• Just set it up and ride; Precision EMS requires no laptop, no dyno and no downloads
• Unlike other so-called self-tuning controllers, this is a true self-optimizing system
• Adjusts instantly with little or no further adjustment
• Most self-tuning controllers get a little better with each ride, requiring countless rides for it to learn more than two thousand fuel cells; Precision EMS factors air/fuel ratio, timing parameters, load and temperature ranges and adjusts instantly
• Improves the performance of everything from a stock bike to a massive 135 in.
• Retains and makes use of the stock Delphi ECU
• Keeps OEM features and safeguards like ion-sensing knock protection
• Engine-load-based timing control
• Constantly monitors and adjusts using included wide band O2 sensors
• System includes Precision EMS controller, two wide-band O2 sensors, ECU shipment box and customer information sheet
• Made in the U.S.A.
