Dynojet Power Vision 4 for 2014–2020 Harley-Davidson Touring

The Dynojet Power Vision 4 PV4-15-02 gives compatible 2014–2020 Harley-Davidson Touring riders a simple, modern way to flash and manage ECU calibrations using a smartphone. Designed for compatible Harley-Davidson CAN Bus applications, Power Vision 4 combines Dynojet's proven tuning platform with Bluetooth connectivity and the Power Vision mobile app.

Whether you're running a stock motorcycle, slip-on mufflers, a high-flow intake, a complete exhaust system or a more involved performance combination, the correct ECU calibration helps the engine operate as intended with the parts installed.

Not sure which Power Vision fits your Harley? Fitment is determined by the motorcycle's ECU/application, not simply engine size. Contact Dreaded Iron Moto with your year and model before ordering if you're unsure.

PV4 vs. PV3: What's the Difference?

Both platforms are designed around Dynojet's Power Vision tuning ecosystem, but the rider experience is different.

Power Vision 4 uses Bluetooth and your compatible smartphone as the primary interface, making it a strong choice for riders who want a compact tuning device without permanently mounting a separate display.

Power Vision 3 uses its own dedicated color display and controls, making it the better choice for riders who prefer a standalone tuning and monitoring device.

Neither choice is automatically better for every rider. The right Power Vision depends on your motorcycle, modifications and how you want to interact with the tuning system.

When Should You Tune Your Harley?

A completely stock motorcycle or a bike with only slip-on mufflers may not require the same tuning changes as a motorcycle with multiple airflow or engine modifications.

Once you're combining upgrades such as a high-flow intake, aftermarket headers, complete exhaust system or performance camshaft, proper calibration becomes increasingly important. More extensive engine combinations may benefit from professional or custom tuning rather than relying solely on a preconfigured calibration.

Built for Riders Who Want a Complete Performance Setup

At Dreaded Iron Moto, we look at the motorcycle as a complete combination. Exhaust, intake, engine modifications and tuning should work together rather than being selected as unrelated parts.

If you're building a Harley Touring performance package and aren't sure which Power Vision or tuning setup makes sense, send us your year, model and current modifications. We'll help point you in the right direction before you order.
