Best Auto Tuner for Harley Davidson in 2022

When it comes to making the best of your bike, an air-fuel ratio is one of the key parameters to play with. It impacts performance as well as the life of your motor, and everything in between.

A motorcycle straight out of the factory is designed to deliver nearly-perfect power. Nearly is precisely the word because of legal restrictions. Hiccups might emerge over time, too.

Top 5 Best Harley Tuners

5 Best Harley Davidson Auto Tuners

Here is our own top pick plus four great alternatives in case you want something different.

1. Vance & Hines Fuelpak FP3 – Best Tuner for Harley M8 114

Fuelpak FP3 boasts a combination of powerful fuel management and engine diagnostic toolkit with wireless connectivity, making it easy to use with an Android/iOS smartphone. The 6-pin HD-LAN CAN Bus system is used to establish a connection with your bike. FP3 then relies on harmless Bluetooth to send the necessary data to your mobile device, which you can access via the specialized Vance & Hines application.

With this app, readings such as your current speed, RPMs, selected gear, cylinder head temperature, and more are presented on the screen. It enables you to calibrate your speedometer and gives you trouble codes if needed.

Flash technology is used for assessment and calibration. In particular, it can adjust your ECM for optimum performance, while the autotune feature adds precision and accuracy. The device keeps track of what is happening to your exhaust system by creating a custom map. Besides, there is a well-supported ready-made map library available, and your original manufacturer setting will be backed up in case you want to reverse the changes you make.

The model is compatible with Harley Davidson FLH, FLT 2014-2020, FXD 2012-2017, FXST, FLST 2011-2017 XG500, XG750 2014-2020, XG750A 2017-2020, and XL 2014-2020. Like many auto tuner models, it doesn’t ship to California due to legal restrictions.

FAQ

What does the Fuelpak FP3 do?

The Fuelpak FP3 connects to iPhone or Android smartphones wirelessly via Bluetooth. It uses Flash technology to recalibrate engine parameters and mapping for exhaust systems and other performance upgrades downloaded from Vance & Hines’ expansive calibration library.

Will a FP3 work for a big bore kit?

The FuelPak FP3 tuner cannot be used with aftermarket cams or big bore kits.

Can I adjust idle with FP3?

The FP3 allows you to adjust critical engine parameters right from your smartphone, such as the rev limit, idle RPM, spark advance, and target Air Fuel Ratio. If you’re an experienced user, you’ll have full access to all ECU tables.

Can the Fuelpak be used on multiple bikes?

Using a Fuelpak FP3 to flash a bike permanently links the FP3 to that bike’s ECM. The FP3 can still be used with other bikes to read/clear codes and view live sensor data, but not to flash a different bike.

2. Vance & Hines Fuelpak FP3 66005 – The Best Fuel Management System for Harley Davidson

Another high-tech device made by Vance & Hines that will fit 2014-2019 Electra Glides, Road Kings and Street Glides, 2014-‘1019 Trikes; 2011-2019 Softails (except 2011-2013 CVO models), 2012-2017 Dynas, 2014-2019 Sportsters, and 2014-2019 Streets.

This model is very similar to our top pick in that it utilizes the same Bluetooth technology for effortless data transfer. The sleek minimalist design is also similar, and you can use your phone to monitor such vital information as speed, RPM, how hot the cylinder heads have got, gear selection, and more. Flash tuning is used to recalibrate the engine according to any modifications and downloaded maps.

Speaking about maps, the library is impressive, and quality support is provided by Vance & Hines technicians.

This model mainly differs from the generic FP3 in terms of compatibility and thus deserves to share the pedestal with it.

FAQ

How often should you change Harley fuel filter?

After you’re done looking over your motorcycle, it’s time to switch out the filters on Harley-Davidson®. This would entail the oil filter, air filter, and fuel filter. Generally, it’s advised that you complete this task every twelve months or 20,000 miles.

Which is better FP3 or FP4?

The Vance & Hines FP4 unit is smaller and has a longer wiring harness than the previous model, FuelPak FP3. This allows for more options when it comes to where the hardware can be located on the motorcycle. The unit also has simplified LEDs that show the communication between the unit and the bike.

How do I update FP3?

To calibrate your speedometer, simply connect your FP3 to your bike, select the desired MPH/KMH range, and hit the “calibrate” button. The updated settings will be automatically downloaded to your bike.

3. Dynojet Power Commander V – A Powerful Harley Tuner Kit

Compatible with Harley Davidson FXD DYNA MODELS, Dynojet Power Commander is another much-talked-about auto tuner that offers a lot of fuel efficiency and performance tuning options.

Just like the FP3 tuner reviewed above, this model uses a specialized application to help you navigate through fuel management tasks. While also easy to use and install, it doesn’t have the wireless connectivity feature, though. Instead, it uses a USB On-the-Go cable to connect to your phone, replacing which can be a bit of a pain. The device can also connect to your computer.

Apart from the autotune, launch control is accessible with Power Commander V. It also features an analog input that can be used to host a 0-5 sensor for more control based on boost or temperature through adjustment tables.

The model allows you to map each of your cylinders individually. Paired with gear-specific mapping, this provides for a vast number of truly granular combinations.

If you upgrade some parts of your bike after installing Dynojet Power Commander, you can still find the right tunes because the ready-made settings library is huge. Finally, the unit is easy to install just in case you want your stock settings back.

The device comes in a sleek, compact, and durable casing that’s easy to install. Please mind that it is not legal to use in the state of California.

FAQ

What does a Dynojet Power Commander V do?

The Power Commander plugs into the bike’s stock ECU in order to make changes to the fuel and ignition curves. These changes are made via the Power Commander’s onboard microprocessor.

Does Power Commander V use O2 sensors?

