No, a speed density computer picks up a frequency signal from the MAP, while a MAF sensor has varying voltage output signal. Also, i belive the trucks with MAF have a couple more O2 sensors and stuff.
Yeah, non interchangeable. I shouldn't go on, but the type of input the computer receives is irrelevant. Even it the map sensor was a voltage varying input to the computer, attaching a voltage varying mass flow meter to the same input would not work. You have a speed density computer, and a mass air computer which are not one in the same.
