o2 target voltage / AFR

ITR 1102 · Post by **ITR 1102** » Fri Aug 07, 2009 2:17 pm

What is the relationship between the o2 target voltage and the closed loop AFR?

Ex: what is the desired AFR if target is set at .43 as opposed to .51?

Is this option only used to compensate for differences in the o2 sensors in order to properly reach stoich, or is this used to change the target AFR for better economy?

It can be used for either. The target is the voltage you are shooting for.

is there a chart that shows the typical voltages to air to fuel ratio to use as a guide?

You will have to look at the documentation for the sensor you are using.
