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.
• PlugthesensorintotheRPMportintheSR3300T
receiver.
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.

head temperature. This is useful in tuning engines and in
preventing damaging over-lean runs.
