With the possibility of underutilizing your ATV’s fuel through poor consumption, you will definitely want to keep its fuel injection rates at an optimum using a fuel controller. Z-Fi MX Fuel Control systems smoothen out throttle transitions for better air passage into your engine system. The immediate result is a gain in horsepower and torque. In addition to this, a default fuel map programmed for powered-up performance is already integrated in the Z-Fi MX Fuel Controller once you purchase it.
