What does it mean MARRYING  a VIRGIN ECU and EIS? The ME (ECU=Engine Control Unit)  and  EIS (Electronic Ignition System) control module are electronically permanently married to each other after 40 engine starts. There is no factory procedure to undo this. This means that a used engine EIS or DAS control unit cannot be used on another vehicle. A new control unit can be installed for testing provided the 40 engine starts are not exceeded. Note that the new control unit must be variant coded before it can be used. If the 40 engine start cycles are not completed successfully resetting the counter to 0 (removing the version coding) is possible if  you disconnect the power from the ECU for at least 45 minutes.
