How to Choose the Autotuner for Harley Davidson
An auto tuner helps you to keep your Harley Davidson running more efficiently and on the road longer. There are a few things that should be considered when you are buying an auto tuner. Some of these considerations are:
The Harley Model the Tuner is compatible with
Harley Davidson has made a lot of bikes, and each of their models are slightly different. Before you can purchase an auto tuner you must make sure that the tuner is designed to work with the Harley model that you have.
Most auto tuners will have the bike models and years that they are compatible with printed on the packaging.
The State Emission Laws
Unfortunately some state emissions laws will not allow you to use some auto tuners on your bike. Check your state emission laws before you make an auto tuner purchase so you can stay in compliance with the guidelines established in your state and county.
Wired or Wireless?
You have to decide if you would rather have an auto tuner that has a display screen or if you would like the information to be sent through Bluetooth technology to your smart phone. With a display screen you can usually mount the screen on to your handlebars and easily read the screen while you are traveling. The smartphone readings may be harder to access while you are rolling.
Unit Size and Connectivity
The size of the auto tuner may play a part in your decision. You have to look at how the unit connects to the bike, and where the unit will be on the bike to determine if the unit size will be good for your needs.
Adjustments
The final thing that you will consider is what adjustment choices you have in the tuning selections the device has. Most professionals prefer the customized settings where you get to make the decisions on the adjustments rather than just the reset to factory calibrations.
Final Note
An auto tuner is a precision piece of equipment that enhances the fuel management for your motorcycle. An auto tuner can make calculations and adjustments to the fuel your bike is consuming according to what grade of fuel you are using, and according to what you prefer.
Having this equipment could increase the life expectancy of your bike, and it could save you a lot of money on fuel consumption. Choose the style of tuner, and the features of the tuner carefully according to the make and model of bike that you ride.
