6.2 MPG Calibration

This mode allows you to calibrate the fuel efficiency reading. It
is recommended that you leave this at the default value of

1.00. However, if you’re MPG readings are inaccurate due to
the type of vehicle you have, you can manually correct for this
by adjusting the MPG Cal. Press the set button to enter you
into the set mode. When you’re in this mode, press the mode
button to change the digit position. Press the set button to
increment the number. To exit, press the mode button until
none of the digits are blinking.

Special Considerations and Background Information:

Kiwi MPG derives its fuel efficiency from your vehicle’s factory
sensors. There are two types of sensor that can be equipped in
your vehicle. A manifold absolute pressure sensor (MAP),
and/or a mass air flow sensor (MAF). If your vehicle is
equipped with a Mass Air Flow sensor, your unit will display
“CALF” when entering into this mode. If your vehicle is
equipped with a manifold absolute pressure sensor (MAP),
your unit will display “CALP” when entering into this mode. In
most vehicles equipped with a MAF sensor, calibration is often
not necessary and it is recommended that you leave this
setting default at 1.00. For vehicles equipped with a MAP
sensor, calibration is often necessary to you to achieve the
best accuracy.

Calibration Techniques:

Look up your vehicle’s EPA’s HWY fuel efficiency rating. If you
can’t find your original paperwork that came with your vehicle,
you can also browse through the government database at

www.fueleconomy.gov. Once you’ve determined your HWY

reading. Find a level paved road and drive 50MPH. Keep a
steady speed and have a passenger adjust your MPG’s
instantaneous reading to match your EPA reading by adjusting
the MPG Cal parameter. Be sure to drive both direction on the
road to counterbalance the slope of the road and any wind
conditions to achieve the most accurate results. Keep your foot
on the gas as steady as possible to avoid any jerks and pulses
to achieve the most accurate reading.

6.3 Tank Size

This mode allows you to set the gallon size (or liter size). Press
the set button to enter you into the set mode. When you’re in
this mode, press the mode button to change the digit position.
Press the set button to increment the number. To exit, press
the mode button until none of the digits are blinking. If your
units (see section 6.4) is set to 0, the reading reflects gallons.
If your units (see section 6.4) is set to 1 or 2, the reading
reflects liters.
