I just noticed that http://www.evoms.com are cloning your original ECU so you can 2x ECU and one which can be used for mods and swapped over back to the original.

They only offer this with BOSH.
Does anyone know if it can be done with the new Siemens ECU N/A Cars or someone that can do this?

 

Anyone know, I have a European car so it needs a ZZZ Programmed ECU...
