I don't know the exact pulse width resolution, but I'm sure Ray Hall can
give you the specs. I use the SMC, similar to the SM2, but missing a
couple inputs and outputs for traction control, idle air, and some other
niceties.

It has no problem controlling large injectors (96 lb/hr) at idle. I'm
able to make small corrections in fuel delivery. Ignition is similarly
accurate. I understand they're also coming out with a knock sensing unit
that will interface with their ECU, and do the usual individual spark
and fuel adjustment. I believe it will also reduce the turbo boost, if
necessary.
