MAF output signal

I have the PLX R-500 and can log 2-speed(Hz) channels and 4-analog channels. Is the MAF signal wire #90 Hz or volts? The PLX website says it is volts. If it is volts is there a formula to convert g/sec to Hz?

Technically its both.. I recall the voltage output being for something, but the signal your concerned about is the Frequency, and you can use the digital (speed) channel to view it.

I don't know about what you can log with the raw signal, but in my research for the MAF scaling, I came up with an equation for g/sec from the Hz value. Although, if you are just logging to the 1600Hz max, it may not help that much.

Yes for what he wants to do its in HZ, its a digital value, and can be read by the plx as a speed input (Frequency)

For all intensive purposes thats all the info he needed.
