How Should I Choose The Reliable Auto Tuner For Harley Davidson?

Before you decide on buying an auto tuner, it is really important to look into the features of the product and how much you are going to spend on it.

The first thing you want to look into is compatibility because you want to make sure it is the right fit for your Harley model. Also, look for the state emission laws, the fuel consumption adjustments, whether it is wired or wireless, as well as the tuning parts, and lastly, the warranty.

All of these factors will help make your decision easier, and it is also important to test it so you do not end up with a defective product as it can risk the performance of your motorcycle.

Can I Change The Wires On Auto Tuners?

If you are planning on changing the wires for a wired auto tuner, then yea, you can change the wires. Make sure to check the instruction manual first so you can have a better idea about it.

Follow the instructions that are provided or consult an expert to get it done professionally. If your auto tuner does not have any information about changing the wires, then it is best not to mess around with it as that can impact the tuning done.

Why Should I Get An Auto Tuner For My Harley Bike?

The main reason why you would need an auto-tuner is so you can change the performance of your motorcycle exhaust, filters, and mufflers. An auto tuner will also ensure to provide an accurate amount of fuel inside the tank at all times.

Therefore, tuning is recommended and very much needed to increase the torque power as well as for high speed so you can have a smooth ride on your bike every time. But if you wish to ride how the motorcycle is manufactured originally, then you do not need tuning at all.

Do Auto Tuners Void Harley Davidson Bikes?

No, installing an auto-tuner on your Harley Davidson does not void the warranty at all. But if you are using stage four kit, it will most certainly void Harley’s warranty.

In addition to that, an aftermarket exhaust or electronic fuel injection (EFI) tuner can also affect the Harley Davidson warranty. Make sure to get it serviced at a dealership to protect your motorcycle. Also, you need to wait until your motorcycle warranty expires before you make any customization on it.
