If you’re reflashing an OE ECU that relies on a mass airflow sensor, then all of the ECUs load calculations are based off the measured air mass from the MAF sensor. Any time we make changes to the intake system, airbox or MAF sensor itself, this may require the MAF calibration to be corrected in order to ensure that the MAF is reporting the correct values. In this webinar we’ll discuss how we can do this in the HP Tuners software on a GM platform.
