Fuel Management Systems for Harley Davidson Buying Guide

Finding a fuel management system that suits your budget size and revamps your Harley Davidson with enhanced exhaust systems and other features to get your money’s worth. Check out the buying guide we have brought up for you to understand how to make the best pick.

Installation Difficulty Level

Broken down into easy, medium, or hard levels, the installation can be either very user-friendly, i.e., any customer will handle the installation using the common tools. 

A medium leveled system would be where users would make it work using a manual guide but would require specialized tools and mechanical skills.

Whereas the hard level is where a professional or very mechanically inclined user is required with a vague installation that demands the user to make few decisions on his own

Learning Capability

The fuel management system or auto tuner is best when learning and automatically making map adjustments while you ride. Whereas non-learning auto tuners make adjustments while you ride but don’t save or learn these adjustments for the next rides.

Mapping Dynamic

The fuel management system that comes with dynamic mapping can adjust the AFR (Air Fuel Ratio) target accordingly on the ride to offer optimal performance on the throttle and optimal fuel economy.

Wide Band O2 Sensors

Such sensors emit voltages of the varying range that can correlate to how far off the exhaust ratio target is the engine operating. Thus allowing the device to immediately narrow down the AFR (air to fuel ratio) target range for the optimal performance level.

Air Fuel Ratio Target (AFR)

Commonly referred to as A/F or the AFR Ratio is the exhaust ratio or the air to fuel ratio injected into the cylinders. The leaner (more air, less fuel) mixture is guaranteed by the higher numbers on the scale, whereas the lower, the richer (more fuel, less air) mixture is not economically feasible. The leaner mixtures improve fuel economy while the slightly richer mixture produces more power and cooler engine temperatures.

Timing Adjustment Capabilities

The ignition timing typically refers to when the ignition system delivers the spark plug’s signal to fire up. Usually, during the compression stroke, a few degrees before the piston moves to reach the TC (Top Dead Centre), The ignition timing is recorded in the degrees corresponding to the crankshaft ratio. 

Being able to adjust the timings is vital when making major modifications like STAGE II and above. For instance, if the ignition occurs after the piston has started traveling back down towards the cylinder, this would consequently cause a decrease in the air/fuel mixture pressure and offer weaker combustion, thus robbing the engine of power.

Conclusion

The above mentioned Fuel Management Systems are our top best picks for your Harley. Though they might lean on a pricey side a bit, we suggest you don’t skip them and instead save up as they are a MUST BUY, instead of going for the cheaper options that would be budget-friendly but would relegate your Harley’s performance.
