Without Norman (on both the Traction and DSuper) as the advance curve is built in and you simply set the correct engine ‘curve’ via a small screw to whichever setting your car requires.
There is a guide included and the distributor normally arrives pre set for a Perfo engine. You may need to select another curve for the 11D but I don’t have the instructions to hand.
I know the setting makes a difference as the one in my DSuper was set to Perfo when I bought the car so had to change it to a DY engine………..
