AFAIK, it was the post 02 Defenders that had the anti stall fitted as a response to feedback about the Td5's fondness for stalling. No doubt Ian, 'Porny' will be along soon to set me straight! LR did/does actually advocate the no throttle technique for pulling away in the Td5. It does work although nothing like as effective as the 'Puma' versions. I was told by a man at LR that the as soon as you touch the throttle it kills the Td5 anti-stall which explains why it's still easy to stall and anti-stall Td5!
I think it's great technology. I had a Cummins engine truck with anti stall over ten years ago. Great for getting 40-tonnes moving from a standing start on a steep hill.
