It sounds like the simulated-tacho isn't doing a very good job.

One (off-the-wall) option might be to use a spare 7i77 analogue output
as a simulated tacho based on the Mesa-measured encoder velocity.
This ought to be worse than the system you have now, but there is the
option of tweaking deadbands and linearisation curves etc in HAL, so
at least you are not working blind.
