Yes, the idea crossed my mind, but there was no request for it.
And also some text are shorter, but the main problem is when they are longer than the ones stored.
You have to relocate a lot of data and this is a laborious job, not to mention the risk of messing things up.

For petrol (gasoline) use/try data file AH52-14C088-DD.
So the set of files will be:
SBL: 6H52-14C025-AA
EXE: AH52-14C026-AD <- this one is replaced
DAT: AH52-14C088-DD

I do this and everything work now - tachometer work right! Thank you Alex!

Sorry for the stupid question, but how to enter engineering mode on SDD software? Will it ask for a password?

Yes, normally it does.
But there is an workaround way, by launching softwaredownload.htm from the \Program Files\JLR\IDS\Runtime\ folder.
Don't get me wrong, but if you have no experience with flashing, better don't do it... You can mess things up... Do it at your own risk! Don't hold me responsible if something will go wrong.

Below are the steps that can be used for flashing modules with SDD.
It's a workaround solution that's allowing you to flash whichever module you want with whichever firmware you want.
So it's a very powerful and in the same time dangerous procedure if not done properly, because there are no foolproof checks.
Meaning you should know exactly what you do, what you program/flash and where and in which conditions.
Two important things are:
1. You must have a battery conditioner connected when you do it to maintain at least 12.6V on the system
2. The engine must be OFF.
Again, be very, very, very, very careful with this stuff....

And another thing:
The instruments are one of the few, if not the only one ECU on the car, that, sometimes (not always), gives an error when trying to erase the internal flash.
Meaning it timeouts when calling the erase flash functions. But the erase is done OK. Only the response/confirmation is not sent back from the cluster.
The SDD don't know how to handle this and throws a timeout error. And, of course, it stops the process and you'll have a "blank" flash and the car will be immobilized.
Don't panic, try again and it will work.

Double click on softwaredownload.htm in the folder \Program Files\JLR\IDS\Runtime\

Select Land Rover, enter VIN and press OK

I seem to have a problem with the engineering mode on my SDD.

I can go all the way along but it stops at the "Have (a lot of) patience when the whole firmware database is read." bit

I don't see anything more apart from the top line.

It sat for over an hour and nothing happened, see below

Yes, you can through that one too.

First you need to run the procedure to see which files the SDD is using/choosing when it updates the software.
It will choose the ones fit for your cluster.
Then you need to replace those files with the modified ones. Both EXE and DATA.
Of course, you rename the modified ones with the names of the ones that SDD is using/choosing in the above step. You'll keep/move the original ones for safety.
Then run the process again.
I hope that I made myself understood...

Don't forget to make a backup at each step.

Alex, thank you for the great tutorial.
By now I´m trying to learn as much as I can. I will not try to flash anything by now because I know it is risky.
Regards.

I'm not having much luck here.

Tried the method as per my last pic, but it brought up a message "not available" or something like that, I forgot to take a screenshot.

So I guess the last option is go in to the SDD, make a diagnostic session and try to reflash the IC through the extras and take note of which files are chosen there... 2008 Freelander 2 HSE Si6 Black/Black - Hers

New version posted on first message.
A new item was added to the on-board computer.
After the average speed, you'll have now Battery Voltage.

The battery voltage is computed by the instrument according to its power supply.
So any discrepancies are because of the internal algorithms and ADC error.
Anyway it's a nice item to have because you can see now how the body controller, through the engine ECU, is adjusting the charging voltage based on ambient temperature. And, of course, at startup, until you crank the engine, you know how good or bad the battery is.

Additional item: instant speed.
Now the on-board computer has the following items:

1. Trip
2. Range
3. Average consumption
4. Instant consumption
5. Average speed
6. Instant speed
7. Battery voltage

It seems that I am coming up with an item per 24h...
I will take a break for now... I'm out of ideas...

This is C.O.O.L Alex.. indeeeeeed it is. I was hopin that i could use your files to flash my fathers fl2, but I do not think he will ever enjoy this new functions. but on the other hand. I with my D3 would love to have this mod on my car. Flashing a fl2 ipac with a D3 Ipac will not end good. Is is hopless to do this with a d3?

Mr.P

Hi Alex. I am Greg777 from Russian lr-club.com. Sorry for a little inconvenience on our "severe rules" forum. Forum rules require duplicate of all messages on Russian. Do not hesitate to do it formally on Google, we'll still read the English version) Your posts always very interesting and useful for us, you know. Thank you for your job one more time.
PS You also can contact me any time for russian translation, if you want.

Thank you very much for your kind words!

I've tried to contact him to try to explain, but I wasn't able to do it, not even to access the mailing system.

Who knows, maybe I've touched a sensible chord...
It won't be the first time when a forum gets sponsored by a certain category of people/traders that don't see with good eyes the free information's circulation, if you know what I mean...
If the cluster topic could bring them new clients, this last one, opening many's eyes, diminishes the number of their clients.

Well, if that's supposed to be, so be it...
We have a saying: the dogs bark, but the caravan goes on...
Us to be healthy, as there are plenty of things to discover!

Hi Alex!
Very good mods! Congratulations.
In special the battery voltage. It would be very usefull for me.
It´s a pity that I don´t have courage to flash my car with it. If anything goes wrong and I need help here in Brazil we have a very bad, slow and expensive service for Land Rover brand. So I prefers not to risk by now.
Maybe later if I get more familiar with SDD software.
With your knowledge you can get any information from canbus network and display it?

Regards,
Andre.
