Last time I checked the TPU and eTPU are timer modules, so regardless of the units presented to the CPU, crank speed is measured in clock ticks. Hence there will always be errors when the crank accelerates or decelerates. 
 
A good interface to even the "old school" PMM/PMA routines will present in terms of a crank angle. It would appear that this new eTPU function just does this for you perhaps.
 
I can not find an equivalent of the eTPU's angle clock function (other than PMM/PMA) in mask G or otherwise. There is a degree clock which is much more limited in function. Can you please research this and find a link for us?

Crank angle  domain is far superior to PMM.  I believe TPU mask G has it.  No more free running counter error if the time between sparks ( rate of crankshaft) changes.
