Thread: Remapping New PUMA

Almost forgot...

3 minutes to swap either way with the original and modified Map.

Warning from Pete...Never, ever let anyone do a diagnostic read on your car with the modified Map loaded.

98% of the time nothing will happen, but any "fix" can fall in the 2% that will lock you out on the ECU and a locked ECU is cactus!

Just wondering if anyone wants to comment on the Defender's workshop manual stating that the maximum input torque for the MT82 manual transmission is 360Nm?

Designers usually don't write these type of figures for no reason, Id be interested to see what you all think, especially those who have already re-mapped their machines!

Here it is- a whopping 42% more torque and 25% more power

Here is the two Dyno reports one from the first increase he did and the most current.

Dave,

While the Getrag MT-82 gearbox is far from perfect, it is still the same gearbox used in the Ford Mustang (5.0L V8) producing 530Nm as well as the supercharged version (5.4L V8) producing 690 Nm.

With a 2.4 Defender in standard map claimed to produce 359Nm (according to the Land Rover manual one short of the absolute maximum) and the modified map with a rumoured 42% increase taking you to 510Nm (unlikely, but I'm not going to argue). That still leaves you 20Nm short of the mid range Mustang and a whopping 180Nm on his big brother.

Most people do however know about Ford's issues with some of the Getrag gearboxes, but there is enough of them completely trouble free for them to have ruled out the torque put into them. (Though I'll put that down before the post gets flooded with links from moaning mustang owners!)

Land Rover will never, ever, ever put on paper that their choice of gearbox is capable of handling more torque. Having said that though, there has been enough posts from guys having difficulty with the early Puma fitted MT-82's.

The Land Rover manual is not a "classified" document and its there for anyone to read. If you really believe everything they write in there (indemnity and protection against claims and law suits), it becomes the same as believing everything you read in the news papers...

Cheers,

Hey guys, has there been any new progress in the realm of remapping the Defender 2.2L engine? Has BAS managed to set up an email remapping service similar to what is available for the 2.4L?

Also, why in hell did Land Rover decide to put these motors in the Defender, when they have the TDV6 available?

Can anyone tell me about engine reliabilty and longevity with these remaps?

I'm thinking of doing a inter cooler, exhaust and Bruce Davis remap on my 2.2 110.

Does "limp mode" protect the engine if something in the tune is out?
In other words if the engine sensors pick up pinging or starts to over heat etc does the limp mode kick in and protect the engine from blowing?
