I have just read your first post on this again and you are talking total bollocks
Traction control is only triggered when the sensors detect a differential in wheel speed. I.E the back wheel is losing grip as it tries to drive the bike forwards where you claim that there is no possible loss of traction. It is sensor monitored not fueling
The S mode to which you keep referring adjusts the level of TC interference, Enduro ( or whatever it is called) pretty much turns it off allowing the rear to spin up
I will admit that in "Rain Mode" it can be overly obtrusive but other than that on the 2 Gs i owned, a hex head and a LC the TC only kicked in when i was a ham fisted idiot on cattle grids and the like so either your bike is fucked or you are a hamfisted idiot
the ASC has two levels of intervention -
in default mode
1) mild holding back under a very slight differential of two wheels speed sensors that have been giving a steady matching output
2) an abrupt total cut of power, where it more often than not mistakenly believes there is a significant lost of rear wheel traction
the first is mildly irritating and could be undetected by an average rider (as appears to be the case with many replies here)
the second comes to light under more spirited riding and can be irritating and is often dangerous when pulling away or needing full power - where the limitation of the system misunderstands the lively change in rear wheel speed over the lagging delayed response from the front which might be late to the party if the front gets a little air borne
in S mode
1) is seldom triggered (except in very low grip situations where you shouldn't be trying so hard)
2) the level of differential is expanded slightly over coming all the pitfalls of the default setting
S still gives substantial wheel spin control by limiting excessive spin, allowing a skilled vehicle user to make sensible use of minute levels of speed differential to extract higher performance and gain more fun from their vehicle....
default mode cuts in well before any obvious loss of grip becomes problematic to a skilled rider.

is what allows uncontrol slip of the rear wheel
