more air = more fuel?!?
Dudes,
me and some guys wonder, what the ecu does with the information from the air-mass sensor..
Does the ecu change the quantity of fuel relatively to the quantity of air that streams in ? Or is the
quantity of fuel unchangable and an intake or K&N Filter will only affect better breathing ?

Re: more air = more fuel?!? (austrian ITR)
Ideally the computer would compensate and add more fuel upon finding that there is more air available.
However, the ITR (and most Hondas I believe) don't use a mass flow sensor, they base calculations upon Manifold Air Pressure (MAP) sensor readings, as well as numerous other operating parameter signals.

Air mass sensor? Never heard of it. The ECU will keep the A/F ratio at a certain value, so more air = more fuel. The ECU measures the amount of air with air pressure sensors, air temp sensors, throttle position sensor and maybe more.....

Air Mass Sensor = one of those hot wire throttle body air flow sensors (wherein the wire is kept at a constant temperature by the computer and the "mass" of the air flowing past the sensor is determined to be proportional to the current needed to keep the temp of the wire constant). FWIW

ford likes to use this method. it is good, but one problem is the air streme needs to be very steady going into the MAF (mass air flow sensor) or it will get bad readings. KN filters doing steady the stream enough going into the MAF and aren't very good for a ford, just in case one of you were getting a 4.6L mustang any time soon

They don't exist in Honda's. So why do I need to know this?
