I really like my '08 as its the last year of the wagon body style. But one of my biggest complaints is the lack of an electronic brake-based limited slip (TCS/Xmode). I've gotten stuck in two-wheel spin many times even with the stock rear mechanical LSD.

Are there any software modifications that have been done to add electronic brake-based limited slip functionality on older models with ABS? The basic hardware is there except the electric brake actuator so I understand any software-only mod would require driver press of the break pedal in order to actuate this functionality (I think humvees are like this).

I've not heard of any hacks for this feature, would be nice but all I've heard of for the SG are add-ons like DCCD, front and rear diff lock kits and 4WD on-demand: 4WD On Demand From 4EAT

Super interesting stuff at first glance. Although from what I can tell I've never had issues with the center differential failing to "lock" or fully engage the rear driveshaft. I've never been in a situation where just the front wheel(s) were spinning and the center diff failed to deliver enough power to the rear. Also Ive read that putting the gear selector in 1 or 2 causes the center differential to effectively lock on demand.

Yes, but at 75% throttle

Yes, but at 75% throttle

Meaning it will only fully engage at or above 75% throttle?

Yes, which is why the 4WD on Demand mod was created as per the previous link
