I have an ~early 90s mini with an A+ 1275 engine. It has had a 123ignition distributor since I got it. I thought these allowed you to select between a number of preprogrammed ignition maps. However I can't find the selector on mine. In all of the photos and documentation I've seen it's under an allen plug on the side. Are there some that come with only one map and are not adjustable? I don't see any like that for mini listed on 123ignition's website.
The only markings I see on it are "MINI >>--->18-05-12" and "123ignition.nl -BOB=BLACK +6/+12v=RED"
Here are photos of it:
