Harley-Davidson enthusiasts are always looking for ways to increase performance and customize their favorite ride. If you perform maintenance on your bike, you've probably heard of something called an ECM. The electronic control module (ECM) or engine control unit (ECU) is responsible for creating a well-balanced air-fuel ratio. The trouble is, these systems can wear out over time, resulting in a significant loss of power.
Harley fans choose to tweak stock ECM components in the hopes of creating the ultimate riding experience. At Fat Head Cycles, we specialize in aftermarket parts and accessories for Harley-Davidsons. We're here to help you decide if a repair or replacement job is in order for your original ECM unit.
An ECM acts like the brain of your engine compartment. This compact device works with sensors scattered across your motorcycle to influence engine behaviors for smooth functionality. Any time you modify your motorcycle's exhaust system or engine, it's crucial to ensure the ECM is responding correctly for fuel efficiency, power delivery and temperature regulation.
Think of a motorcycle's ECM almost like a computer. Out of the box, the technology arrives with presets that control user settings. However, there is room for modification to match riding preferences, similar to a system update.
Most riders will notice several warning signs that the ECM is malfunctioning. Note that there is a difference between an ECM unit that is out of order and one that does not meet your expectations. If you experience the following, your stock installation might be the culprit:
As mentioned previously, the ECM is like the brain of your Harley. Some riders want to make changes to the unit so that there are base map improvements, fewer RPM restrictions and zero errors after exhaust system changes. For your safety and that of your passengers, ECM repairs and troubleshooting should only be performed by a trained professional.
Keep in mind that altering or "tuning" your stock ECM is a complex process that involves overriding manufacturer settings. Attempting to do a repair or modification job yourself could lead to a seized engine if it's done incorrectly.

We are aware there are orders outstanding. Rest assured that your order has not been missed nor forgotten. Things here at Fat Head Cycles have changed drastically over the past few months and our small operation has had to adjust and adapt to maintain the accuracy and quality of our products. Our supply chains have been affected, distribution centers are backlogged and national shipping agencies have been severely affected by COVID19. Unfortunately, these things are completely out of our control.
The majority of orders containing Sony and Rockford products take between 21-28 BUSINESS days to custom assemble, ship and arrive at your doorstep. Once your order ships you will receive a SHIPPING CONFIRMATION email stating your order is on the way with tracking information. If you have not received this email your order is still in fulfillment que and is working its way up the list.
