It seems to me like the Yoshimura EFI adjuster may be the better solution to the mapping problem of individual varience and not being able to download maps for individual motorcycles. This little device is typically provided by your serviceman and used in conjunction with an exhaust analyser to adjust fuel injection for any pipe or motorcycle. It doesn't advance spark timing, but hay, you don't have to use premium gas! It only costs $60 to have it done, instead of $300 for the PCII.
