The Python pep8 project was forked to the pycodestyle project nearly two years ago. The pep8 project is no longer being maintained/updated.
As far as I can tell, neither Komodo 10 nor Komodo 11 are using pycodestyle. They're still using pep8. I've reached this conclusion by examining the contents of the lib/mozilla/components/koPyhonLinter.py file.
While I can certainly run pycodestyle manually from the command line, I do find that to be a disruption of my workflow and not as convenient as being able to have Komodo flag issues for me in near real time.
