Hey all,

I have seen time and time again on these boards where it is stated 450 mV is the correct crossover voltage for our cars to stay "around" 14.7. What I find interesting is that factory setting is actually 425 mV. Granted this is not much but it does basically put our cars on the lean side...if in fact 450 is correct.

So the question is: is 450 correct for our cars to dance around 14.7 or is this a voltage just pulled out of the air? If so, why is a stock 95 PCM set up for a 425 crossover voltage?

I ask this becase when I set my old Hawk up on the wideband and dynoed, I was in fact leaner than my PE enrichment setting by about 0.1 to 0.2 thus confirming that the MAF calibration I did was actually a slight bit lean. FYI, the MAF is calibrated using the O2's.

Someone give me your thoughts.

Ben
