MAF sensor

[Rootsey1]

Hi,

would anyone know if the MAF sensor also measures the incoming air temperature.

Thanks

No, it measures the mass of air coming in as as compared to a map sensor which measures pressure so also needs a inlet temperature sensor. So the maf sensor already has temperature as a component of its measurement. There's is as far as I know no need for a inlet temperature sensor for the ecu even on a turbo, driver/tuner might be interested though....

Yes it measures the intake air temp also. Without the temp it doesn't know the density.

dizzy engine no, coilpack engine yes (combined maf/iat sensor)

I've a dizzy engine. Any idea were the air temp sensor is fitted. Been reading up about tricking the in coming air temp with a resistor to increase the air/fuel ratio. Has anyone tried it.

You don't have one as you said you've got the dizzy engine and not the coilpack one. See Frank's post above.

You may be able to achieve a similar thing with an adjustable fuel pressure regulator.
