I have talked to an old mech and he says that reading maf on a diesel is the most useless method of determining fuel consumption he could think of. He said that would just make random numbers that have no bearing on anything.
He said most diesels (especially older non-turbo models) have a static fuel amount directly tied to the throttle position and RPM assuming of coarse the motor is warm.
If this is true why isn't the fuel rate computed using a different method such as by displacement, RPM and throttle position? Most OBDII diesels have TPS right?
Would this be possible to impliment?
