AXM-100 High Voltage Tach Adapter e34 Output energy: 103 mJMany classic tachometersespecially those from the 1970s and earlierwere designed to trigger off the negative terminal of the ignition coil, relying on a high voltage spike rather than a modern 012V square wave. If your vintage tachometer refuses to respond to an ECUs tach output (such as from MS3Pro, MicroSquirt, or MSPNP Gen 2), the AXM 100 is your solution. This adapter steps up low voltage square wave signals to mimic the original coil induced
