5.0L (1979-1995) Mustang Technical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.

Definately use the sensor AND the housing from the 94-95 Mustang.
They can be found on other cars as well... I've pulled a couple from 4.6L cars...

This MAF housing actually bolts to the intake, as opposed to the Fox housing which slips into the intake tubing.
You can find the adapters on ebay most the time. It is a 4-bolt flange adapter for a 70mm MAF.

The sensor part number will start with 'F2VF-******'
Any other sensor in the 70mm housing and it won't work with the Fox ecu's.
The 94-95 Mustang MAF can only be used on Fox Mustangs when 19Lb injectors are still being used.

You want the air meter you're putting on to have as close to the stock resistance for the same airflow. For example; 2.5volts to the stock computer is about 90cfm, so ideally you want another air meter that at about 90cfm is sending the same signal to the eec, around 2.5v. If the voltage is off, depending on which way it's off will make your car run richer or leaner.

& for the record 356cfm is a huge difference, that is about the equivalence of 235-245whp difference.

I wouldn't suggest sizing a MAF meter this way.... The output from the MAF is not linear, and there is no guarantee that the curve rates will be the same.

In other words...
2 different meters may 'match up' at 2.5v, but be WAY off by 3.5v....

You would need to evaluate the entire MAF output curve.

Of course not. I was just using 2.5v as an example. I agree.

Hey, collage is a form of art. College however, is an institution of higher learning... ***
