This is my third attempt to get an airflow reading from the MAF sensor on the flowbench that will match relatively close to what the stock MLHFM curve predicts airflow to be.

The latest results are the 5.1x values.

I’m thinking that it is worth trying to adjust the output from the 5v power supply to pull the green line down and get it to match the stock curve.  Possibly the 5v supplied to the MAF sensor should in fact be slightly more than 5v.
