The cranking advance is the ignition advance that the MJLJ commands during cranking (i.e. when the RPM is low - about 500rpm). It won't affect the smooth running of your engine. You can see what value it's set by with the RPM at zero - the advance gauge should show the figure

right got yeah, nice one but i thought that you could fine tune the timing up to a few degrees, im not sure if its right as the motor still runs for a few seconds after i switch it off?

The Megajolt operation guide will show you how to set the cranking advance. As spandit alludes, it's only used during cranking- once the engine is at idle it uses the regular ignition map.

If your engine is still running a short while after you turn it off, you want to make sure all power is cut to the ignition system, as it sounds like it might be running until your fuel lines run out of pressure.
