  1. Hi, is there any help to install eManage on a BMW straight six with a Siemens MS40.1 as stock ECU? I am having some troubles on running properly the injectors. I have read that on OBDII cars a resistor box has to be mounted because of the injector low impedance, but I think mine are high impedance so I am lost…


    • Hi Carlos, if you are using a Emanage on your BMW, chances are you will need a converter box to change from low to high impedence. Of course if you pick up a Greddy Ultimate this is solved through a switch on the DIN panel. Sounds like an awesome project, let us know how it turns out!
