There are two methods of obtaining analog lambda which are identically the same thing. The first method has the user pre-calculate two constants (i.e. the user pre-calculates this: AFR pid divided by stoich AFR); it evaluates in one step (it evaluates lambda directly in one calculation). The second method evaluates two steps (it evaluates the AFR pid first, then divides it by stoich AFR to obtain lambda).
Method 1:

Method 2:
Using LC-1 as example:
. . .
You could also reduce those two pids into a single pid:
Define CALC.WO2BEN1 (CLC-00-110) to be {GM.EQIVRATIO}*({CALC.AFR_LC11}/14.7)
