If we could wire a resistor between the rear o2 and the front o2 tricking the computer in seeing it within that range at all times....eliminating the need for cats at all, eliminating the rear o2sensors and eliminating the check engine light. The computer wouldnt have a problem with catalyst light off time cause it would allways be in the perfect voltage range. This may even be easier with the wide band o2's the z uses right from the factory. The voltage does not swing like old school o2sensors. This is just my nerd smog tech mechanic theory. anyone heard of someone trying this? I know I can find the information with my resources........is that a pimp idea or what?!
