FAQ

What does a tachometer adapter do?
A tach adapter converts or amplifies your engine’s RPM signal to a format your tachometer can read—especially useful when upgrading to aftermarket ignition systems, adding a digital gauge, or doing an engine swap.

When do I need a tachometer adapter?
You may need one when changing ignition types (e.g., from points to electronic), using an LS or COP (coil-on-plug) ignition, installing an aftermarket ECU, or connecting a tach to a vehicle with no standard RPM output.

Are these adapters universal or model-specific?
We stock both! Universal adapters work with most aftermarket and OE tachs, while certain modules are tailored for LS swaps or specific ignition/ECU setups. Always check compatibility before purchase.

Is installation difficult?
Most adapters are designed for straightforward wiring with included instructions—usually connecting to the tach signal, power, and ground. Plug-and-play models may use factory connectors.

Will your adapters work with both analog and digital tachometers?
Yes—just verify that the adapter’s output matches your gauge’s input requirements (e.g., 12V pulse, voltage range, or divided signal for cylinder count).

What if my tach reads double or half the real RPM?
That’s a common sign you need a signal divider or multiplier. Many adapters allow you to set up for 4-, 6-, or 8-cylinder operation and correct the output pulse.

Do your adapters require calibration?
Some have DIP switches or programming steps to fine-tune for cylinder count and ignition type. Instructions are provided for exact setup.

What if my adapter doesn’t work or isn’t compatible?
Customer satisfaction is our priority. If your adapter doesn’t perform or fit your gauge/ignition combo, contact us within 7 days for a prompt replacement, exchange, or refund.
