Why Invest in a Harley Davidson Tuner?

To understand why you should invest good tuners for your Harley, let’s talk about a few things:

  • The science behind tuners
  • the drawbacks of running lean
  • the benefits of an auto tuner

Got it? Get it? Good. Let’s keep moving – but I’ll break them down a bit first.

The Science Behind Tuners

A tuner is an electronic device designed to fine-tune your motorcycle’s performance. It does this by adjusting key parameters such as the air-to-fuel ratio and ignition timing based on your bike’s current setup. For instance, if you’ve upgraded your exhaust or air filter, your bike will require a different fuel mix and timing to reach its full potential.

The Drawbacks of Running Lean

Without a tuner, your Harley may end up running too lean, which means it’s not getting enough fuel for the amount of air it’s taking in. This can lead to engine damage over time, which is a costly and inconvenient fix. While some riders opt for a decel pop from their tune, it can also be a sign of running lean so keep an ear out for that.

The Benefits of an Auto Tuner

An auto tuner takes the guesswork out of optimizing your bike’s performance. It uses sensors to monitor your bike’s conditions and continuously adjusts the air-to-fuel ratio, ensuring that your motorcycle runs at its best at all times without having to manually adjust the bike’s factory settings – also known as the original map.

What to Consider When Buying a Harley Davidson Tuner

When looking for a tuner for your Harley, you should consider the following points:

  • compatability with your bike
  • tuner’s functionality and feautres
  • Ease of installation and use

Now, let’s break them down a little.

Compatibility with Your Bike

Before purchasing a tuner, ensure it’s compatible with your model and year.

Tuner Functionality and Features

Look for a tuner that offers the essential features for optimal tuning, such as air-to-fuel ratio adjustment, ignition timing control, and rev limit setting.

Ease of Installation and Use

A good tuner should be easy to install and use, with a user-friendly interface and clear instructions.

The Importance of a Professional Dyno Tune

While a good tuner can optimize your bike’s performance, nothing beats a professional level dyno tune. A professional tuner can put your bike through its paces under ideal conditions, ensuring that your bike is running at its very best.

However, it’s worth noting that your dyno gains will be affected by the other gear you’ve installed on the bike. I prefer matching the intake and exhausts depending on what stage the bike is tuned for. As an example, if my bike is tuned for stage 2, I’ll need an equivalent stage 2 air cleaner.
