JamesW Posted May 26, 2010 Share Posted May 26, 2010 Ordered an O2 sensor simulator from magnumtuning.com today and can't wait to try it out. Is a four wire unit with two adjustment pots. Procedure is to measure the heater resistance of the real O2 sensor then adjust one pot to match this resistance on the simulator. The other adjustment will tune the frequency of the output sine wave as it changes above and below .5 VDC. I think this device will once and for all eliminate all traces of surging. I hope.
