FACTORY TACHOMETER Setup
Normally the distributor provides the input signal for the tachometer, but with the Honda
COP kit installed your car will no longer be using a distributor. The tachometers signal
wire is now left connected to nothing. There is however a simple fix for this provided by
the Series 2 EMS. The Series 2 EMS provides a signal output for the tachometer.
Connect the signal input from your tachometer to the appropriate pin for the EMS you
are using. Pin locations for the 30-6040, 30-6050, and 30-6060 Series 2 EMS units are
shown below in Table 6. The ground and power wires of your tachometer will still
remain connected as they were before.

Ensure that the tacho signal that will be generated by your EMS is set up correctly.
Open the calibration you are using in AEMTuner and view the “Tacho-Speedo” tab.
Make sure the “Tacho Options” table matches the settings shown below in Table 7 and
that the Tacho table looks like Figure 30 below.
