Which Part Number For Replacement ECU?

DaveDaft · Jan 11, 2017

It's looking like I'm going to need to replace the ECU on my Landy. It's a 110 Defender, TD5, year 2000.
As far as I can tell (after a bit of Googling) the parts number for the old ECU is MSB000080. I spoke to a parts company this afternoon and they were telling me the the newer version, NNN000120 can be 'flashed' and fitted.
But I read on a Landy forum that this isn't true, Can anyone shed some light on this for me, please?

You can fit the later type ECU but I believe you have to code the injectors and such.

The newer ECU is better as it gives the ability to read faults via a nanocom etc..

Thanks for the reply.
Do you have any idea how much it will cost to code the injectors etc?

Honestly I couldnt tell you, all I know is you can do it yourself with a Nanocom

@sierrafery , Can you give some guidance to @DaveDaft please.

One thing to be aware of is that the NNN are more expensive.

@raywin may also have some info on this.

Cheers

I recently had some problems and I discovered that the TD5 engine with the 15p serial number uses the later NNN000120 ECU which can be flash programmed with a new map, mine has this and was one of the first it was registered in November 2001.
These are also on the discovery 15P engines with manual transmission
The Disco TD5 15P with auto transmission has a different ECU

The 10P S/N engines use the older type MSB000080 ECU this cannot be re mapped, but I think there are people who will program an eprom and use this to program the ECU by soldering it onto the board in place of the original.
I believe this ECU has the standard 10P map in it.
As far as I understand both can be read by Nanocom but not by standard OBD2 readers as the configuration is non standard.
Now I am not sure and it will be best to verify but I think the newer ECU can be fitted on the older engine,

sorry one point I missed is that if you use a disco ECU on a Defender the temp gauge works backwards and there are some throttle pedal issues,

DaveDaft · Jan 11, 2017

Ah, ok. Thanks for that..

Hope it helps, it's just what I read when I thought my ECU was up the spout.
Some info here worth a look.

I think Gary at Alive Tuning often has ECUs for sale.
