So it's
harkes himself (
repainted without notice).
I might need to elaborate my impression from the video then.
The topic has been discussed here too many times to mention.
ovekvam, in particular, has written quite a book spread over those threads.
Here's just one for example:
Open-diff vs. E-diff- vs LSD (F20 related).

What is "E-diff"?
DSC is a
complex system (
this document, page #18, looks kindly quoted) working with
all the wheels (brakes) and the engine (power):
. "
Quaife Helical" is what it is - an LSD.
How can you compare those? Put the simplest, "Quaife Helical" is what helps to drift, DSC(/DTC) taken as "E-diff" is what prevents drifting (still failing to overcome the laws of physics). When you
choose DTC to "allow the wheels to spin" it is like you disable LSD to some extent. So taking as "E-Diff" the Active Differential Brake (ADB-Sport) feature (activated "When DSC mode is off" - does that make a bit of sense already?) looks the only correct approach to challenge "Quaife Helical" (which needs not DSC "wrapper" to show itself either, perhaps).

How do you know?
You heard the left wheel and checked the right you say.

When DTC "E-diff" steps in the instrument indicator flashes. Quaife Helical is always there (when it's there) and it's claimed to step in faster even than the ADB ("DSC OFF") "E-diff".
Regarding the 0.1 second - how much does Quaife Helical weigh to add to traction?
