Default Firmware Update Changes Knock sensitivity?

Over the winter I upgraded from 1.3.4 that came on my REV MS3Basic to the latest 1.4.0 release. EDIT: Actually on 1.4.1 beta 2

On my first drive of the season I noticed my knock input is now MUCH more sensitive. With the same gain and window settings, I have gone from say 30-50% in boost to 85%

I have a hard time believing my engine is just magically that much more noisy.
Could this be a firmware change or should I be looking elsewhere?

1.4 is a big upgrade. And it isn't uncommon for settings to have to be readjusted after an upgrade.

I'm not aware of any such drastic change.
