Hi all,
Got a question about O2 sensors - I'm fitting a 1uz soarer engine into an old lotus. I have the soarer manifolds with the O2 sensors but not the sub O2 sensors post the CATs. My car will not have any CATs.
I intend to use the primary O2 sensors in the manifold, and not use the sub O2 sensors. Can anyone tell me:
- Can the function of the sub O2 sensor be simulated with a resistor from the sensor wire / ECU pin to ground?
- If so what value of resistor do i need to install in place of the sub O2 sensors to make the ECU think the exhaust gas is how it should be post a CAT?
- Assuming working primary O2 sensors, and a standard working ECU, will the engine run ok like this?
Any help or comments appreicated. Thanks, Mat.
