Pretty much all profession dyno tuners use headphones. Your ear / brain has more signal processing and computing power than any chip.

There are lots of system out there such as the one below, educate yourself:

Not really! Tuning engines without knock control is problematic, e.g. the 911 3.2.
The variables which are not controllable, typically contribute the most to detonation and can't be fully simulated during dyno runs;

1. High engine load conditions like climbing a long steep grade.
2. A hard acceleration on a very hot day in the high RPM range, e.g. a track day.
3. Compounding conditions 1&2 is having a fuel octane level which is less than what's presumed, i.e. a lower octane than what's listed on the pump. It happens!

Those also buying the so-called 911 3.2 "performance" chip typically overlook these issues too!
