the sensor so it is 1/8 inch from the flywheel.
Depending on your flywheel size, the sensor might
have to be mounted in different orientations.
• Iftheflywheelisreflective(baremetal),placeaflat
black decal on the flywheel so it passes between the
sensor and the flywheel when rotated. If the flywheel
is non-reflective, place a reflective decal on the
flywheel so that it passes between the sensor and the
flywheel when rotated.
Hint: We recommend applying a small
amountofCAgluearoundtheedgesofthe
decal to ensure strong adhesion. Be sure to
only glue the edges and do not cover the top
of the decal.

RPM/SPEED SENSOR (ELECTRIC)
In electric cars and trucks, the rpm sensor is mounted
near the spur gear and gets rpm readings directly
fromthatgear.Aconversioninthetransmittercanbe
programmed to give speed in mph or rpm. See the
Telemetry Speed Unit section on rpm and speed for
moredetails.Amountisprovidedthatallowstherpm
sensor to be conveniently mounted in many applications.
Because of the diverse types of electric vehicles, it may
be necessary to fabricate a mount from Lexan for some
types of vehicles.

that wraps around the head of the engine to monitor
head temperature. This is useful in tuning engines and in
preventing damaging over-lean runs.
