With the esp on , if the tires spin with the wheel turned it goes into limp mode.
I assume this is the safety built in the system.

2008 Wrangler X non rubicon.
So am I LSD or what?
That's the throttle control described in post #17. Sometimes it's advantageous to let the wheels spin, so being able to disable the throttle control part of the TCS is good. Most of the time, though, reducing the throttle during wheel spin will let the tires grab again. Most drivers don't do it, so it's programmed to do it for them.
In the winter, I see lots of drivers just flooring it when stuck. They are the ones that need a computer to think for them.

I guess I am still quite confused too. Does BLD stay ALWAYS active? Even with TCS or ECS partially or full off?

"A feature of the TCS
system functions similar to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This
will allow more engine torque to be applied to the wheel
that is not spinning. This feature remains active even if
TCS and ESP are in either the “Partial Off” or “Full Off”
modes. Refer to “ESP (Electronic Stability Program)” in
this section."

Cool
Thanks All.

Bout 90% on road so couldn't justify $$$ for traction enhancement.
Looks like what I got will be just fine.

Yes. It's addressed nicely in the paragraph you quoted. They just don't come out and actually call it Brake Lock Differential.

Article by a chrysler engineer
Chrysler Blog - Jeep Brake Traction Control Explained

'Independent Testing' info to back up the comment about the truetrac not wearing out like clutch limiteds.
Independent Testing



The truetrac definitely beats the snot out of the stock limited, but yeah, for your stated usage, wait until it's time for gears to think about adding traction aids.

These are both excellent, thanks for the awesome info. I will look at a truetrac if I decide what I have isn't enough this upcoming winter.
