Wide band VS Narrow band sensors?
I asked this on another forum but didn't get many replies.
So I try here.
I wonder what kind of design our oxygen sensors have on 1998 - 2000 eüro/US market W202 C43 AMG?
Do we have wide band oxygen sensors or narrow band oxygen sensors on our cars?
Eüro/Djapan/Australija market C43 AMG had only 2x oxygen sensors without CEL option, where the US market cars had 4x oxygen sensors with CEL in cluster.
I believe that the MY2000 Eüro/Japan/Australija market C43's had CEL in cluster?
Correct me if I'm wrong?
Wide band oxygen sensores do they measure A/F ratio in a wider scale gathering more information from exhaust fumes?
Narrow band oxygen sensors do they measure A/F ratio in a smaller scale covering less information?
I was browsing Fleabay and saw some 52mm gauges for narrow band VS wide band monitoring.
people who mod their car with HD turbos or Super Chargers should they buy the wide band gauge for more accurate readings of AFR?
you guys who did the stock engine swap from 4.3L to 5.4L on your C43, did any of you install this gauge monitoring AFR if you run your new 5.4L engine with stock C43 ECU?
according to BenZslo, running the 5.4L engine with stock C43 ECU without doing a re-flash to E55 software will cause the 5.4L engine to run a bit lean, but will NOT be harmful to cats.
Is there any point monitoring the AFR with a gauge?

Kowalski, happy bed time reading. Check under automotive applications and you'll sure fall asleep quickly...

thanx
maybe we have narrow band probes on our cars, what da heck do i know?

Neither do I, nor that I really care providing everything works as it should
