Hi,

anyone know the max rate of mass air flow ( maf g/s ) and the max mafv for M15a engine.
im getting max mafv around 4.10 at 6700 rpm and as per some calculation it says the max of my mafv is 4.27
and the manual says it can be reach to 5v but never mention the max g/s

Is there a chart for the mafv vs maf g/s for m15a engine ?
I tried to search online but i haven't found any info

also what is the MAP Voltage with ignition on engine off
Mine is 3.88v at 100 kpa barometric pres

i hope someone can help me with that

I would expect the voltage to be closer to 5V.

Why do you want to know the max air flow rate?

yes it should be closer to 5v but mine never goes above that number.
that's why im asking if anybody ever measure the max mafv.
if anybody using piggyback ecu it easy for them to measure the max mafv by looking at their log file by doing WOT PULL FROM 3000 - 6800 for M15 engine.

The max air flow rate will help me alot with tuning my intake.
