[dirt_track_racer_81]

Any one know how to convert EQ ratio to AFR..how is EQ compared to lambda..i know how to convert lambda to AFR.... .88 x 14.64 = 12.88 AFR

I know 1.00 EQ is 14.63 but but is 1.13 EQ? whats the formula?

I'm an idiot..i was tryin to be over complicated.. 14.63/12.8=1.142 EQ Ratio

A made a spreadsheet that does EQ to AFR - much easier on the brain

The formula:

EQ = 14.63 / AFR = 1 / Lambda

or

Lambda = AFR / 14.63 = 1 / EQ

The formula:

EQ = 14.63 / AFR = 1 / Lambda

or

Lambda = AFR / 14.63 = 1 / EQ

IF you want to be exactly spot on the 14.63 value above should be whatever value you've got in EFILIVE for B3601 "Ratio of Air to Fuel for Stoichiometry"
