Datalogging

I've been looking through some datalogging recordings that I made a while back from my Z4MC from the ECU via the OBDII socket. The datalogger will record any of the PIDs (Parameter IDs) that the ECU will divulge. The Z4MC will simultaneously yield both Airflow Rate from the MAF but also Airflow Rate from a MAP as shown in the graph below. I am confused! Does the Z4MC have a MAP sensor and if so what is the part number and where is it situated? If not, I wonder what the datalogger is recording?
