Does anyone know what the percentage of power transfer per wheel and front to rear is on a '02 Disco II using the traction control? Also, is there a need for a CDL(or front or rear for that matter) when you have this electronic traction control? | ||

Those who wheel on more difficult terrain, myself included, will say yes to the CDL. It compensates for some of the weaknesses of the ETC. By itself ETC is a fine system but there are times when it will fail you. When you get cross axled for example, no help at all, just a whole lotta noise and brake wear. With that said I am glad I have ETC on my rig, at times it feels like cheating. | ||

The more I use my rig off-road, the more I am coming to believe ETC is really only effective in simple slippery situations where you have enough momentum to overcome the braking effect. This past weekend, I had to pull a rig for about a mile up hill in somewhat slippery conditions and after I locked the CDL and stopped and started the truck (to disable ETC), the going went much easier with less strain on the driveline. In another scenario, when climbing a steep hill with a few semi x-axled situations, ETC just couldn't react quickly enough to allow my momentum. After backing down, locking the CDL, disabling ETC, I went right up. Then, there was a little rock fall that I went up with open diffs and ETC and because of the loss of momentum and spinning fronts, I fell off to the right and dragged my right side lower panels across a log for a bit of nasty cosmetic damage. Earlier, with CDL, no ETC, I missed the log just fine. Lesson learned, know your truck. After watching two other rigs (one with rear Detroit one with rear ARB) I think I'd rather have the locker than ETC. | ||

That's BS. That's where it excels. Are you sure you're not thinking CLD? | ||
| Christopher Dynak (Adtoolco) Member Username: Adtoolco Post Number: 116 Registered: 08-2002 |
Yup, I'm sure. It didn't help me at all. I was bottomed out too, so that could have added to failer but I had tires spinning and a whole lotta of clickity-clackity. If I was locked it would have gotten through. | ||

I think traction control sucks in deep, solid sand and/or snow also. It kills your forward momentum and will eat your brakes up quickly. I like having traction control for on-road use, but think it would be better to have the ability to lock the diff's when off-road. | ||

Chris - on firm ground, you can be headed uphill balanced on just two diagonal wheels with the others off the ground, and gently give some gas and walk up on out with the ETC. Of course, when you're looking at slipery mud and being high-centered you're basically fucked anyway, lockers or no. Dean | ||

I haven't been able to turn up too much info on ETC and truetracs in the archives. I'm considering this setup and would like to hear from someone who is using this setup. | ||
| Christopher Dynak (Adtoolco) Member Username: Adtoolco Post Number: 117 Registered: 08-2002 |
Dean, agreed. But in the slippery situation I was in I am sure lockers would have gotten me through. Just one of those rare times I was let down by the ETC. | ||

ETC w/ True-Tracs is an awesome combo. The ETC causes the TT's to be completely automatic and seamless. You have to apply your brakes (which is where the ETC kicks in for you) after wheel-spin for the TT's to lock up. They can then transfer about 75% of the torque to the wheel with the most traction. They are more of a limited slip rather than a full locker like a Detroit. I have an '00 DII with TT up front and Detroit in the rear. | ||

Greg I am assuming you are using the left foot braking tecnique? | ||
| Greg Davis (Gregdavis) Senior Member Username: Gregdavis Post Number: 727 Registered: 08-2002 |
No, that's the beauty. The ETC activates the brakes for you as soon as a wheel spins. The TC light will flicker on for just a second, the TT kicks in, and the TC light goes off. It's a great combo. You never touch the brakes because the computer is doing it for you. | ||

So, if I understand the truetrac will send almost 75% to one wheel...what is the ETC capable of? Also, anyone in the Houston area who has done the CDL install? | ||
| Dr. Joshua C. Gorman (Jgdds) New Member Username: Jgdds Post Number: 9 Registered: 02-2003 |
If you run the truetracs do you have to lock the center diff? | ||
| Greg Davis (Gregdavis) Senior Member Username: Gregdavis Post Number: 731 Registered: 08-2002 |
To get the most from your lockers, a CDL is advised. Otherwise, even though you have ETC, it's not real efficient and you could find yorself with the power going to one axle as opposed to being split equally between the two. If you have the $$ and want serious capability, fing a used x-fer case with the CDL stub. You won't regret it.  | ||

I have a 95 and a 2002. I am of the opinion that ETC is very very good, but there is a real knack to using it, as opposed to it getting away with what it wants. Of course it is not foolproof and I am sure that DCL with it would be a little more positive. What I have found however is that, to no surprise, the D1 has much better articulation and wheel travel, such that I have had occasions where the D11 needed ETC to get through, but with D1 got through the exact same spot WITHOUT the cenre diff locked!. Of course on road the d1 does not handle like the dii and has more rock and roll - funily enough though the rock and roll doesn't offend me after spending a lot of time in the D11 as I first thought it might - thus perhaps the ultimate 'quiet' change for dii would be a 2 inch lift, and an aftermarket ACE system (that you can get in OZ - I assume US also) that would significantly increase articulation off road and aftermarket CDL activater installed. Just my 2c S | ||

I wasn't an ETC believer until 7 feet of snow in three days. Agreed, Scott, there is a knack for using it. I did make it where other part-time 4wd systems couldn't go, including my other vehicle, which could not even follow in the path of the Disco, it just dug itself in. ETC worked really, really well once I got the feel for it, and I'd been driving it on snowy roads since November. For instance, in trying to pull out a stuck vehicle, with ETC, I needed to give a little slack on the snatch strap so that I had some momentum to work with. Trying to start with a slow pull, sometimes resulted in ETC chattering away, but going nowhere. That being said, the ability to lock the center diff, and lockers would give you every possible combination!  | ||

hey guys, thanks for all the input. I was told the '02 DII had a CDL stub on the xfer case but I have looked and did not see it. Does anyone know if this is true and where exactly it is located...I am wanting to do the CDL install talked about on this site. Thanks again | ||

starting with mid year 2001 build II's, they installed transfer cases that no longer have the cdl shaft. i hear that the mechanism inside the case is still there, but the shaft to connect to the stuff inside is no longer there. you can check your build date on the info sticker on the side of drivers side door. |
