| This function probably helps most with a GM MAF setup run straight to the ECU using ECMLink's GM MAF integration option. That particular configuration produces a pretty large number of MAF sample points for fairly typical driving conditions (easily ranging from 500hz to 2000hz for simple idle and cruise conditions). So having a tool which helps establish a decent starting point can be very handy here. | This function probably helps most with a GM MAF setup run straight to the ECU using ECMLink's GM MAF integration option.

| Make sure the engine is at full operating temperatures. You don't want to mess with coolant based variations at this point. You want to stabilize everything you can first and then adjust based on the one variable left (presumably airflow variation). | Make sure the engine is at full operating temperatures.
