What Is a Mileage Blocker?

A mileage blocker (also known as an odometer stopper or CAN Bus filter) is a precision device that intercepts the speed signal to your vehicle’s odometer and prevents mileage from being recorded during testing. Unlike cheap plug-in devices, our blockers work across all ECU modules simultaneously — making them completely undetectable even by professional diagnostic tools.

They are designed exclusively for dyno testing, off-road use, and performance evaluation on private property.

Perfect for St Louis’s Track and Performance Scene
