TachMatch

TachMatch is a solution for making your tachometer work, when things just don't match up like they did at the factory.

Did you do an engine conversion? Maybe change the type of tachometer drive signal by installing a different ignition? Install an engine with more cylinders? You don't have to change your tachometer or instrument panel - you can install a TachMatch into your car, truck or boat.



How TachMatch Works...


Tach Input:

TachMatch accepts most standard tachometer inputs. If you have a standard coil and points ignition, connect TachMatch to your coil. If you are using an aftermarket system to control the coil, such as an MSD, TachMatch accepts its tachometer output signal. If you have a typical GM HEI ignition, the tachometer output signal drives TachMatch.




Cylinder Conversion:

If your tachometer is designed for a different number of cylinders than your engine, TachMatch can change the frequency appropriately to correctly drive your tachometer. Select from 1:1 (if your cylinder count does match), 8:6, 6:4, 6:8, 4:6, 4:8 or 8:4 ratios.



Tach Drive Output:

TachMatch sends the corrected signal to your tachometer. For most tachometers, the standard TachMatch is the solution. If you have a current-driven tach, choose the TachMatch I-Boost. If you have a vintage tach, such as an old SW or Sun tach, choose the Vintage TachMatch.



Standard TachMatch...

The TachMatch Model TM-02 is designed with computer-controlled internal circuitry housed in a plastic case. A 4-pin terminal strip is used for connection of the wiring (wires not included, but can be purchased below). To help solve any installation problems, it includes diagnostic tools, such as a LED that indicates power and if it is being triggered, and a special test output that can ensure that it is connected properly to your tachometer.

Here is more information about the TachMatch Model TM-02:

The standard TachMatch TM-02 drives most typical tachometers of today. If you are not in the United States, please see the bottom of the page for information about international shipping.

TachMatch Wiring Kit...

The TachMatch TM-02, TM-02-I-Boost and VT-01 are installed with four external wires connected to an internal terminal strip (see Instruction Manual links for details). Wire size can range from #14 to #22. If you don't have wiring supplies readily available, the model WK-01 wiring kit consists of four 36"-long wires, one each of red, black, orange and white. Also included are four butt-connectors and two ring terminals.

Wire is high-quality, made in USA, 18-AWG stranded. Terminal style may vary from that shown in picture. This kit is only available with purchase of a TachMatch or MeterMatch, and does not add any shipping charges.

TachMatch for Current-Driven Tachs...

Some earlier vehicles (such as the early 70's Datsuns and Smiths/Jaeger tachs labeled as RVI on the face) use a current-driven tachometer instead of a voltage-driven tachometer. These types of tachometers can usually be identified by some loops of wire around the connections at the back of the tachometer. It takes more current to drive these tachometers than can be provided by the TachMatch TM-02. The TachMatch model TM-02-I-Drive, is designed to work with this type of tachometer.

This unit functions the same as the standard TachMatch TM-02, with the exception that it includes an external power resistor and internal changes to provide the current necessary for current-driven tachs.

See the instruction manual below for details of installation.

TachMatch for Vintage Tachometers...

The Model VT-01 Vintage TachMatch is for driving early tachometers that used a separate control box, such as the Sun EB/BW sender. This unit can drive most early tachometers, including Sun, Stewart-Warner (SW) and Radatron units that have simple + and - terminals on the back.

The Vintage Tach Adapter accepts most common tachometer input signals (same as TachMatch TM-02). For adjustment purposes, it has a "calibrate" signal that provides a known RPM output. When this signal is enabled, you adjust the TachMatch output, via course and fine adjustments, until your tachometer reads the correct RPM.

Details of it's connection and calibration can be found in the instruction manual below.
