My car (LS1 VZ Commodore, Australian) has its cats mounted very close up to the exhaust manifolds. The oxy sensors pass through heat shields that cover what little pipe there is and I want to add a wideband.
Has anyone added a wideband to a VZ? If so what about the heat shields?
My wideband can act as a narrowband simulator, so this is option 2.
Left field option, could I just use one oxy sensor to run 2 inputs on the PCM, presumably the PCM has at least 1Meg Ohm of input impedence so it should not load the sensor voltage.
Lastly I have attached a pdf of the engine wiring diagram and to my eyes the PCM does not monitor the sensor heater, so I should be able to use this to run the wideband controller.
Thanks in advance, Steve
