hi to all
in my ongoing study I am having difficulty in calculating the afr
then I know that the afr is the ratio between the intake air / fuel injected
being that the edc16 work to "torque" I have come to understand that in order to find the afr at a given time proceeds so
- it is located on the torque limiter, the value that interests us, here, example at 4000 rpm 142nm
- you go in the map pair - diesel and I try to 142nm at 4000 rpm, and I find diesel required approximately 29,2 mg
- now I should find the map fuel - to-air ( which I can't find it,that ... is the lambda sensor, the upper and lower???) to find the related mg of air that goal that takes the car

and, finally, the relationship between mg air / mg of diesel fuel = ratio AFR

my problem is that I can not find is the famous map fuel-air and also wanting to find the air "sucked" by reading in the diagnosis of the MAF, but I have found values in Kg/h
