Thread: Traction Control / CDL

Yes the most benefit is on very slippery flat ground or flat axle twisters, but it works well up hill too. Cheers

I bought one for my D2,ended up selling it before installing(it went with the D2).I really enjoyed the CDL and TC,it went well.The trick as mentioned is dont use excessive throttle.

I would disagree. The TC in the D2's more aggressive than the D2a's and combined with CDL, well it rocks. In sand, under hard power with an uneven surface, yes it can rob you of accelleration, but its a simple proposition to restart the car and have TC disabled. Have competed against locked other brands and, again, it is spectacularly competent.

Agreed Nick. Cheers

Hi Andy, I didnt fit the working CDL and as far as I know it came on the car from Landrover on production. unless someone fitted it prior to me owning it, in which case they have done a great job.

I have read lots about some having Linkage installed, and some not- Did The D2s that came with no linkage still have the 4 position lever for engaging different 4x4 modes installed?

No rectangular headlight D2 had CDL activation as standard (quite a few had the centre diff internals though). If you are able to turn the vehicle off whilst the CDL is engaged and then restart with TC lights etc on, then its retrofit/retro activation of the CDL without the wire cut to the SLABS ecu to make the thing function correctly - ie a D2a does not have the ability to run CDL locked with traction control not working - they must both run together on that model or it can run without CDL locked and traction control only.

Cheers

Some people on here insist that the D2a had it right, but in truth you want max aggression on the ETC to assist in transferring drive. The ETC on the D2 was very aggressive in low range as it had no CDL...now add CDL and you get max same axle aggression and both axles sharing the same torque. Presto! Why you would want to dumb this down is beyond me. If you need more momentum use more right foot. I am able to get good momentum and acceleration in sand when required, and still have ETC chattering away giving some assistance in the background...certainly not hindering progress.

I love it when the answer is simple! thanks Oz.
Someone must have done it before me. handy to know!

On my 2002 D2 that had no internals, TC was aggressive and appeared to work well. After selling the car and fitting the centre diff lock to the transfer box and connecting the switch to the ECU so it knows when CDL is operating.
Now when low range and CDL is engaged two lights are illuminated on the dash and the TC aggressiveness is reduced as it should be when CDL is engaged.
The car is much better with CDL and will dig holes with two wheels when required.
