Hey Ananth,

Isn't jetting for carburetted cars. As far as the MpFI cars are cocerned the ECM will readjust the extra AFR automatically if i'm not mistaken.

True, but is it possible for them to adjust for correct mixture as speeds rise? Because you will have a mild ram-air effect which leans out the mixture at higher speeds.....

Yes the ECM will if its closed loop.

If your ECM is closed loop type and your injectors are able to spit a bit more fuel then yes the ECM will automatically adjust for the RAM effect.
Bye and wear your seatbelts

well guys you can differ all you want. then why do all 'cold air intakes" place the the air filter near the bumper below the engine bay?? iam not talking about the short ram system but the cold air intake.
viper and doc you guys are absolutely right.

Not all cars have MAF sensors. Some will calculate airflow using TPS, rpm, ambient pressure etc.

I know that. The point was that there is no jetting involved. The electronics and sensors will do the necessary changes.
