I recently saw a gauge in the summit racing catalog that consists of an oxygen sensor and a gauge that tells you the fuel air mixture. What do you think of using this for fueling a hybrid. I f you weld he 02 sensor bung into your chamber and presurize your chamber then inject fuel until the fuel air mixture on the gauge is correct then fire.

Most oxygen sensors mount in the exhaust. They require high temperature to operate and measure the remaining oxygen after combustion. They are not suitable to a single charge shot prior to ignition. Read the installation guide for it. The oxygen sensor goes in the exhaust. It measures the remaining oxygen. Too rich leaves too little oxygen and unburned hydrocarbons in the exhaust. Too much oxygen indicates too little fuel.
