Trying to understand the DME

Thanks thstone!

I do plan to take it to the tuner for a re-map, however if one can convert the MAF-signal eg via an arduino to make it all fly, that would be neat for everyone wanting to switch to the 987 airbox/MAF-tube without having to re-tune.

There is a signal range returned from the MAF to the ECU. This value is compared to a table for air flow so to speak, each millivolt or milliamp has a value. So the return signal triggers an exchange in the mix calculation. So in the end the signal has a range in the ECU and a maximum value in the table. The table has to be changed.
