Motorcycle Tuning Is What We Do.

Dyno Developed. Real-World Refined.

Our ECU development process goes far beyond simply putting a motorcycle on a dyno and chasing a peak horsepower number.

All 2WDW Custom ECU Mapping is developed in-house through extensive dyno testing, allowing us to precisely evaluate and optimize fueling, ignition timing, electronic throttle (ETV/STP) mapping, and other available ECU parameters under controlled and repeatable conditions.

But our development doesn't stop at the dyno. Our tuning is further tested and refined through real-world riding and extensive datalogging. This allows us to evaluate how the motorcycle responds with our custom ECU mapping across the wide range of loads, speeds, temperatures, atmospheric conditions, and transient situations encountered outside of the dyno room.

By combining controlled dyno development with real-world testing and datalog analysis, we're able to develop complete ECU calibrations for the stock and aftermarket intake/exhaust combinations we support—not simply a tune that produces a good dyno graph.

Over 250,000 Dyno Runs—and Counting.

Our development facility is equipped with two in-house dynamometers that allow us to perform the extensive testing required to develop, validate, and continually refine our custom ECU mapping.

After over 250,000 dyno runs, we've accumulated an enormous amount of experience testing motorcycles across a wide variety of manufacturers, engine configurations, modifications, and applications.

That unparalleled experience is one of the most important parts of what you're purchasing when you choose 2WDW. Our mapping isn't based on theory, generic files, or a handful of dyno runs. It's the product of years of continuous testing, development, datalogging, and refinement.

From ECU Development to MotoAmerica

The same approach we use to develop ECU mapping for our customers has also led to 2WDW becoming a tuning and technical partner for factory-backed teams competing in MotoAmerica.

Working at the professional racing level gives us the opportunity to apply our calibration, electronics, datalogging, and diagnostic experience in one of the most demanding environments in American motorcycle racing. It also continually challenges us to improve our processes, solve complex technical problems, and extract the maximum available performance from the motorcycles and electronic systems we're working with.

Our involvement in MotoAmerica isn't separate from what we do every day at 2WDW. It's an extension of it. The same emphasis on testing, data, repeatability, and continual refinement that drives our racing partnerships is fundamental to the way we develop our custom ECU mapping.

Mapping Developed for Your Motorcycle's Specific Setup

We don't believe that every motorcycle of a particular model should simply receive the same calibration.

Where applicable, we develop and maintain mapping for the different stock and aftermarket intake/exhaust combinations we support. That allows us to provide a calibration developed specifically around the configuration of your motorcycle rather than relying on a one-size-fits-all approach.

As we continue testing new configurations and learning more about the platforms we support, our mapping continues to evolve as well.

That's also why our Mail-In ECU Flashing Service includes free future mapping updates for as long as you own the motorcycle. If your setup changes and an updated map is needed, you can send your ECU back to us and pay only the cost of shipping it.

Local Dyno Tuning & Motorcycle Services

Although ECU development and our Mail-In ECU Flashing Service have become the primary focus of 2WDW, we haven't forgotten our roots.

We continue to offer in-house dyno tuning and selected motorcycle performance, maintenance, diagnostic, and repair services at our Washington facility. These services are now offered on a more limited basis as our development schedule and workload allow.

Our facility and dynos also remain an essential part of our ECU development program, allowing us to continually test new motorcycles, new aftermarket components, and new calibration strategies.

The 2WDW Difference

Motorcycles aren't simply something we work on—they're what we've built our business around.

Our team's experience comes from multiple decades of tuning engines, over 250,000 dyno runs, racing, developing tuning for the newest motorcycle platforms on the market, and providing tuning and technical support at the highest level of American motorcycle racing.

We're constantly working on the next platform, the next calibration, and the next refinement to the motorcycles we already support.

Whether your ECU arrives at our facility from across the country, your motorcycle rolls through our doors for development or dyno tuning, or we're supporting a race program at the track, the objective is the same:
