Hi Halfpint,
Yes it comes with a list of curves broken down into 4 sections of 4 curves and on a separate page there is a list of what curve is standard for every Mini engine, even by engine number prefix for some.
I thought the same about electronic ignitions, no points to burn out or close up, that and the cost is why i bought the el cheapo Chinese one. The difference between the Chinese one and the 123 is night and day. I just wish they weren't so bloody expensive!
