I only need values from MLHFM (voltage and air flow) for old HFM2 MAF, one that AEB and AGU uses.
Can be excel, code in post , or simply bin and xdf, OLS...
Ofset also
If M3.8 work like ME7?
Thank you

No it does not work like HFM5.
There is no 5V reference, the signal goes higher than 5V IIRC, and there is no reverse flow measurement.
Don't even try to connect one to a ME7 ecu.

PM's will not be answered, so don't even try.

I need for some other project to mesure flow with arduino
Yes i know it goes higher than 5V.
