Thats right, it was meant to to be a modular motor. 4cyl for the Freelander I think it was, 5cyl for the Disco and 6cyl for the Rangie. The 4cyl and 6 cyl were cancelled because after the BMW takeover, BMW already had similar motors in their parts list, and the Td5 survived because BMW didn't have an equivilent for that motor and the 6cyl wouldn't fit into the body.Quote:

So a completely new suite of engines was developed, 4, 5, 6 cylinders with largely interchangeable parts. Then the company was sold to BMW, and the only engine ready to go was the 5 cylinder, which would be the direct replacement for the 300Tdi. BMW did not quite have a direct replacement ready, and so allowed it to continue, but canned further development.
By the time Tata took over the company, and it regained autonomy, the Td5 engine was already outdated, and a completely new design for a whole range of engines - the Ingenium - started development. The Ford engine had been bought in to avoid attempting to upgrade the Td5, which had had all development stopped.
All a bit sad really. I like the TD5. But Euro 6 would have been difficult, to say the least.Quote:

The Ingenium being a Jaguar Land Rover developed engine. mI'm still waiting for the 4L V8!
Reading these articles, I did not know about the different throttle maps for high and low range. I thought the TD5 had become sluggish in Low range, as I had to put the ight foot down so much more!!
In high range the you get a high percentage of power to a low percentage of throttle travel.Quote:

One thing that I found several years ago and was flamed for is that the ECU maps etc were developed by Volvo.
If you run a text program through the standard map every file has a Volvo disclaimer not to change the file.
The suffix used on all the files is also a Ford suffix .vbf unlike the .Map etc used by tuners.
This is a Wordpad opening of the first file of the ECU maps.
I reinforced this just recently as I supplied a standard map to another member .vbf_version = 2.0;

That might be a result of Land Rover being a part of PAG (Ford) at the time your car was built and an EU3 engine?Quote:

You are no doubt correct but I find it interesting that the software should be contracted to another member of teh Ford Group.
I wonder who wrote the original software and whether it was a complete rewrite.
My guess would be Lucas as I have heard comments that the TD5 injection is like petrol car injection rather than diesel.
