Softail Custom, but the customer was able to find a different spot than what was recommended in the instructions to place the controller. Generally speaking, most aftermarket seats have a pan that's shaped as close as possible to the OEM seat in order to avoid difficulties such as this. In the instance that you run into space problem on account of the seat pan's shape, there's enough cable that allows you to route the tuner into a different location, such as behind a battery box cover or under the fuel tank.

    By: Staff

  • Well I asked you earlier about my Harley Davidson 1996 1340 CC fuel injected and you said I probably could get by without using this fuel controller but what could and would happen if I don't use it what's the pros and cons

    By: Guest

    In the event you decide to forego modifying fuel delivery on your bike when installing a new exhaust, you may notice a few things:

    First, poor throttle response. The bike may miss at cruising speed with no changes in throttle input. It'll feel like it stumbles at times when your hand is steady. It may happen a lot, or at the other hand - it might not happen at all. It's impossible to say what you'll notice upon installation of a new exhaust.

    Second, you won't get the most out of your exhaust modification. That is to say, since the engine now breathes better, you have an opportunity to add more fuel to the combustion chamber and get more power to the ground. While not as annoying as the first point mentioned herein, if you're not putting an exhaust on your bike to get more power out of the engine, then why bother? In order to reap maximum benefit out of any intake or exhaust modification, we highly recommend that fuel delivery be adjusted for those modifications.

    The Fi2000R from Cobra easily addresses both of these issues. You get a device that's simple to install, very easy to configure and - should you make other changes in the future, it can be configured to work with those as well.

    By: Staff

  • Adjust Idle?

    I'm on a 2010 Honda Fury VT1300CX with Cobra Sweeps and Cobra PowrFlo intake. I'd like to achieve that distinct slow loping idle. Does the Fi2000R allow the adjustment of lower idle speeds? If so, down to what RPM?

    By: JCB

    There's no idle control function available with any Fi2000 fuel controller. It's only designed to adjust fuel delivery.

    By: Staff

  • 2016 fury will it work with slk nova exhaust with no additional tuning?

    By: Guest

    The Honda Fury Cobra Fi2000R will work with your particular setup, and will certainly get you better fueling than the stock ECU. However, if you want to get the most out of the device, just follow the detailed tuning instructions that are included with the kit. That document will explain exactly how to adjust the three controller pots on the device to dial it in for the biggest power gain and the best possible throttle response. There's no computer required, either - just install, ride and make the recommended changes based upon what you feel while you're out on the test ride. It really is a simple device to setup for custom tuning needs.

    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.

  • 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.

  • 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.

  • 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 to adjust fueling to suit. The Fi2000R is an excellent match for the NH slip-on mufflers.

  • 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.

  • 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.

  • 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 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.

  • 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 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.

  • 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.

  • will this add enough fuel to stop my ping on hot days on a 2007 electra glide

    By: chad

    This controller is indeed going to add fuel to compensate for performance upgrades, such as exhaust and/or intake kit, but it's not really designed to prevent pinging. The pinging itself could be the result of poor quality fuel, fuel that's of a lower octane than recommended. While the Fi2000 may help, it's certainly not guaranteed to prevent it.

  • Will this work with a 2017 Honda Fury ABS with Baron Big Air intake and Vance and Hines slip on mufflers? And, how would this compare to the Dynojet Power Commander V?

    By: John

    Cobra's Fi2000R for the 2017 Honda Fury is an excellent match for your particular configuration. It's easy to install and set up - and you don't need to make a trip to the dyno to get it all set for your specific needs. The Power Commander V, on the other hand - will require, at the least - a download of a map from the Dynojet website that's close to your current configuration. Or, for the best results using the Fury PC-V, you'll need to take your bike to a competent tuno shop, preferably a Dynojet-approved tuning center, in order to have a custom map built for your exact needs. While the overall potential of the PC-V is greater in terms of power gains, the only way to do that is with the added cost of a tuner's time.