The set includes two oxygen sensors, a control module with two inputs for sensors, a cable to connect to the CAN bus, a plug to terminate the CAN connection, and two custom cables for the sensors. It also has a connector for the bike’s stock wiring harness, so it can be easily connected to the power supply.

Does Power Commander V adjust timing?

The Ignition Module changes the timing in each individual cylinder for better performance.

Can a Power Commander hurt a motorcycle?

You could set the Power Commander to make the motorcycle run too lean, but it is not likely.

4. Dynojet Black Power Vision Tuner PV-2B – A Luxury Harley Auto Tuner

Another powerful fine-tuning tool for your Harley made by Dynojet, Black Power Vision PV-2B, will fit all CN ECM models, which means a vast majority of those made from 2011/2012 to 2020.

Just like the above device, this model uses a specialized application to help you pick and choose the necessary adjustments. It is not wireless; however, this is partly made up of a luxury feature — a high-contrast 3.5-inch color touch screen that’s easy to read on the go.

That is, you hardly need a phone at all when using Dynojet’s Black Power Vision. Instead, you can rely on the device itself as a live adjustment panel. It can also serve as a diagnostic tool due to the ability to create customized alarms. Those who want to store or manipulate their data extensively can connect to a PC when back in the garage.

Power Vision tuner review often mentions how intuitive and easy to adjust it is. Making your very own tune is very quick with it, and there is a whole library of pre-made ones. Installation is also easy because it uses standard mounting accessories.

While definitely not what you could call a budget-friendly option, this auto tuner is also built to last. Its unfussy design is shock-resistant and doesn’t mind rainy weather.
Note that you cannot use this auto-tuner in California.

5. ThunderMax Auto-Tune – Top Fuel Tuner for Harley Davidson Bikes

ThunderMax Auto Tune stands out immediately because it was made specifically to meet the needs of EFI-equipped Harley riders. The device targets 2017 – 2020 Harley Touring Motorcycle models. It also supports high-performance camshafts and will work in nitrous and supercharger settings.

Installation is fairly easy, although the manufacturer warns you that you might need to introduce minor changes to your O2 sensor port bungs. Unfortunately, the model is not cell phone friendly, meaning you can only connect it to your computer using a USB cable and the specialized software that comes with it. The software provides live diagnostics and examinations.

The closed-loop wideband sensor system that this device relies on provides for continuous adjustment on the go. There are hundreds of maps to choose from, and the fact that the front and rear cylinders are treated separately makes the adjustments even more granular. Apart from AFR maps, ignition and startup maps are available. Idle speed and rev limit can be adjusted, too. The device also provides speedometer calibration.

Another way in which ThunderMax clearly differs from the above models is its premium price. Luckily, it is partly made up for by a longer-than-usual limiter warranty of three years.

Buyer’s Guide: How to Choose the Best Harley Tuner

What an auto tuner does for your motorcycle is facilitate the adjustment of the air-fuel ratio where fuel injection technology is used. The ratio has a direct impact on the power and performance of your engine and can bring a lot of joy to your ride when tuned properly.

First of all, you need to make sure the model you are considering will fit your bike model by checking the specifications.

The next thing to take into account is how easy it is to install. Complicated procedures mean more time off your Harley and the potential for mistakes.

Oxygen sensors are an important part of any auto tuner. These fall into two categories, the less accurate narrow-band ones and wide-band sensors that enable the tuner to reach its target AFR in an efficient manner. This means that models that come with wide-band sensors generally perform better.

Spark plug timing adjustment is another important capability if you are planning a major update. Harley’s generic power commander normally doesn’t have this feature, but it is a welcome bonus.

Harley Davidson tuners come in both wired and wireless varieties. Wired tuners connect directly to the bike’s sensors and ECU, providing a more stable connection but being more difficult to install on motorcycles that are not easy to access. Wireless tuners are less expensive and easier to install but tend to work best on bikes that do not put out a lot of power.

Some tuners work with all Harley models, while others are only compatible with specific models. You need to make sure that the tuner you want to buy is compatible with your motorcycle. If you’re not sure, ask the manufacturer or an authorized dealer.

If you live in a state that has emission laws requiring an annual inspection, it is advisable to choose a tuner that gives you more options and adjustability. However, if your bike is registered in California or another state with such laws, you should use a tuner that meets those standards.

Finally, you should look for intuitive interfaces with maximum connectivity. A good library of pre-made Harley-friendly maps is also desirable as it can save you a lot of time.

Note: The use of aftermarket parts is restricted in California. You cannot use a tuner on highways unless it has been exempted. EPA is also concerned about tuners due to increased pollutant emissions.

Best Harley Davidson Tuner: FAQ

Here are the answers to some common questions that appear under Harley’s tuner reviews.

Do I Need a Tuner for My Harley?

You do if you want to increase the amount of air that inflows into your engine or simply want to increase your horsepower.

Should I Tune My Harley After Exhaust Replacement?

As a rule, you should. If you replace the exhaust and the air cleaner, an auto-tuner is a must.

What Does a Tuner Do for a Harley?

By providing for dynamic adjustment in AFT, an auto-tuner improves performance and power, also reducing the need for maintenance and servicing and improving the rider’s comfort with less chugging and stalling.

What Is the Best Year of Harley Davidson?

This depends on the model. For example, when it comes to Dyna Wide Glide, the 2008 version is said to be the absolute best.

Closing Remarks

While there are quite a number of decent Harley-Davidson tuner options on the market, few can offer ease of installation and effortless connectivity while remaining more or less budget-friendly.

We recommend Vance & Hines Fuelpak FP3 as it brings together modern wireless technology and excellent potential for engine control, making it ideal for a wide audience of riders.

Whether you want to follow our advice or prefer more specialized options, the accurate auto tuner will put an end to compromised power and annoying hiccups.
