Please note: The cogwheel of this TUNE-BMW-4-R-V makes the unit turn Clockwise. When your engine is a M10 of the newer type (as f.e. is used in BMW E21 after 1978) a distributor which turns Counter Clockwise is needed. The electronics in the 123 unit is programmed to function as well in case a cogwheel with a different turning direction has been mounted. An adaption piece needs to be made.

If you don't have a new coil, you should order a new coil. Although used coils all look alike, they should be viewed with suspicion since one cannot tell from the outside whether and how often they were exposed to overheating in the past. Installing the 123ignition system will ensure that the coil will never overheat again in the future. We recommend the Bosch Blue coil.
