I only sensed the exhaust coming out of the head,not after the catalytic converter,so u can take that off,i believe Ford used an Intake temp sensor(IAT
) as well as a Manifold Absolute Pressure Sensor(MAP),so if you take the IAT
sensor and put if where it gets cold fresh air,the engine always thinks its getting cold dense fresh air,so it will always give the engine more fuel (not recommended for a worn out motor, or for winter) but these are just a few things that you can do to "Bypass" the Computer. OBD
II made it almost impossible to "Outsmart" the computer by doing these things, mostly cuz theres two O2 sensors for the exhaust,a "Before" and "After" the Catalytic Converter,which means you cant take it off...
