Part numbers for Defender ECUs

Hi

Can anyone provide a definitive list of ECUs that are specific to the Defender or can be fitted to the Defender without issues.

Someone is hoping to buy an engine from me but its out of a Discovery. My understanding is that he needs a Defender MSB ECU. Rather than a Discovery unit.

Also, I have read that the Defender ECU is under the drivers seat. Has anyone had success in fitting it in the engine compartment?

I put everything from under the seat between my seats on the bulkhead. Only the diff lock sensor cable has to be extended.

There are 2 versions off the engine ECU the old and the 'new' I believe there is no technical difference between the disco and Defender it's just the software. Roel

1984 90 2.5 na Diesel - RR V8 (1994-2001)
1997 Camel Trophy Discovery 300TDI (2001-2009)
2005 G4 Discovery III 4.4 V8 (2008-2018) It's gone but it still hurts.
2003 90 Td5 (2009-now)

It depends on whether you have a 10p or 15p engine, and whether it’s an auto or manual. The ECU needs to match the engine but if you try to put, say, an auto Disco engine into a manual Defender you will need to change the ECU and have it coded to the Td5 injectors. There is loads on this if you Google it. Replacement ECUs are getting more and more expensive - perhaps up to £250 right now. You may be able to get some success if you talk to one of the site sponsors such as Gareth at Empire Tuning.
