Thankyou for purchasing an Easitune system.

This system was designed to make tuning of your race engine easier and more accurate, as it tells you the MIXTURE, not the exhaust temp.

With the advent of intake & exhaust mufflers/silencers, earplugs, etc, the old “seat of the pants” tuning is verging on the impossible for the average racer.

A simple, ultrabright LED display is used, to depict the fuel mixture at a given point in time. The information is derived from a lambda sensor. (A modified sensor is used for twostrokes.)

These are the same sensors as used in your late model family car.

PLEASE READ the fitting & tuning instructions.
