    Evening all.. Can anyone confirm what Frequency Units are being used for the MAF Sensor Scaling?

    Thanks in advance VFTuner

      Matt -

      If one needed to adjust / rescale what table would be used?

      The MAF Scaling frequency pictured in the above message is too low in grams/sec ending at 16.5 to be utilized?? Even the High Freq Table is not enough ending in 53 grams/sec....






      Assume this is a multiplier table... Is that correct? And if so, would the 3 Trim tables be used to increase or decrease the multiplication factor for the MAF?

      If that is not correct, can you tell me which map is used to adjust the actual MAF scaling function?
