Thread: TD5 ECU Identification

The following information from ECU/Software Module Information System
(look under Diesel EMS - Lucas TD5 Landrover)

ECU VARIATIONS
Although looking and functioning identically there are in fact two distinctively different ECU types which have some different diagnostic capabilities. The first and therefore earlier type is referred to as the non flash programmable type. This was replaced in late 2002 with a flash programmable type. Non flash types have part numbers that start with MSB while Flash types start with NNN


Non flash programmable type ECUs typically have just one vehicle types maps pre-programmed into them by the factory. This means they only have one Vehicle variant / fuel tune code and cannot be set to any other. Sometimes however, they might have more than one code stored inside an ECU or the ability to switch between multiple options for a given type. We believe that up to 6 could be pre installed at the same time. If an ECU does have more than one code pre programmed into it can be told which code to use by changing the code to the one for the configuration that you want. Of course, you need to know what any other codes are that may be installed and then try them in the ECU to see if it changes, meaning it has that map installed. Sometimes the sticker affixed to the edge of the ECU itself, which bears the part number, also shows which vehicle types the ECU can be configured to. But if not, fortunately the code can only be one of a handful and can even be deduced to some degree using the information supplied here as a guide.
Flash programmable type ECUs have the added ability to have their Vehicle Variation and fuel tune maps re programmed diagnostically, which is available as a separate capability in SM201. They also have an incremental programming history memory which includes information such as the VIN number, date of programming and an assembly number which identifies what an ECU was programmed with.

Although part number information has been provided to help identify which type an ECU is, the easiest way to tell is simply to connect to the ECU and read the programming history. Non flash type ECU's will not support the function and flash types will show you the history including the VIN number.

(My 2002 Disco TD5 with auto transmission has a NNW500140 ECU fitted)

Hope this helps.

I have a NNN500030 in my '99 auto - different ecu for auto/manual

I have a 500020 in my 01 Manual, previous to this was the MSB ECU for early models.

Nanocom have a Map Wizard which will generate a Map File.

There is a list of ECU's or more particular the map file for the different models around the world.

There are no listings for the MSB ECU's. There is no listing for the ECU that you think is best.

So grab yourself a Nanocom or get access to one.

Nanocom cant change anything on an MSB ecu.
Need to have the NNN ecu.Yes you can change the ECUs over from MSB to NNN.

Heres one list,
ECU identification - LR4x4 - The Land Rover Forum

heres another which raises the issue of whether later ECUs can be used with 99 td5 (cant see why not)
Web Rover

if the nnn500030 works, that might be the one to go for,

THX for ALL yr replies

NNN000130
NNN500030

Will do you just fine....

Have you got the right gear to play?
When you say play, you looking to write your own maps?

First up, a nod to the gold TD5 parked at the Brindabella Medical centre on Friday. More electrics than the space shuttle

Aaah, a wayward number in my quote, thanks for that.
Im currently sourcing a Nanocom, but everyone I contact is out.
So far the best place has been
Mail Order 4x4 NANOCOM TD5 Discovery 2 Diagnostic Tools
Im waiting an email from them but they're probably out too. Best price Ive found though, half that of the Aussie shops.
As for play, I mean just that. Check out the engine and see what's what, but also explore the mapping. I dont think I have enough nous or time to master mapping.
Although I do know of a VERY nice guy in Whyalla who aparently does brilliant maps
Once I get a decent ecu, that plus a nanocom means I can learn a bit more, but also get new maps once my circumstances (time, money, mods) change
