The term Auto Tune can be misleading, especially with several versions available for Dynojet’s Power Vision. Riders often wonder: which option works best? In this article, we break down Auto Tune Basic, Auto Tune Pro, and Target Tune so you can clearly understand the differences.
What is Auto Tune?
Auto Tune is a feature in Power Vision that helps refine your Harley’s fuel mapping. It uses O2 sensor feedback to generate tune corrections. These corrections optimize air-fuel ratios, improving both performance and ride quality.
However, not all Auto Tune versions function the same. That’s why it’s important to compare the three options before deciding.
Auto Tune Basic
Auto Tune Basic works with Harley models from 2007–2020. It requires no extra hardware, making it the easiest entry point. Using factory narrowband O2 sensors, it populates tune corrections directly into your base map.
Still, Auto Tune Basic has limits. Narrowband sensors can only read a narrow AFR range (14.3–15.2). Therefore, it’s most effective under light to moderate loads.
Auto Tune Pro
Auto Tune Pro offers more flexibility. It works on Harley models from 2001–2020 and requires the Auto Tune Pro accessory kit. This kit includes wideband sensors and a controller that connects to Power Vision.
Wideband sensors measure a much broader AFR range (10:1–18:1). They log data across throttle positions, RPMs, and even wide-open throttle. Unlike Auto Tune Basic, Pro works in open loop mode, storing AFR data for later corrections.
Many aftermarket exhausts already include 18mm bungs for wideband sensors. If not, you’ll need to modify your exhaust to fit them.
Target Tune
Target Tune takes things further. It also uses wideband sensors but integrates them directly with your Harley’s ECM. Once flashed with a Target Tune calibration, your bike can read wideband feedback in real time.
This means Target Tune works continuously in closed loop mode. It automatically adjusts fueling across the full operating range. Moreover, AFR targets remain fully customizable in WinPV.
Target Tune also includes an Auto Tune mode, similar to Basic and Pro. This allows you to create tune corrections and apply them directly to your base tune.
Choosing the Right Auto Tune
So, which option fits your bike?
Choose Auto Tune Basic if you want a free, simple solution using stock sensors.
Select Auto Tune Pro if you want wideband accuracy but prefer applying logged corrections afterward.
Go for Target Tune if you want real-time closed loop adjustments with maximum flexibility.
Understanding the differences between Power Vision Auto Tune Basic, Pro, and Target Tune helps you make an informed decision. Each option offers unique benefits depending on your riding style and setup.
