Dynojet Research: Decades of Powersports Fuel Tuning Innovation

Dynojet Research has been at the forefront of powersports performance since its founding in the early 1970s. Born from a passion for motorcycles and racing, the company set out to solve a simple but critical problem: getting more power and smoother performance out of stock engines without sacrificing reliability. What started as a focused effort to improve carburetor fueling has grown into a comprehensive lineup of fuel management, EFI tuning, and performance upgrade products trusted by riders and tuners around the world.

Dynojet's reputation was built on one foundational product — the Jet Kit. Designed for carbureted motorcycles, Dynojet Jet Kits addressed the lean factory fuel calibrations that robbed bikes of power and throttle response. By recalibrating the needle, needle jet, and main jet, these kits unlocked smoother power delivery across the entire RPM range. They became the go-to solution for riders looking to wake up their carbureted machines, and they remain a staple for vintage and classic bike enthusiasts today.

When fuel injection began replacing carburetors, Dynojet adapted quickly. The Power Commander — now in its sixth generation — became the gold standard for inline EFI tuning. Dynojet's EFI Programmers intercept signals between the throttle body and ECU, allowing riders and tuners to remap fuel delivery across thousands of individual data points. Whether you're adding an aftermarket exhaust, upgrading an air intake, or simply trying to eliminate the flat spot at mid-throttle, a Power Commander gives you the precision control to dial in a perfect map. The later Power Vision series took this even further by flashing tunes directly to the ECU rather than operating as a piggyback device.

For riders who want straightforward fuel management without deep tuning complexity, Dynojet's Fuel Control Computers offer a plug-and-play solution. These compact units come preloaded with maps for specific vehicle configurations and allow on-the-fly adjustments — no laptop required. It's an ideal entry point for powersports enthusiasts who want real performance gains without a steep learning curve.

As the UTV and side-by-side market exploded, Dynojet expanded its product lineup to match. Their Turbocharger Electronic Boost Controllers — including the Boost Commander — give turbocharged UTV owners precise management over boost pressure, enabling safe and substantial power increases from forced-induction setups. Complementing this performance ecosystem, Dynojet's Multi Purpose Gauge Mounts and display accessories keep critical engine data — including air/fuel ratio readouts from their wideband O2 kits — front and center for the rider or driver.

What sets Dynojet apart is the breadth of the ecosystem. Their products are engineered to work together: a Power Commander paired with an Autotune wideband kit creates a self-optimizing fuel management system that learns your engine in real time. Few brands can claim both the heritage of founding an entire product category and the ongoing engineering investment to remain its benchmark decades later. Whether you ride a carbureted cruiser, a modern sport bike, or a turbocharged UTV, Dynojet Research has a tuning solution built for your machine.
