Disco 2 map

Hi
I have a 2003 Disco 2 with a remap and tried copying the map with a Nanocom 1 and installing it on my new 2004.
It installs fine and drives just like the other one but creates a list of fault codes which i can't clear.
Load back the original map and all is fine. I'm now back with the original / factory map.
Would swapping the brains be a better option. Error codes listed below.

The TD5 ecu contain the following faults:
FAULT 08-01 air conditioning fan drive over temperature LOGGED
FAULT 08-02 fuel pump drive over temperature LOGGED
FAULT 08-03 tacho drive over temperature LOGGED
FAULT 08-04 gearbox/abs drive overtemperature LOGGED

hi there, holy crap batman!
are these two buses on the same engine management systems?
like for like?
be careful you dont bugger it up!!
is it,
(with no offence to your skill level in computer wizardry's,)
worth getting the later car tuned by a pro with a guarantee it won't cause any future problems??

Hi
One is the base spec discovery no aircon, coil springs etc.
The newer one is top spec HSE with all the toys. I thought the map only dealt with engine management, fuel air etc. and another part of the brain with the rest.
All back on original map and no faults now. The plan was always to get a new map for the newer car but i'm waiting to sell the old one, so have computer, will play.

Just be careful you do not brick the ECU playing around with it.

Cheers

Thanks, Thats why I've left it for now
