removing mass airflow sensor

I want to put a supercharger and a cold air intake on my car but it would mess with the computer cause of the mass airflow sensor. Is there anyway around it?

Uh... with a Mass Airflow sensor it should adjust better to a certain degree before you will have to mess with the PCM's programming. That's why many 5.0L owners with a speed density (Manifold Absolute Pressure sensor) based fuel system convert to mass air based fuel system. It better adjusts to changes in airflow. Speed density can only adjust so much before you have to start tweaking.

Re: removing mass airflow sensor

The Ford engines monitor the incoming air temperature and adjust for it.

It is possible to run without a MAF if you convert to an aftermarket stand-alone ECU. These can use a manifold absolute pressure sensor reading to determine engine load instead. This approach can make sense if you change the engine to the point the stock ECU cannot compensate for it, especially if you cram in more air than your MAF can measure. It depends on how much boost you want to run.

Also be sure your cold air intake can work with your supercharger of choice. Many cold air intakes won't.
