Brake-Throttle Modulation (BTM) only works on certain types of LSDs (Torsen, etc). It's the primary method for maintaining traction in the military HMMWV (which uses Torsen diffs), and will allow a skilled driver to get over/through obstacles that would usually require a locker. Not gonna happen with an open diff.

 

Yep. Did some more research here. An open diff always applies equal torque to both axle shafts. Applying the brakes does nothing but add to the axle load - equally. It will not force more torque to the traction wheel.

 

I tried this last night as i was stuck in the snow and it does not work

 

You will need individual e-brake for the rear wheels, if one is spinning, use the e-brake for that wheel, so power can be sent to the other wheel.

 

Yes you can, have done it a bunch times, it makes the traction differance less as far as the diff is concerned and helps put power to the ground. 4low with really pushing hard on the peddle can really help you climb/get out of situations.

 

pull and hold the park brake release and slowly apply the parking brake. this will force power to the wheel with traction. takes some practice but has worked for me many times.

 

I'vee done it wgen stuck in the snow. Gas+Brake+Gas+brake = might get unstuck

 

A winch works nice to get un stuck
