What does this mean look into duration maps? I looked yes 140 has shorter duration, but longer duration means more power so 170 has longer duration. What's the point?
I dont know if BKP has DPF, but i as far as i know nozzles in PPD140 and 170 injectors are same (diference is in piezoelectric element). So maybe higher durations on 170 are due to DPF? Just assuming
