[Diy_efi] How many Bits for PWM injection driver?

[Les Dittert]

I tried several archive searches, but didn't see any mentioning if
8 bits would be too coarse. My gut feeling is that I could live with
256 steps.
Would it be noticeable during mild throttle settings?

mmm These are fundamental questions, I seem to recall some discussion of
this in the archives going back some years <phew>
