Cobra Fi2000R O2 Fuel Tuner For Harley Sportster

Cobra offers this intermediate Fuel Tuner product that slots in between the Fi2000R and the Pow'rPro for the tuner who wants closed-loop performance without breaking the bank. The Fi2000R O2 Fuel Processor allows you to tune your bike like a carbureted model (In fact, it's a little easier than your average carb), but still retains use of the HD ECM's closed-loop capabilities. This system relies on the factory ECM's ability to adjust the air-fuel ratio in real time, but modifies the ECM's typically lean commands to the injectors, helping your bike run cooler and more powerfully. The Fi2000rO2 is set up from Cobra specificially for your bike, but offers adjustability beyond their factory settings for hard-to-tune or highly-modified motorcycles

The Fi2000r O2 blends the best of two worlds: it offers the ease of tuning a carburetor or open-loop FI system, but the monitoring and rapid adjustments of a closed-loop FI system. For the rider that wants the ease of analog adjustability but desires the quick response and custom map changes that the factory computer is capable of performing.


  • Electrical leads have connectors to mate to your bike's stock injection system - no cutting, tapping, or splicing is needed
  • An electronic equivalent to the 'jet kit' of yesteryear
  • Full range of fuel settings cover even heavily modified bikes - the unit allows room for increasing your power output
  • Step-by-step instructions are included
  • 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 confusing fuel map downloads required

Good value for the money
I recently installed this on my '07 XL883R (Roadster), and was pleasantly surprised by the performance increase. I had installed a K&N air filter for the stock air cleaner, and tweaked the stock muffler; this combination has given the bike a noticeable improvement. There is no throttle hesitation, and highway acceleration is clearly better. In fact, the throttle response was a bit scary at first.

Installation was simple, and the instructions were easy to follow. Setup couldn't have been easier; it took about thirty minutes total. The instructions say there is no need to remove the fuel tank, but since removal is simple anyway, I found it easier to get the tank out of the way completely. There were no complicated computer downloads and multiple road tests required.

There just a couple of minor concerns. First, the red and green color LEDs were installed in opposite positions from what was described in the instructions. Second, make sure the plastic case is installed well below the top of the battery; otherwise when the cover on the motorcycle is closed it will push against the plastic case and split it open (the two halves just need to be pushed back together). The case could be a bit more robust.

I highly recommend this product for those who are looking for a simple, efficient, and no-nonsense solution to basic performance improvement concerns. It is well worth the money. Well done Cobra!

My xl1200r currently has some of the problems the O2 fuel tuner states it can fix. I hesitate to upgrade the engine in my bike with exhaust, air cleaner, cam and head work since the bike has what seem like issues that should be fixed first. I would prefer a closed-door system with the capability to reprogram the elm and then be removed (it would really enlighten me if I could install a new 'factory setting' into this email and prove that this errant behavior isn't a factory design). What "tuner" do you think is most likely to handle my problems and upgrades?

There are two distinct points as the bike warms up when the engine cuts off for about half - a - second and no one knows what is causing it, and adds that they've never seen this before. The elm does not have a fault code stored because of the major hesitation, either.

My bike is a 2007.

BEST ANSWER: Since I have installed the Fi2000r I have noticed a considerable improvement with the issues I was having/ this tuner rightfully claims to elevate. The Fi2000r, however is not a "map download" type tuner and it only functions while physically installed on the motorcycle. I agree that upgrading anything before diagnosing any current problems could be problematic. If your set on getting a map tuner there are many options. Fuelpak looks like a good product.
