Not like any other self-tuning controller, Revolution Performances Precision EMS is a true self-optimizing system; adjusts almost instantly with little additional adjustment. Simply set it up and ride; no laptop, no dyno and no downloads. Delivers instant results instead a little better with each ride; while most systems require the system to learn more than two thousand fuel cells over a tremendous number of rides, the Precision EMS factors in air/fuel ratio, timing parameters, load and temperature ranges then adjusts to them instantly. Will benefit everyone; from the owner of a stock bike to a full-blown 135in. Takes full advantage of, and retains, the stock Delphi ECU. Maintains OEM safeguards and features, like ion-sensing knock protection. Only system with engine-load-based timing control. Utilizes wide band O2 sensors to constantly monitor and adjust. Includes Precision EMS controller, two wide-band O2 sensors, ECU shipment box and customer information sheet. Not for sale in the state of California. Made in the U.S.A.

Precision Engine Management System delivers on its promise.
Does its intended function of delivering excellent driveability to my Harley. The closed loop feedback system with wide band O2 sensors just flat works without having to take it to be dyno tuned.
