Distributorless LS RPM Adapter for Any Tachometer

Achieve precise RPM readings on distributorless LS engines with the Tach Adapter's signal conversion for both factory and aftermarket tachometers including shift lights. Engineered for simple installation without an extra harness, it supports LS1, LS2, LS3, LS6, LS7, LSA, L92, L93 and L99 families and its durable construction delivers dependable performance under demanding conditions.

LS Engine Tach Adapter for GM Tachometer Compatibility

Retaining a factory tachometer during an LS engine swap often results in erratic readings because the ignition coil pulses lack the square wave input that standard gauges expect. The Tach Adapter achieves this with an internal circuit that translates distributorless ignition pulses into a stable square wave output for reliable tachometer readings. Because no dedicated harness is required, installers can route wires behind the dash or firewall for a tidy cabin layout, and broad LS1 through L99 engine support means one adapter covers virtually every GM small block without the need for different parts per model.

Advanced Signal Conversion for Distributorless Ignition

The Tach Adapter's internal circuit captures variable ignition coil pulses and transforms them into a precise square wave that standard tachometers can read without error. By reshaping each spark pulse into a consistent frequency, it prevents misreadings that often lead to overrevving or false shift light activation. This level of accuracy is vital for maintaining engine health and keeping performance thresholds clear under rapid throttle changes. Consistent rpm feedback helps drivers and tuners fine tune shift points and monitor engine stress in real time.

Standalone Installation for Uncluttered Wiring

Designed to operate without a pre-attached engine harness, this adapter gives installers full control over wire length and routing. Wires can be tucked behind the dash or routed through the firewall for a neat dash bay and minimized wear points. Eliminating excess cable loops speeds up installation and reduces the risk of chafing in tight engine compartments. This clean approach also simplifies future maintenance by keeping critical wiring paths visible and accessible.

Universal Fit Across LS Engine Families

Coverage from LS1 through L99 means one adapter handles popular variants like LS2, LS3, LS7, and more without requiring model specific parts. This universality reduces the need to stock multiple adapters and cuts down trial and error during part selection. Shops and enthusiasts gain a predictable outcome from project to project, which accelerates the swap process and trims overall build time. A single part number lets you focus on tuning instead of fitment questions.

Robust Construction Ensures Consistent Performance

Built with durable components, the Tach Adapter withstands heat, vibration, and constant duty cycles commonly encountered in engine swap applications. Its rugged housing protects the sensitive electronics that shape the ignition pulses, preventing signal degradation over time. This reliability keeps the unit operating consistently from daily driving to track abuse. Installing a device that endures in harsh environments means stable tach readings for miles on end.

Engineered for precise fit and lasting reliability in any LS swap project.
