This information is not well documented. This is normally used to either compare a potentially malfunctioning distributor, or to have a new one curved to match this profile. When you buy a new distributor today, such as the Bosch “002” unit to replace a defective 008 or 013 unit originally installed in the Tii engines, this curve is not present.

If you want your car’s distributor to perform exactly to OEM specifications, have a qualified technician perform this work. We recommend Precision Auto Research in the USA for this type of work. They have been doing it for many years.
