	Many tachometers can accept the 12V signal emitted from the MJLJ module. however, some OEM tachs detect the RPM signal by sensing the high voltage flyback pulse from the ignition coil. In distributor based setups, there is only one ignition coil to detect this pulse from. With a wasted spark system like the Ford EDIS, you will have multiple coils providing this signal. Consequently you may need a way to detect this pulse across multiple coil-packs.
