D3 V's D4 - Off Road

I keep reading that the D4 has superior software to early D3's in the various off road modes which means the vehicle is more capable off road.

My question is if alot of this superior off road ability is due to software upgrades then is it possible to download the new programs into a early D3?

I have on a number of occassions gone out bush bashing with various people from this website and they have proven to me that superior software in serious and tricky off road driving will in 99% of cases work better than more grunt or even lockers.

Mind you the software they use is the old fashioned variety that is programmed between their ears, on the bright side anyone can obtain the same software with experience and practise. ;)

cheers,

True! ......Too true

I'm still interested to find out, that is if anyone knows on here, if a D3 can have the upgrades in the updated off road software that a D4 has installed?

I'm sure other owners of D3's would also like to find out if this is possible.

Hi Terry,

This doesn't answer your question but as the MY10+ Disco & RRS vehicles use a different CANBUS standard, the ecus are not physically compatible. EG, the supension ecu now has the CANBUS wires on a different connector, possibly to prevent incorrect fitment between models. This doesn't guarantee that the software cannot be loaded or wont function if loaded, but increases the liklihood that earlier ecus wont run the later software.

I concur with the others inasmuch as my D4 is much better in sand than my D3. However my D4 has the rear eDiff locker which I'm sure makes a big difference. I have also found that low ratio is better when churning through the soft sand at the beach entry points. Hitting it fast in high often had me bogging down and being forced to reverse out and try again, now I just select Sand in Terrain Response and low ratio and just drive through with minimal slippage and no drama, it's really quite uncanny.
