Eq

What is EQ ratio and how does it work.

[mr.prick]

Equivalence Ratio (http://en.wikipedia.org/wiki/Equivalence_ratio#Equivalence_ratio)

[joecar]

EQ 1.00 means the AFR or FAR is exactly stoichiometric (regardless of fuel);
EQ 1.20 means 20% richer than stoichiometric;
EQ 0.90 means 10% leaner than stoichiometric;

Lambda means the opposite.

From mr.prick's link (his real name), you can summarize it like this:

EQ = AFRstoich/AFR = FAR/FARstoich = 1/Lambda
