Tracy already has a timing advance feature (mode 6), that can be used as a timing retard of 4 degrees at whatever MAP setting you want. I'm not sure that's enough change though. If there's going to be a new feature, why not make something more along the lines of a significant timing retard that happens at a set MAP. This would stop detonation, as well as notify you via reduced power that you had crossed the line.
