Fi2000R EFI Controller Closed Loop

Installed the controller no issues. Directions were clear and concise. Install was easy. Cleared up my popping on deceleration. Improved the acceleration of the bike nicely. Idle also improved.

Wish I had done it sooner, it's like a different bike

Overall, very good. Was surprised on how much of a difference it was. They should give video instructions on how to install it.

A must have when putting cobra exhaust on a Honda shadow. Makes my bike run so much better and it was very easy to set up with no extra programming needed

I was very skeptical about this tuner, but boy was I wrong! Installation was easy for me, instructions were clear and the suggested settings spot on for my 2005 HD Fatboy with Vance & Hines straight shots with an upgraded breather.

If you're not impressed with how your bike preforms and are interested in making your bike the way it should. This is the easiest and most cost effective way I've found.

My Honda VTX 1800 popped and cracked (backfired) even after the desmog mod so I did research and and found out about the Fi 2000 R. I was a little skeptical but bit the bullet anyway. I am so glad I did. No more popping or cracking, throttle response improved. It's like riding a new motorcycle. It was easy to install plug and play. Thanks Parts Giant

Super easy to install and adjust if needed.

A must do if you change exhaust or air cleaner and worth every penny. Easy to install.

My M8 Roadking was completely stock and ran good. But it was running very lean. I had to up grade the oil pump and figured it was the perfect time to install a cam, air filter exhaust and a tuner. The Fi 2000 R CL works great. As advertised. I was getting a mil light/O2 sensor high voltage which means rich fuel mix. This tuner is very adjustable and can be dialed in very similar to a carburetor. I like it a lot! Thanks for making a tuner that is easy to install, simple to adjust and and works at a very reasonably priced.

Must have if you do any air cleaner upgrade or exhaust headers. My 2019 street glide is modified cobra headers, neighbor hater slip ons, and air cleaner, along with this cobra fuel tuner. Amazing.

It works great with my exhaust.

Better fuel mileage and better bottom end pull. And with true duels she runs great.

Although I don't have it quite tuned in yet, The Fi2000 seems to be a dream come true for the guy who wants to add a few mods. I've had Harleys for years so Im used to tuning carbs but I picked up my first Fuel injected model recently. A box stock 2001 Ultra Classic. While I still ride my Wide Glide, thats set up for get up and go, the Ultra is a nice relaxing ride but TOO quiet with stock pipes. I picked up a used set of used Reinharts just to try as I just want to hear it, but not brake windows. Sound wise not bad. These are not straight through muffers so I thought I'd be able to get away without any other modifications.I was wrong. Popped in the exhaust between up shifts and on deceleration. I found the Fi2000 by accident searching for a Power Commander, or a FuelPac but both are pretty pricey since I'm not doing any real performance mods. I read the reviews on TheFi2000 and it all sounded good so thought FOR $250 give or take it was a inexpensive alternative. It was not a complete plug and play for me but the tech was more than helpful and even added some tips for tuning. Super easy install. Super super easy tuning adjustments. I told the tech what it was doing and he told me jut what I needed to adjust.Went for a ride yesterday in 95+n degree heat and the big ran great. Some very slight pops but I'm sure if I mess with it a little more I'll be able to tune that out too. My only tip would be to check the paper work and make sure its adjusted exactly as the paperwork suggests for your state of mods. A small adjustment can make a big difference.

Simple installation. Plug and play.

Ordered this for my vtx Honda 1800, installing it wasn't terribly difficult would have saved me some time if I could have known what injector went (both connectors were exactly the same, one connector was supposed to be brown) just had to reconnect them. Haven't had a chance to finalize the tune up but appears to be simple enough. Rain is interrupting things! Really nothing bad to say but just like everyone else the plastic casing could be a little better.

The Fi2000r has exceeded my expectation, this tuner has transformed my super 88 into a fun and exciting machine

This thing works great. I'm a factory trained harley mechanic. I bought a 2012 yamaha v star 1300 with only 725 miles off of ebay. Rode it and it felt like it was running warm and struggle a little on take off. Cut off on me one time on take off. Read about this online and it got great reviews. After installing....what a difference. Never worked on a v star and it was easy to install.

Good product. Terrible install directions.

Works great. Hook it up and let it do its thing. My bike runs much better now. Thank you

Easy install. What delayed the install was delaying reading the instructions

Controller 2 months in, works as it should. Throttle is much more responsive and smoother, on my 05 Road king with cable throttle.

