Ignition maps are something that are quite hard to secure, it doesn't help that most of the information is probably in Japanese.
I've been trying to think of ways to get that information out, and besides from reverse engineering a PGM, the easiest method I thought of was to simulate a running bike and interpolate results........this has been in my head for atleast two years now but I haven't been able to set up the facilities to do all this yet.
