Correct Boost Sensor Installation
•
Because of the nature of the sensor reading absolute atmospheric pressure your gauge out of the box might read a positive or
negative value number when the engine isn’t running. (This is quite normal). Atmospheric pressure will read different values
between sea level and your location.
For an accurate boost reading its important to calibrate the pressure offset on your gauge. Note: there are two units of
measurement that can be used for boost sensor calibration: BAR and PSI. (Offset calibration will have to be adjusted depending
on the gauge mode chosen in the initial setup). The goal here is to get the boost gauge to display 0.0BAR or 0.0PSI when the
engine isn’t running. Follow the “BAR or PSI Offset Calibration” procedure in the detailed button operation on page 5.
Handy tip:
Buy JRP weld in bung and take
to a professional exhaust shop
for installation.

JRP boost pressure sensors read “absolute atmospheric pressure.” These are very high quality and rarely fail if installed cor
rectly.
The “barb” from the sensor should be installed in a way that it is self draining so that: oil, dirt and moisture don’t collec
t on the
internals. Ignoring this will lead to premature failure, and may not be covered by factory warranty.
Handy tip:
Self-draining installation should be
similar to exhaust probe installations
where the cable coming from the
back of the sensor should be
positioned between 10 - 2
(on a clock face). Not included
NOTE: (1/4NPT Thread adapters available at JRP)
(0.3 - 1A) Fuse
•
Disconnect the negative terminal
on the battery. Connect the power
wires as shown. Warning! Always install
a fuse where +12v is indicated.
•
Connect the EGT and Boost sensor
wires to their respective harnesses.
Follow procedure below for sensor specific installation.
•
(Optional) Install remote button wire and connect to the gauge.
•
Install 1x felt sticky strip (supplied) on inside edge of gauge pod.
•
Reconnect negative battery wire and start using the gauge
