TechnoVersions V-Boost - Tach Adapter, Voltage Boost Module

Most tachometers can be driven with a 12v pulse signal, such as that provided by the standard TachMatch and the MSD-6 series. However, some tachometers need a stronger signal that more closely replicates the signal generated by the coil. The TachMatch V-Boost Module takes a lower level input signal, whether it be ECU output, MSD 6 tach output, or from a standard TachMatch TM-03, and generates a stronger signal to the tachometer, similar in function to the MSD 8920. Another application is when you are changing from a coil-style ignition to a system that uses an ECU. Often, ECU's, with a 5-volt signal, will not drive tachometers designed to use a 12-volt (or higher) level signal. This unit will convert from the digital-level signal to one which will drive your tachometer, similar to the Auto Meter 9117.
The TachMatch Voltage Boost Module does not do cylinder conversion. If you need that, it needs to be driven from a TachMatch TM-03.
