Generally the updates are improvements on the dynamic timing advance features (aka ramping, boost, etc) to improve performance of ‘stock’ brushless motors. The programs are generally available on the manufacturer’s sites.

Somewhat falling out of favor as the stock class is trying to move back to it’s intended role as a slower class with ESC no timing rules, commonly referred to as ‘blinky’. Blinky meaning the special light sequences that indicate the no timing mode.
