    Hi,

    When I drive any powerful car with traction control turned on, it works just fine almost always. However, when I floor my accelerator while cornering and let my rear end slide, the traction control works for me only 90% of the time. The other 10% of the time, It doesn't do anything. The ESC blinker only doesn't blink even though my tires are just skidding completely. The problem goes away only after I release the accelerator let the wheels stop spinning and waiting for a few seconds. Then when I floor it, it works like it should.

    This weird behavior makes me loose control in corners and my faith in TC.

    On which setting is it ? On settings like sport maybe it thinks you're trying to drift and thus let the wheels spin ?

    I tried comfort and sport mode but the behavior I mentioned above still persists. Also when I did further digging into drivemodes.jbeam I noticed something called 'electronicsplitshaftlock'. What does it do since it is set to default in comfort, 0.25 in sport and disabled in drift? I know when you disable it, it gives 100% power to the rear wheels in the Bastion so that you can drift.

    Currently I am testing to see if I can fix it by playing around kP, kD and kI values in tc.jbeam.

    I guess it does exactly what its name says, it locks the splitshaft with the given ratio. So in comfort mode the front wheels receive the same power as rear ones, in sport they receive up to 25%, and in drift none.

    @Agent_Y That's what I thought as well, but apparently that's not what it does. Setting it to disabled puts all power to rear wheels for sure but any other value(even 0) seems to supply a constant amount of power at any other value.

    So maybe it acts like a limited slip differential with other values, with the value being the slip ratio or something? Idk

    Keep in mind that neither stability control nor traction control are performance-enhancing devices. Overconfident with traction control or your driving skill can end up in terrible accidents.
    Thus, you shouldn't have that said faith in the first place. You should practice throttle control instead.

    As was noted before, the software is not there to fix all of your inputs. If you're deliberately doing stupid stuff, the software won't be able to counter that.
    Additionally, it also self-deactivates at some point when it sees that the driver is just messing around and not driving realistically.