    The Fi2000R will get you pretty close to the best possible engine power output and throttle response and it'll do it all without having to visit a dyno. Plus, the included instructions do an excellent job of explaining exactly how to adjust the unit (there are only three adjustment pots on the device) based upon how the bike acts when you're out riding it. In terms of bang for the buck, you can't go wrong with the Fi2000R.

  • This says works with all exhaust with no adjustment what about air intakes?

    By: william

    Yes, it works with pretty much any configuration your bike is set up with, be it completely stock with an aftermarket air cleaner and/or a full exhaust system without baffles. The unit reads the stock sensor inputs at 60Hz and tunes fueling accordingly for the best possible power output, regardless of atmospheric conditions (altitude, humidity) or the type of fuel used. It's a pretty clever device. You may have to make some changes to one of the three dials on the unit itself, but the included instructions explain under what conditions those dials are to be changed, and what direction to go. It's really simple device to use!

    About the only time the Fi2000R doesn't perform is on completely stock machines. Even at its lowest settings, it applies too much fuel for the stock intake and exhaust to handle and often, the bike runs poorly because of it. This situation only applies on bikes with a completely stock setup!

    By: Staff

  • Can this be used without having an aftermarket exhaust and intake put on? I'm planning on buying all three eventually.

    2013 vn900 classic

    By: Coru

    For the Vulcan 900, it's not a good idea as we've had more than one customer complain that the device actually made the bike run worse when it's the only aftermarket part used. Even at its lowest settings, it still adds too much fuel for the stock exhaust and stock intake setup. Your best bet would be to, at the very least, also add an exhaust or intake to the bike before purchasing the fuel tuner.

  • i have a 2003 ultra classic fuel-injected. i recently dumped the stock crossover pipes for cobra true duels and full bore mufflers with a two and a half inch bore. now the bike bogs rolling into first gear, stutters and pops around 2300 rpm and the power is down. ive been told she smells like shes dumping fuel under acceleration. will the cobra fi2000 cure any or all of these problems?

    By: wayne b

    If your bike wasn't tuned at all for the exhaust components you've just put on your bike, then yes - you definitely need a tune! The stock ECU just doesn't have a good enough map to compensate for those modifications. The bogging you notice is giant red flag for a lean-running engine. So long as your bike was running well enough before you added the exhaust system, then the Fi2000R, proper configured of course - will almost certainly mitigate these problems. It comes out-of-the-box setup to deal with a full exhaust system. And, after some seat time with the device plugged in, you should be able to zero in on the adjustments you need to make (there are only three knobs on the device) in order to get a well-running bike. And by well-running, we mean great throttle response and better engine power output than stock.

  • 2017 Honda vt1300cx Fury

    I have a Honda 2017 vt1300cx Fury. I have ordered Cobra swept pipes and a Cobra air Cleaner Assembly. Is it recommended I get this fuel controller? or the closed loop controller? Or do I need ANYTHING after install of pipes and new air cleaner? Thanks :))


    By: Greg

    Yes, this tuner would be perfect to fit your needs. We can't say enough good things about these controllers, they're simple to install and easy to configure. They come straight out of the box setup to deliver fuel for a full exhaust system, though, you may need to make some minor changes in order to get the most out of it with the Cobra air cleaner. The included instructions provide a really good explanation on what changes to make (there are only three rheostats on the tuner) in order to get the best possible throttle response and engine power output. The Fi2000R we have on offer is indeed of the closed-loop variety, which is the best option for your configuration since the Cobra headers come with a provision for fitting the OEM Honda oxygen sensor on your bike.

  • Will this fit my 2015 raider s, have stock air and barons nastyboy slashcuts

    By: Guest

    If you were to choose the 2015 Yamaha XV1900CS Raider S fuel tuner from our fit guide, you'd get the appropriate unit to fit your machine. With your Yamaha Raider exhaust system, this kit would be up to the task. Plus, should you decide to upgrade the intake system, a simple adjustment would be all that's needed to get the most out of that upgrade as well. This particular kit is a rather versatile fuel tuner for the Yamaha Raider.
