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.

for what i know its hz...

 

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.

 

Thanks guys I am leaving wrok here soon and will try it when I get home. I love my military job show up at 0500 and leave at 0900.
