The question is how can you manage this, when all the science is taking place inside the engine? Well, there is an answer and that is by getting an auto tuner. 

An auto tuner does the heavy work for you, assisting you to get the best out of your motorcycle at all times. Whether there are 20 calibrations available at the touch of a button or just 2 modes, the device will change the air to fuel ratio once the sensors note a change, ensuring maximum efficiency.

I have compiled a selection of the best auto tuners for Harley Davidsons and put all the information you need to know in this article, so let’s take a look.

  • Value For Money:★★★★☆
  • Ease of Install:★★★★★
  • Fit & Finish:★★★★★
  • Durability:★★★★☆
  • Features:★★★★★
  • Style:★★★★☆

The Vance and Hines Fuelpak 3 is the overriding best system for Harley Davidsons and it has a built in auto tuner. 

The stand out feature is the ability to access performance upgrades and mapping for exhaust systems that are available from the library of calibrations that have been developed by Vance and Hines.

The FP3 connects wirelessly via Bluetooth to any Android or IOS device. 

When the Fuelpak is plugged in, live information can be seen on your smartphone all through the Vance and Hines app, which is an easy interface to navigate. This is inclusive of but not limited to RPM, fuel economy, power, torque, cylinder head temperature, voltage, gear selection, speedo calibration.

The factory sensors are great for tuning with specific requirements such as special components or different quality fuel grades. The precision means your bike is getting the best possible air to fuel ratio at all times. 

It is an easy installation process with a clear instruction pack included and can be removed when live data or auto tuning isn’t needed.

The Dynojet Power Vision has been selected as the best tuner for the Harley 110 because it is a powerful system that can cope with all Harley engines including the huge powerful 1801cc engine. It is both a power tuner and data monitor.

It is built to easily tune any fuel injected Harley Davidson motorcycle, with the Delphi ECM.

The Power Vision has a full color touch screen unit, built in basic auto tune and is compatible via USB for tuning using a Windows PC.

A computer is not required to use the Power Vision unit which is really one of its best stand out features. All commands can be entered using the device’s touch screen. You can select your tune, download it to your bike and edit it all from the handlebar mounted unit. 

The device allows you to save up to 6 different tunes that can be flashed to the device in an instant and immediately change the air to fuel ratio to suit the riding conditions. 

Custom tunes can also be added to your unit, by being uploaded by a tuning shop or sent via email to be downloaded. 

The Power Vision comes with Auto Tune Basic which allows you to edit your tune to your saved calibrations, but Auto Tune Pro is available as an added extra sold separately. 

The display unit will show important information too as the bike is running such as RPM, MPG, trip mileage etc.

3. ThunderMax Tuner for Touring Models

  • Value For Money:★★★☆☆
  • Ease of Install:★★★★☆
  • Fit & Finish:★★★★★
  • Durability:★★★★★
  • Features:★★★★★
  • Style:★★★★☆

The ThunderMax Tuner is specifically manufactured for Harley Davidson Touring models and this generally therefore lends itself to being the best for the Harley 103 engine. Depending on your model year you will need to check it against the ThunderMax Tuner for specific compatibility with a particular version, but there are Tuners available for a wide range of model years. 

This tuner’s best selling point is the ease of installation. It comes 100% assembled with no need for wire splitting, you just simply need to replace the factory ECM and oxygen sensors.

Wideband oxygen sensors are constantly tracking the air to fuel ratio and feeding back to the ECM. Once you have inputted your preferred map, you don’t need to accept any changes as you ride, the ECM will control everything for you to your preferred requirements. 

The fueling adjustments react to very precise changes and that makes for a smoother running engine and absolute control.

ThunderMax tuning software offers a wide range of map configurations compatible with the ThunderMax tuner, or you can just upload a base map to work with too.

For California and other states where emission regulations are stricter, ThunderMax offers tuners that may be suitable for riding under these regulations.

It is worth noting that the MasterTune is not compatible with Apple/Mac.

Cables, and connectors will need to be ordered separately for your specific Harley Davidson model, but the MasterTune unit is suitable for the following Harley Davidson models and lends itself nicely to the relatively new Milwaukee Eight engine:

There is a Map Selection Switch available as an extra feature that allows the user to switch between 2 maps, so you can switch between fuel economy mode to full performance mode for example.

There is an abundance of features packed into the Power Commander including the ability to adjust the timing on individual cylinders. This is why it is the best tuner for the money.

Do You Need an Auto Tuner for Your Harley?

While you might not need an auto tuner for your Harley Davidson motorcycle, it is recommended. The correct air to fuel ratio is integral to a long lasting motorcycle. It is also particularly relevant for those owners who make modifications to their bikes.

It may be worth checking out this article about Harley Davidson performance exhausts, as an auto-tuner is considered a must, if you have upgraded your pipes. 

A quality exhaust upgrade can lead to extra horsepower being unleashed and your motor combusting fuel more efficiently. It is therefore, especially important to monitor your air to fuel ratio to ensure that this new performance lasts a long time.

If you are looking at performance enhancing mods for your motorcycle it is likely you will upgrade your air cleaner on your Harley too. We’ve covered some of the best air filters for Harley’s and they are well worth a look, as generally exhaust and air filter upgrades go hand in hand when making mods to improve your performance. 

This 2 minute video from Revzilla takes a quick look at why you need to retune after making these mods, and why it is a good idea even on a stock bike.

Right, now we know why you need an auto tuner. Let’s get straight into some reviews of 5 auto tunes for Harley Davidson motorcycles and then we will look at some of the other things you may need to consider.

The State Emission Laws

Emission laws vary from State to State, and is a very hot topic to consider at the moment. The impact emissions have on the environment is high up on debates in the U.S Government and Worldwide.

Harley Davidson had to pay a fine upwards of $12 million in a recent lawsuit to counteract the manufacturing and supply of ‘Super Tuners’ that violated U.S emission standards. 

This is an on-going issue and has resulted in the Sportster being dropped from the European Harley line up as it is not currently cost-effective for Harley to manufacture Sportsters that can pass the new Euro-5 emission laws.

When making any performance enhancing modifications to your Harley Davidson it is likely that emissions could be increased. An auto tuner will be able to help you get the most out of your motorcycle so it is the most efficient in its performance. 

What you need to be aware of, is your State’s laws in regards to this and whether your mods are keeping your emissions within the legal limits. 

The U.S Environmental Protection Agency is your best resource for all the information you need in regards to emission regulations. 

Wired or Wireless

Most auto tuners that are wired are mounted on the bike and come with controls and a display that will show you all the information you need. If it doesn’t have a live display it will plug into a computer to relay this information. 

Wireless auto tuners will connect via bluetooth to a smartphone or tablet device and that is where you will be able to access your information and controls. 

Neither option is necessarily better than the other, and it will really depends on what your preference is. If you think you will change your settings quite often and want to be able see all your information, bluetooth might be the way forward. If you just want one or two available settings at any time and to get on with the ride, a wired version may be best.

Harley Davdison Auto Tuner FAQ’S:

Last Checkpoint

When deciding which auto tune is best for you, consider the points mentioned in this article and you will be able to work out which features are going to best work for your needs. 

Be sure to check out your State’s emission laws and regulations in regards to your auto tune selection and make sure to check your motorcycle’s compatibility with the auto tuner you select. 

After that, enjoy having a motorcycle that will thank you for treating it with a piece of kit that will provide nothing but benefits while you’re out crunching road miles together.
