Our tools optimize horsepower, efficiency, and safety, matching aftermarket upgrades. Founded by racing experts, we empower tuners and enthusiasts. About OEFI Tuning
In the fast-paced world of powersports, where every ounce of performance counts, engines have evolved into sophisticated marvels of engineering. Today's powersports engines are equipped with advanced programming that goes far beyond t

he capabilities of traditional ECU tuners. Yet, unlocking their full potential has often been a challenge—until now. This is why OEFI Tuning was created: to empower racers, enthusiasts, and performance shops with the tools they need to fine-tune their rides for maximum horsepower, efficiency, and reliability. At OEFI Tuning, we specialize in cutting-edge software and hardware solutions designed specifically for ECU (Engine Control Unit) and ECM (Engine Control Module) calibration. Whether you're upgrading with aftermarket exhausts, intakes, turbo kits, or other performance enhancements, our products bridge the gap between stock settings and optimized performance. Traditional tuning methods fall short because they can't fully adapt to these modifications, leaving valuable gains in power, fuel economy, and safety features untapped. Our innovative approach changes that by providing precise, user-friendly tools that allow for custom calibrations tailored to your exact setup. Our Story
OEFI Tuning is a dynamic spinoff born from a passion for powersports innovation and a recognition of the industry's unmet needs. Founded by a team of experienced engineers and racing professionals, we saw firsthand how outdated tuning options were holding back riders from achieving peak performance. Drawing on years of expertise in automotive electronics and performance optimization, we developed a suite of hardware and software that puts control back in your hands. From drag strips to off-road trails, our mission is simple: to make advanced ECU tuning accessible, effective, and safe for everyone—from weekend warriors to professional tuners. What Sets Us Apart

Precision Engineering: Our hardware interfaces seamlessly with a wide range of powersports vehicles, including ATVs, UTVs and snowmobiles. Combined with intuitive software, you can adjust parameters like fuel mapping, ignition timing, throttle response, and more—all in real-time. Our calibrations ensure your added performance products work in harmony with the ECU, delivering measurable increases in torque, speed, and efficiency without compromising engine longevity. Safety First: We prioritize built-in safeguards, such as real-time monitoring for overheating, knock detection, and emissions compliance, helping you push limits responsibly. User-Friendly Design: No need for a PhD in engineering. Our tools feature easy-to-navigate interfaces, detailed tutorials, and support resources, making them ideal for performance shops looking to offer premium services or individual racers tuning from their garage. Why Choose OEFI Tuning? In an era where powersports technology advances rapidly, staying ahead means having the right tools. We've helped countless users transform their vehicles from stock performers into track-dominating machines, all while improving fuel efficiency and reducing wear.

We are out validating and making sure our mapping changes are doing what they should. We are testing a few things.

1. 2017 AC 800 HO with Stage 2 kit running solely on ECU tune. No piggyback fuel controller. We have eliminated the AC high elevation bog when hot and it is a blast to ride.

2. 2026 Pol Boost - We are testing a 26 plus 20hp pump gas tune to make sure our latest definitions are spot on. This sled is a blast to ride, if you see us out in the back country come say hi and we will have you throw a leg over it and try it for yourself.

3. 2024 AC 800 CTEC - testing a few baseline 0310 calibration fixes. Been good so far.

We are in West Yellowstone if you see us make sure to say hi.

We are out in West Yellowstone trying a few things . If you are out come find us and say hi 🏁
