Connect the computer to the vehicle. Start the car. Take the MAXISYS computer and select "Module 1 Engine Control". Select "Current Data" and then "Advanced Measured Values". Now locate the Mass Air Flow (MAF) entry and observe that the values change according to the acceleration while the car is in motion.
