MAF algorithm

[peter paul fenske]

Hi Gang:
Although I probably am not going to get involved with something as
tacky as an MAF I am curious as to the fueling calculation involved.
Here is my understanding so far.
First off synchronous fueling. With the systems I play with the
injectors are still synched to the engine revolution. This appears to
be unnecessary with mass air flow since an assynchronous pulse with 
width pro to mass flow(desired AF ratio), a coolant correct( to modify
AF for temp), a PE( for power enrichment) and perhaps a voltage corr
(for injector var due to bat voltage).
But why synch?
In order to use MAF for sychronous injection it appears you must
divide the airflow by RPM to get the load. Then set the base? pulse
width.
I hope some of the more empowered individuals on the net can help.
Tnx always: peter
