2.8 Tachometer
The tachometer output can directly drive any tachometer that is normally controlled by an ECU. If the
tachometer is from a vehicle where it was originally driven from the coil negative then you may need to
use a ‘tacho driver’ available from Omex to give a voltage spike to trigger the tacho. Some very old
tachos were ‘current’ driven and triggered from coil positive. Omex can supply a convertor box to allow
these to work.