Fairly easy to install had to make a few adjustments but so far so good.

Have a 06 Softail Standard w/Vance & Hines big radius pipes. Got rid of the backfiring on decel and made it more responsive. Easy to install, well worth the money.

Instructions were a bit difficult to understand, however I was able to get it installed. Seems to work as it should.

Eliminated all my backfiring on deceleration, really woke my bike up, will definitely use this tuner on future bikes. Well worth the investment. Only downside, the plastic case could be a little heavier. Overall great product.

Very simple to install, and on my first ride I could tell a difference, 2017 Harley road glide with a 107 M8. The idle was steady and smooth and I could feel the bike pull more than normal, nothing crazy but you could feel the difference. If you just want to do a intake and exhaust swap this is definitely the way to go for a decent price.

The fuel management system is everything I've expected and very pleased

Good direction working well with my 03 Harley and I will say it is great

Simple tuning for simple upgrades. Works as expected.

I have cobra tuners on all my Harley's and they are the fastest bikes around for each weight class. In fact my 1200 custom beat my husband Dyna that had a vance and Hines. But not now since I bought him a cobra! I switched to vance and Hines and was utterly shocked at the power loss, speed loss, throttle response loss.

Easy to assemble but I'm still tuning the device to improve performance

Great item! It was a little tricky to install because of my electronic ignition. All three light are suppose to come on and stay on when you turn the ignition on. With my bike they only stayed on for a few seconds. When I started the bike the green light stayed on, as it was suppose to. My bike backed fired when I came off the throttle in certain gears. This item corrected that problem. I like this item and highly recommend it.

Got my bike running right. Very happy. It was running lean before. Now it's just right.

Amazing performance right out of the gate! Immediately noticed a wonderful difference! Woke up my ol 88 something fierce! Combine with mass air and new exhaust, and wow... what a noticeable difference. Like a brand new bike and so much fun to ride now... love it! Only thing negative is it's cheap plastic. That's why I gave 4 stars on quality.

Bought a problem 1200 Sporty for the wife. It had been sitting for a while. After cleaning up the fuel system it had power but was just nasty stuttering at neutral throttle. Not knowing the history in the bike I bought this tuner because the price was right. As it turned out the bike is now pretty nice to ride. The idle is right, the acceleration is great and no more bucking and sputtering at neutral throttle.

Totally amazed at how easy it was to install and did amazing things for the bike, wished I would have known about it sooner.

Installed easily and improved air/fuel ratio which is why I bought it.

A little cheap on module material, but works well. Night and day difference didn't expect that much noticeable change. Had to bump yellow and red up one number to get good power difference, but very easy to adjust.

Made my bike a total different bike.

It made a night and day difference on my bike, but the actual tuner is made of cheap plastic.

Just installed the Fi200R along with a Big Sucker and Cobra speedster full exhaust on a 2005 Fatboy 88tc with 13000 mile. Amazing the difference this combo made. Bike runs and looks awesome. Worth every dollar.

Love it!

I am amazed at the difference this inexpensive tuner made. It's very easy to install and make adjustments.

Easy install, a true plug and play with no mapping, bike is running great but it's only been a few days so time will tell, I put a cobra timer on my 09 street glide in 2010 and it gave me 90,000 plus miles with no problem, traded that bike in for a 2022 in 2022 just installed this in March of 2024 so hopefully I'll write another review in 90,000 miles on my future bike. The quality of this seems a little cheap but the price is unbeatable.

Love it! Works great on my road king. Plug and play. Can really feel the difference!

I was shocked that the price was right, and I even more shocked with the results. I've had more expensive tuners, the Fi2000 was a fraction of the cost, and had a very noticeable improvement.

It's only March in upstate NY, so I haven't really tested it on the road. Install was simple. When I started it up with the new headers it tuned quickly.

Easy install, easy to adjust, and I was able to tell a significant difference in the ride as soon as it was on.

Easy installation.

Great product easy to install and tune the EFI. Well worth the money. 5 stars across the board.

Easy install and working great!

Made my 1999 FLHPI run a lot better.

Serious improvement.

If I could give 0 I would.

