Hi Mike,

Why would you change to Batch mode at higher power RPMs, why not just set
the injector phasing to fire at the back of the valves when it would give
the maximum cooling?  I may be wrong but I would think Batch firing would
cool some valves better than others.

Is this so vaporization is the same in all cylinders?

Thanks,
