Has anyone installed a CDL on a DII and wondered what exactly it changed?? I have!

When I engage the CDL with the engine running, I have the CDL and the ETC working together. I have noticed that the ETC doesn't activate as frequently when CDL is engaged. I guess my question is; what exactly is the CDL doing? I know it distributes power evenly to front and rear axles (right?), what does the ETC do to compliment it? What types of situations might I encounter where I'll be glad to have both available or simply working together? Would some situations call for de-activating CDL or ETC?

Engaging the CDL causes the power from your x-fer case to be split equally (50 front-50 rear) between the front and rear axles. This will prevent power loss to an axle if the other axle looses traction. You are basically locking the diff in your x-fer case. If you engage it prior to starting the vehicle, the computer will sense that it is locked and will disable the ABS/ETC. Once engaged, the ETC still works from side-to-side, but doesn't have to worry about comparing front-to-rear wheel speeds since they are "locked". My experiances have shown a great benefit when backing down steep inclines, ascebding loose dirt inclines, and just overall off-raod capability has been increased. Best mod I've done yet.
