Title: Logging MAF sensor voltage
Post by: vtraudt on December 12, 2015, 05:34:15 AM
Could not find the MAF VOLTAGE value in the logging parameters of Me7.
Not available as a loggable parameter?

Thanks much. Had used search term Massenstrom, but is listed as {HFM-Spannung}.

Correct scaling is * 0.0048828125

So by logging MAF values in g/sec and volt, I can verify if the MAF is properly scaled?

No, you'll see the Volt vs map curve post any other corrections, scaling is another story.  I use the Voltage to check for a bad maf normally

e.g  You could say at 4.5v 200 g/s in the map when the flow bench say's 185 g/s, this would not show up in the logs, but should show in your fuelling

Needs an update but in General his explains it.
