What are the percentages for my airflow voltages for?
The airflow meter percentage or “correction” per AFM voltage braket is simply that, a correction for each voltage range. This allows the tuner or operator to show more or less Airflow to the Load map, which in turns moves it final load bearing on the load map. At 80% for the say 3.20v braket means that any airflow between 3.20v and 3.84v (standard GTST scaling) will only show 80% to the laod map. So if by default it was to land on load points 10 through to 13 then it would end up landing on load points 8 to 9 instead, 80% of the airflow load. You won’t have less or more power as the same amount of airflow comes into the system, it just affects how it is represented on the load maps. This allows the tuner to move the load bearing around on the map quickly and easily to effectively shift the map up and down. The benefit of doing this is you can quickly shift the load bearing around without adjusting 60 odd load points on the load map, for IGN and INJ settings for a given AFM voltage brac
