Our leveller device is in the first on the market that is truly plug and play.
 
These are used in E series N57 BMW build when you are pushing over 500hp. 
 
The EDC17CP09 DDE that is used in the E series N57 cars uses a 3v system whereas the later DDEs use a 5v system. This clever little device allows the DDE to be tuned to the full capabilities of the fuel rail pressure sesnor that many use from a 50d N57.
 
These levellers are sent out with instructions for installation and it is paramount that the vehicle isn't started until tuning has been carried out!
