Full-Range Programming:

The only truly full-range programming in the industry, AutoThority provides refinement and drive-ability second to none. Your car feels smoother, quicker, and more exciting under all conditions.

‘Soft’ Rev-limiter:

AutoThority typically raises the factory rev-limiter slightly to extend the engine’s operating range. Mainly intended for track and auto-cross use, as a way to ‘hold a gear’ during a curve, etc. our exclusive ‘soft’ rev-limiter offers better feel than stock and is much healthier for the engine.

Top speed limiter:

AutoThority can remove the factory set artificially low top speed governor for vehicles riding on upgraded high speed tires.

Custom Programming:

AutoThority maintains an extensive database of Custom Performance E-PROMs designed specifically for popular engine modifications. Because our standard E-PROMs are mapped precisely for stock vehicles, they may not be best for engines that have been modified. Even something as common as an exhaust system or air intake can dramatically alter the engine characteristics of some vehicles. Each of the Custom E-PROMs, that we offer, has been tuned on our dynamometer, to properly optimize for specific modifications or combinations of modifications.

Technical Support:

Our experts are just a phone call away, and can offer complete technical support on all of our products. Whether you are a new customer, or a longtime AutoThority client, you will receive straight answers to your questions.
