EFI without a lookup table

[Bruno!]

Hi everyone,

Is it possible to have an efi computer control the engine entirely in 
closed loop? I'd like to design a ecu which does not rely on having to be 
dyno-tuned, or other ways where the engine has to run at different loads, 
speeds, etc.

The rationale behind this is I want to be able to design the computer, 
plug it in, and control the engine from day one. I understand that there 
are more things to consider, what they are exactly are slowly coming to me.

For a start, I was thinking of using a MAP, TPS, and a crank angle sensor 
(for RPM) and intake air temperature for airflow metering, and an O2 sensor 
for mixture. 

When using a hall effect sensor, what is the material that the metal vane 
that passes through the gap made of? Iron or aluminium?

Any thoughts or suggestions would be most welcome. Thanks.
