The Max Energy E-CON Economy Power Programmer from Hypertech is designed to offer better fuel mileage and more power, without the added cost of other high-performance features, which may not be utilized. The E-CON is programmed with Hypertech’s Max Energy Tuning, optimizing fuel and spark curves to increase horsepower and torque at wide-open throttle and more miles at part-throttle. Hypertech customers report 2-to-6 mpg gain and a substantial increase in horsepower and torque. For an additional charge the E-CON can be upgraded to a Max Energy Power Programmer, via an online download, to include all Max Energy features for that vehicle.
