MAF logging with an E40 on a Grand Prix GXP

[machine]

I am looking for some help logging my raw MAF signal on a grand prix gxp. I have the upgraded 2 bar OS and would like to begin tuning on my MAF, however when I log the MAF it shows 0 Hz. I have logged the car with the MAF plugged in and unplugged and there is a difference in A/F. There is also a noticable difference at idle which makes me feel the MAF is working. Could anyone suggest why it is logging at 0 Hz?

Thanks for the help.

Is that using the SAE.MAF PID?

I just did a 05 GTO with the e40. First one I have messed with, you need to have the right pids and have the map/graph set to those pids.
