DYNOJET Auto Tune Kit - Harley-Davidson AT-131

Precise fuel mapping is the difference between a bike that idles smooth on the highway and one that leaves power on the table. The DYNOJET Auto Tune Kit gives you real-time control over air/fuel ratios at every RPM and throttle position, letting you optimize for fuel economy during cruise or maximum power at full throttle. If you're running a Power Vision tuner, this kit transforms it from a simple reflash tool into a dynamic, closed-loop fuel management system.

The included oxygen sensors feed live AFR data back to your Power Vision display, enabling semi-automated fuel corrections without guesswork. Base calibrations are pre-loaded, but everything is fully adjustable—meaning you can dial in your specific bike, exhaust, and riding conditions with surgical precision. Made in the USA and designed for direct Power Vision integration, this is purpose-built hardware for riders who demand control over their fuel strategy.
