I am having this same issue with my Microsquirt V3 setup. 4cylinder car with coil on plug ignition. rpm on tach is 1/2 that of true rpm (TS is correct rpm). When i change from normal setting to half setting in tach output, the rpms are 1/4 correct reading. WebStandards. To determine which standard a motherboard uses for the tach signal, check the voltage across the pins on the motherboard fan socket with an oscilloscope; there should be 0 V (ground - black), +12 V (power supply - red). For the tach signal, the wire is usually yellow or white, and an oscilloscope will show a +5 V square wave output.
