Changing injector pulse rate at idle?

This would allow you to run longer injector pulse widths and stay
out of the non-linear region, to be sure.  However, note that your
fuel atomization will suffer.  This could cause worse operation
at light loads.  Just a trade-off to be aware of...

Yet another technique is, of course, to use two injectors per
cylinder.  Use one small injector alone for the low-load stuff
and kick in the other at higher loads.
