Title: Retrofit Traction Control??
Post by: smo on April 25, 2006, 12:31:27

Sadly my 90 doesnt have traction control....is it possible to retrofit E.T.C onto it or is it impossible or stupidly expensive?

Because i want traction control and not lockers. TCS/ETC doesnt break CV's, shafts or anything else like lockers can easily do.....

As the ETC uses the ABS, I'd guess that it would be a tad expensive as you would need the ABS modulator, ABS hubs/sensors/wiring, and probably some ECU as well !

Hmm, shame....

Anyone got ideas of cost though out of interest?

The only cost effective way would be to buy two ABS/ETC axles of late Defender and then it's just an ecu and electronics job. So if you really want to do this then look around for a wrecked Defender with good axles that have ABS and ETC

btw ETC can still breaks stuff - just not as much as front lockers maybe but it happens.

After 5 years of off-roading with ABS/ETC is also has advantages and drawbacks. Low speed cross axles, like cross a ditch will catch the system out  as you need a good bit of rotaional difference for the ETC to kick in. Slippery ascents and side slopes can have you sliding back and forth as the power gets transfered back and forth between the wheels on an axle etc etc.

Cheers

Looks like a no go then if its an axle change jobbie :(

Why didnt they tick that box when ordering i dont know - they had every other extra possible :p

I might consider some True-Trac LSD's instead then :)

Smo, traction control works by trying to clamp the brake on the spinning wheel, talk about shock loading, lots of possibility to upset 1/2 shafts and cv's.  The ARB's spread the strain across both 1/2 shafts and cv's, and should be engaged before wheels start to spin, so in some effect give the transmission an easier time, unless you go berserk....

Limited slip is probably easiest on the shafts of all. For the cost, Id go for ARB's, slip em in before you get stuck, dawdle over the rough stuff, then disengage em.

Perfect
