How to get injector "on time"?

[Brian Lewis]

Hi all,

I am designing a simple FI controller out of an 68hc12 using C. I plan on
measuring MAP and RPM and using these parameters to lookup a value for how
long the injectors should be open in a 2-D table. My question is how fine
must the resolution in the table be for smooth transitions between
operating conditions and will I have to interpolate between points. Thanks
in advance.
