Trying to understand the DME

[Robert986]

Brilliant answers thstone, thanks!! Will look into that book!

Some more reflections:

"The OEM map is static" -So, does this mean that there is only ONE fuel map used in all states of operation? I was expexting at least a separate map at WOT, giving a bit fatter mix for cooling.

The main reason for my interest is if I would be able to use the 987 MAF-tube (as a part of switch to the 987-airbox and 997 throttle/Plenum) without a re-map. Let´s say I manage to convert the MAF-signal so the voltages going into the DME represents the actual airflow.. Would that be enough? I mean then the DME would get the correct airflow into it´s calculations, the difference should be that the new intake system would allow for a better airflow, giving more air. Then I take it that the STFT+LTFT would compensate so it would all be working.

However.. Since the imroved airflow + extra fuel will give more power, would I then need a fatter mix at WOT for more cooling? Or will everything be ok?
