Guest Anonymous Posted July 20, 2001 Share Posted July 20, 2001 Hey turbo guys just installed a TWM halmeter and I am trying to fine tune my car. Question 1: are all 3 wire 02 sensors the same meaning can some read richer than others Question 2: Currently I am running a small to4 w a s-trim compressor side I prefer to run on the fat side 11:1 or richer at 14+ boost. I am having difficulty reading the gauge. According to documentation I have seen, it can only read up to 12.5:1. For those who have use this gauge which indicator light should I be on with full boost. It seems the light never hits past the "i" in Rich Quote Link to comment Share on other sites More sharing options...
240Z Turbo Posted July 20, 2001 Share Posted July 20, 2001 1 light short of full rich should be about .89V 02. That should be sufficient and somewhat conservative. You should atleast be about 2 lights short of full rich on the gauge. The gauge only reads the O2 voltages and is solely a function of your O2 sensor. You cannot compare it to what someone else sees unless you have the same O2 sensor. Quote Link to comment Share on other sites More sharing options...
