Now I remember why I switched to the Grid, WAY more user friendly. Anyway here is a video, you would have start with however much advance you want to begin with and enter retards from there. With a grid you just ad to the base on the scree and don't have to touch the distributor/crank trigger. In the 31 you will have to add the timing to the distributor/crank trigger and subtract from there