Works great. Helped a great deal with the low speed throttle. The shell of the tuner is made of very cheap plastic and will definitely break/crack easily. The instructions state once you turn power to the bike on the three lights will remain on until you crank it. Was not the case in my situation. The lights just blinked on so it made me think I did something wrong. Turned a 10 minute hook up to a lot of wasted time.

It is doing what it's supposed to be doing.

Does the job for me with a little adjusting.

Installed this on my Harley after changing my exhaust and air intake, works like a charm easy to install and no more popping on deceleration.

It only took me 1 hour to hook up. After jumping on my bike it was a big difference ... no popping ran much better best bang for your buck!

This thing did exactly what it said it would and was easily connected. Made a world of difference in how it runs. 2011 sportster 1200C. Would definitely recommend.

Worked like a charm.

This is great for my bike. I love it, overall performance is awesome. Great seller item shipped very quickly.

Very easy straightforward install. Installed on an 02 VTX 1800c that I just acquired with aftermarket pipes and intake. Prior to install had issues with deceleration popping and poor throttle response. After install bike runs and sounds 100% better than it did. I'm very happy with product. The only reason I might tinker with the factory settings would be to increase the MPG, but as I said it's a new bike for me so I haven't got that far yet.

Really woke my ultra up!

Easy to install

Easy install. Haven't fired it up yet.

Works well, instruction excellent!

I have a Honda fury that has An RPM limiter this product does not overcome that, I was under the impression it would. However It did solve several issues with new pipes and air cleaner very Necessary system without getting computer reflashed. I live in a rural area so having that type of a service done is not an easy task. Getting details and straight answers without learning the history of the world is not Possible yet. So I am grateful for Bolt on applications, I just would liked to have known if it would solve that specific issue but there is no way to find out for sure without spending the money and putting it on and then taking it off and putting another one on, welcome to 2024.

For as expensive as they are quality lacks in how it's made. Easy plug and play. It does what it says it does.

Really improved throttle response and installation was simple.

Put true dual Cobra headers on it with neighborhater slipon mufflers and the Fi 2000. I can hardly hang on now bike looks better sounds better and runs seriously better.

So far this tuner is doing what it's meant to do. I added big sucker air cleaner and exhaust on 04 dyna wideglide and after putting this tuner on. It doesn't have a high rev or popping like it did and love how it was preset and easy to install. Will buy again thank you

Is doing what it supposed to do. I am pleased with it.

Like it. Can tell the difference on the bike. Extremely easy install.

This fuel tuner has been the best mod I have added to my bike... it's amazing! It came preset up for my Honda Fury and the instructions made it easy to install, and adjust to my preferences. My bike runs like an ape!

Great quality

Changed air cleaner and slip ons on my Ultra Classic so added this fuel module. Bike seems to run a little cooler and definitely perform a lot better especially in first through fifth gears. Works really well with no deceleration popping. Nice upgrade would purchase it again. Had a few questions about the installation and the service techs responded right away as well.

After a brief conversation with one of their techs to determine which controller to order I was pleased to find out the less expensive controller was the one to buy that worked best for my situation. Installation was easy and I can't say enough positive about how it works. The bike runs like new, no stumbling or backfiring and steady @ idle. I can roll back on the throttle in any gear & the bike responds just the way it should without any hiccups. A great modification that fine tunes & coordinates the V&H header, its baffles & the Cobra air cleaner kit. A must for serious enthusiasts.

I knew the product prior to ordering another. You will see me again!

Good part, easy install, bike runs much better.

It really woke up my Softail after I installed the cobra exhaust. It's like a new bike, the performance is awesome.

All I can really say about this product is WOW! This is the second time that I have used the Fi2000 EFI Controller. The first time was on my 2012 Harley forty-eight. This time, it was a little easier installing it on to my son's 2014 Harley Sportster 1200 Custom. The directions are very straight forward. I connected everything as the directions described and let it idle for a little while. As soon as I took the motorcycle out on to the road, I could feel and tell the immediate difference than before. The motorcycle is my son's and so as soon as he rode it for the first time with the new Auto-Tuner, he was absolutely amazed at the difference. He was beyond happy. We had installed the Vance and Hines 2-into-2 Big Radius pipes and the Cobra PowerFlo Air Intake system onto his bike and the tuner did all the tuning we needed to make it run solid. I would definitely recommend this to anyone who doesn't want to go through the hassle of hooking up a computer to your tuner and dialing everything in. This was literally just plug and play. Great product!
