Universal Tach Convertor Magnetos

The Universal Tach Convertor Magnetos from MSD Ignition bridges the critical gap between magneto ignition systems and modern tachometer instrumentation. Built for enthusiasts restoring classic vehicles or upgrading vintage ignition platforms, this adapter converts magneto trigger signals into tachometer-compatible output without compromising ignition integrity. Whether you're retrofitting a hot rod with period-correct magneto ignition or integrating aftermarket electronics into a restoration project, this tach converter eliminates the guesswork of signal compatibility.

This compact adapter (measuring 3.3 x 2.3 x 5.7 inches and weighing just 0.35 lbs) is engineered specifically for MSD Pro Mag magneto systems, translating high-voltage magneto outputs into clean, linear tachometer input signals. The converter handles the signal conditioning internally, preventing false tach readings caused by magneto's unique firing characteristics. Its lightweight construction and minimal footprint allow installation in tight engine compartments without sacrificing reliability, making it ideal for cramped vintage engine bays where space is at a premium.

Mechanics and engine builders working with MSD Pro Mag systems benefit most from this converter when accurate RPM feedback is essential—whether tuning carburetors, optimizing ignition timing, or diagnosing drivability issues on magneto-equipped engines. Installation is straightforward, connecting between the magneto output and any standard tachometer input. This adapter is particularly valuable for street rods, vintage race vehicles, and restoration projects where factory tach compatibility wasn't originally designed into the magneto platform.
