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+.

Please note: the distributor is supplied without a gear, you must transfer this yourself.

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.

Funktioniert top.

Ich habe nach Beratung durch Leen diesen Verteiler gekauft. Die CCW Version ist geeignet für BMW m10 Motoren mit linksdrehendem Verteiler. Es gibt auch keine Probleme bei mir mit der vorhandenen TSZ-I Zündung. Das vorhandene Zündsteuergerät, welches eigentlich nur ein elektronischer Unterbrecher ist, muss abgesteckt werden. Es wird dann nicht mehr benötigt. Passende Zündspule sollte man gleich mit dazukaufen.
Bluetooth und die App funktionieren auch einwandfrei, allerdings muss man sein Smartphone immer aktuell halten, sonst kann es zu Verbindungsproblemen kommen. Nach dem neuesten Android Update ist alles kein Problem mehr.
Über die App kann man dann mit anderen Usern seine Kurven austauschen. Sony Xperia Xz3 mit Android 10. Insgesamt also eine super Lösung.
