123ignition TUNE+ 4-R-V-Škoda (Bluetooth)

123ignition TUNE+ wireless programming

After installing the free app and setting up a Bluetooth connection, you can configure the 123/TUNE+ yourself via your phone or tablet with your own optimal advance curve.

The app makes it possible to modify the ignition curve, display an electronic dashboard and secure your car by means of a start immobilizer.

Model 4-R-V-Škoda

The 123ignition TUNE+ 4-R-V-Škoda is suitable for all Škoda rear-wheel-drive models (sedan and coupé): 105, 120, 125, 130, 136 and 136 RiC, built from August 1983 until the end of production (1990).

In addition, it is highly likely that it also fits models from 1976 to July 1983, as these use a similar distributor. It may also fit the S-series from the early 1970s. In these cases, please carefully compare the dimensions with your original distributor.

Important notes regarding the TUNE+

We recommend that you carefully compare the dimensions of the 123/TUNE+ with those of your original distributor AND read the installation manual carefully before placing your order! The installation manual contains further information about installation and fitting. Based on several examples, it explains step by step how to program the 123/TUNE+.

The TUNE+ works with Apple iOS and Android devices equipped with Bluetooth 4.0.

Coil and spark plugs

Used coils are often no longer in good condition. It is not possible to determine how often a coil has been exposed to overheating in the past. If you purchase a new coil at the same time as your 123 ignition, you can be sure that this coil will no longer overheat. Of course you can also easily order this from us; we recommend the coil shown below.

If you may also need new spark plugs? In this 123ignitionshop we also offer the most commonly used spark plugs for the cars for which 123ignitions are designed. See the spark plug page.
