Thread: Puma software patch out

So is it a new new patch?

or is it the old patch that a few dealers seem to be unaware of the quarantine....

or is it the old patch that is now out of quarantine?

???

the pumas got electronically controlled injectors, simliar in concept of operation to the TD5.

The computer makes the injectors fire at the right time and for the right duration to inject the amount of fuel required to make power.

The puma engine was remapped to suit its intended role in the deefer as opposed to the transit van

During this remapping some mechanical limitations of the engine were uncovered (similar ocourances occoured in the transit van and the td5 as well) and the software that controls everything was updated. due to other changes in production and other requirements (differing fuel qualities and power output regulations as examples) some maps if applied to some engines produced undesirable results.

Those patches were marked as not to be used (quarentined).

the question dullbirds aiming at is is the update you are getting

1. the old quarentined patch that has been fixed
2. the old quarentined patch thats hasnt been fixed and probabley shouldnt be installed
3. some new patch.


having a WAG...

bet they've wound the injection advance back a little at low/cold engine speeds (and assuming the ford injector is capable of multi stage injection) remade the Prime spacing as well as potentially putting in a touch of post completion injection to give the tail end of the combustion process a temp boost helping out with winding the turbo up and heating the engine.

I can't really understand this but this is probably what pats suggestion to me was a while back as to what was causing our issue....(I think)

It's just like your computer... The engineers who wrote the software realised they stuffed up, and you have to install a fix to get everything to run properly.

If cars get anymore like computers they will crash repeatedly without warning, and you will need to shut them down, get out, give them a good kicking (booting), then start them back up again...

I wasn't talking about not understanding that...of course I understand that doesn't everyone that owns a windows computer......

actually doesn't anyone that actually owns anything gadgetry understand that.

I was talking in regards to daves explanation of what he thinks it is...I'm sure its what pat has been saying all along how ever dave explained a tad different but probably only with the words he has used

"Hello, this is Land Rover customer support, have you tried switching it off and back on again?"

I'm taking my 110 into the dealers tomorrow for a couple of issues, I'll ask if they have a new update available. By the way you only get so many updates, from the Land Rover GTR:

A 'flash' EEPROM (electrically erasable programmable read only
memory) allows the ECM (engine control module) to be externally configured, using the Land Rover recommended
diagnostic tool, with market specific or new tune information up to 14 times. If a fifteenth update is required the ECM
(engine control module) must be replaced.

Cheers,

Tim

Interesting cheers for the info Tim....I wonder whether this effects the people that have the equipment to change there maps on there cars? or because they are undetected (or so I'm lead to believe) that's not the case.....
