Resolution.

[Espen Hilde]

Hi !
Seeking a good solution to high powered streetable engines......some
questions pops up....
Where is the weak link in the Efi system when it comes to resolution?
MAP SENSOR: Going from 1 to 2bar halfs the resolution....3bar even worse.
Is staging map sensors a posibility?
0 to 5 volts  :  how acurate can the ecm measure the input from the
sensors?
Is 0 to 10 v better?  or frequensy?
ECM: Computers ability .
INJECTORS:Huge injectors on idle or high rpm must give bad resolution.
How fine can they do their task?

To expand the range of the system we have some options,Using staged
injectors,peak and hold drivers,  sequential efi and increasing rate fuel
pressure regulator. When triggering the injector 
just once insted of two each revolution you have a better chance of
avoiding 
to be in the non linear part of injector delivery at small opening
times.And one longer time means more acurate than two small?Batch fier is
once each 
revolution isnt it?
Is it possible to say what maximum injector that can be used  with a
reasonable idle resolution?
Is there some good info on this aria anywhere?
