Ignition System Tach Adapter, for D.I.S Ignition Kits

Ignition System Tach Adapter for Compu-fire D.I.S. Kits

Upgrading your vintage air-cooled Volkswagen to a Compu-fire Distributorless Ignition System (D.I.S.) is one of the most significant performance and reliability enhancements you can make. However, this modern leap in technology often leaves traditional tachometers in the dark. Because the D.I.S. eliminates the standard distributor and uses a waste-spark coil pack, there is no longer a single primary ignition pulse for your tachometer to read. This Compu-fire Tach Adapter (Part Number 00-9426-0) is the essential bridge between your high-tech ignition and your dashboard instrumentation. It is specifically engineered to sense the firing pulses from the D.I.S. module and convert them into a clean, stable square-wave signal that standard 4-cylinder tachometers can interpret with precision accuracy.

Constructed with the legendary quality associated with Pertronix and Compu-fire, this adapter ensures that you don''t have to sacrifice your engine monitoring for the sake of ignition performance. Whether you are running a high-revving street engine or a rugged off-road sand rail, knowing your exact RPM is critical for tuning and engine safety. This compact, potted module is designed to withstand the vibrations and harsh environments of an air-cooled engine bay. By integrating seamlessly with Compu-fire kits 9419 and 9420, it provides a plug-and-play solution that maintains the vintage aesthetic of your interior while utilizing the most advanced spark delivery system available for the Type 1, Type 2, and Type 3 platforms.
