Testing hitachi MAF

[HMLyder]

Have connected the ECUTALK and am monitoring the MAF data.
Does anyone know what data it should have?
At idle it's showing 2V and 4V at 3200 rpm.
And how do i know if it's faulty?

that looks about right, your voltages look about same as mine.
examine you ecutalk logs carefully, in particular look at the advance reading, do they alter? Pretty much all readings will be altering as you drive, if they don`t get more info on the stationary ones.(your symptoms are similar to what i had)
