Hi all,

Background: I've got a car which uses a simple Vane airflow meter, which
consists of a spring loaded flap, of which the engine airflow pulls open
to varying degrees. I wish to use a mass airflow meter as its
replacement, due to its lack of moving parts and larger flow.

The problem: the vane airflow meter was designed to have a certain
amount of overshoot, to act as an 'accelerator pump' in carby terms, as
acceleration enrichment.

I wish to create a pic-based board that simulates the effect of a loaded
spring. Is there anyone with a natural gift at physics formulas etc that
would be willing to assist me in the design of such a simulation?

I intend to post the design up on a page when I'm finished, so I am not
looking to make a profit off it at all.

Thanks,

Dave
