The 123 Ignition Programmable Distributor TUNE+-4-R-V-V-EXT-BLUE  with Anti-Theft is a high-quality ignition system designed for Volkswagen VW T2/BUS air-cooled engines, where the engine is located at the back, under a metal cover. This creates a kind of Faraday cage; electromagnetic radiation is blocked (both ways). What this means for the TUNE+ is that the Bluetooth connection falters at best, and does not work at worst. The 123/TUNE+ 4-R-V-EXT-BLUE completely eliminates this problem; the external Bluetooth module is mounted outside the engine compartment, to provide an always reliable Bluetooth connection. 

This distributor is an excellent upgrade for classic VWs and provides improved performance, reliability, and security.

The TUNE+-4-R-V-V-EXT-BLUE distributor is easy to install and requires no modifications to your engine or wiring. The distributor fits perfectly into your VW engine and comes with a detailed instruction manual that makes installation a breeze. You can easily adjust your ignition timing to optimize your engine's performance. The distributor features a built-in microprocessor that allows you to program the ignition curve with precision, ensuring smooth acceleration, increased power, and improved fuel efficiency.

A fully programmable ignition curve, adjustable from your iOS or Android phone, via Bluetooth, using the 123 Tune app. Main features of the TUNE+ EXT-BLUE distributor include rev counter, anti-theft system with a PIN code, Bluetooth, real time tuning, vacuum advance, boost retard, & soft rev limiter.
