MAP avg uses engine module callbacks (#475)
Browse files Browse the repository at this point in the history
* use engine module callbacks

* happy tests

* happy small-can-board

* interact with map avg via module

* simplify map avg init

* tweaks

* omit module to disable it instead!

* unnecessary guard

* minor cleanups

* unnecessary branch - lookups for these tables are fine at 0 rpm

* oop
