Unlock the full power of your machine. FAST-UTV ECU Tuning recalibrates your vehicle’s Engine Control Unit to match your exact setup, fuel type, and performance goals. Whether you’re running a stock UTV or a fully-built turbo system, proper ECU tuning transforms how your machine accelerates, responds, and performs in real-world riding conditions.

Your ECU controls crucial parameters including ignition timing, air-fuel ratios, boost pressure, torque limits, and throttle mapping. When these values are optimized for your build, the result is smoother power delivery, stronger mid-range torque, improved throttle response, and increased overall horsepower — all without sacrificing reliability.

Every FAST-UTV ECU tune begins with a full diagnostic review so we can understand how your machine is currently performing. We then create a custom calibration tailored to your modifications, whether you’re running aftermarket injectors, performance clutching, upgraded intakes, exhaust systems, or E85 ethanol blends. Nothing is copy-and-paste. Every tune is built from scratch for your UTV.

Once the calibration is complete, we verify it using our Mainline ProHub dyno. Multiple controlled pulls allow us to measure horsepower, torque, AFR ratios, and boost response under load. This ensures every adjustment delivers measurable and repeatable gains. Our team reviews the data with you so you understand what was improved and why it matters.

FAST-UTV offers ECU tuning for trail riders, desert racers, mud builds, and high-horsepower turbo applications. We support leading tuning platforms including HP Tuners, ECUtek, MoTeC, Haltech, Holley EFI, Link ECU, ProEFI, UpRev, and more. Whether you're seeking maximum power, safer fueling, or refined drivability, our tuning process delivers the results your build deserves.
