Please note before ordering the TUNE+

The cogwheel of this TUNE+ 4-R-V-BMW CW 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: 123/TUNE+ 4-R-V-BMW CCW

We strongly advise you to check the dimensions of the 123/TUNE+ with the original distributor cap AND to carefully read the installation manual before you order! In the installation manual you will find more information and a few examples with a step by step explanation on how to install and program the 123/TUNE+.

The TUNE+ will run on all iOS and Android devices with Bluetooth 4.0 (or higher). 

Coil and spark plugs

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. Of course you can also order this here, we recommend the 123 Red Coil.

Perhaps you will also need new spark plugs? At 123ignitionshop we have added the spark plugs most commonly used in addition to the 123ignitions we offer. See: the spark plugs list.

Great product; fairly easy installation

High quality unit which has taken the BMW 2002 world by storm. No more issues with tired springs in 40-year old Bosch distributors. Has a factory look when installed.

I installed one in my 1974 Turbo. A couple of hints: use shrink wrap for the wires for a cleaner installation; and, use an iPad, not an iPhone to program the vacuum curve.

Bye bye timing light, and annoying points.
