P3 Gauges Full Configuration Guide
P3 V3 General Setup
Only the OBD2 connection is required for gauge function, all other wires are
optional. We suggest connecting the gauge to your OBD2 port and starting your
engine to check functionality before installation.
P3 V3 Operation Details
Available Readouts
*all readouts are not available on all models - see product page for your vehicle to verify
available readouts*
boost: Boost/Vacuum. Can be read from MAP sensor through the OBD2 port or by add-on
analog boost sensor. Can also be read by wire tapping T-MAP sensor on some BMWs. Boost is
shown in PSI and vacuum is shown in inHg. Can also be configured to read boost/vacuum in
BAR.
Coolant: Coolant temp. Unlike the needle on your dash, this will show you your exact coolant
temp. Can be read in either Celsius or Fahrenheit.
AFr: Air/Fuel Ratio. Shows you how rich or lean your engine is running. Measured in XX.XX parts
air to 1 part fuel.
IAT: Intake air temperature. This is the reading of the temperature of the air entering the
engine. Can be read in either Celsius or Fahrenheit.
IAT2: Post-cooler / heat exchanger. This is the reading of the temperature of the air entering
the engine. Can be read in either Celsius or Fahrenheit.
OIL: Engine oil temperature. This is the temperature of the oil in your engine. Can be read in
either Celsius or Fahrenheit.
CAC-AIr: Charge air cooler temperature. This is the temperature of the air in your charge air
cooler. Can be read in either Celsius or Fahrenheit.
Igntn: Ignition timing. This shows the time at which the spark plug is fired in relation to the
position of the piston. Measured in degrees before or after TDC (Top Dead Center)
tRAnS: Transmission fluid temperature. This is the temperature of the fluid in your automatic
transmission. Can be read in either Celsius or Fahrenheit.
OIL-PRES: Engine oil pressure. This is the pressure of the oil in your engine. Measured in PSI.
Egt: Exhaust Gas Temperature. This is the temperature of the exhaust gas as it exits your
engine. Can be read in either Celsius or Fahrenheit.
throttle: Throttle position. This is the measurement of how far the throttle plate is opened. Can
be measured in either percentage or degrees open depending on your vehicle.
rp-Shift: Engine speed/RPM. Also has a programmable shift light that can be set in the
configuration menu. Measured in rotations per minute.
Speed: Unadjusted vehicle speed taken from ECU. This reading is not adjusted like your
speedometer is. A small percentage is added to the speed shown on the cluster (in addition to
the unadjusted speed) by the manufacturer for legal reasons. May vary from speed shown on
cluster. Can be measured in either MPH or Km/h.
batt: Battery Voltage. This can be used to monitor battery and alternator performance.
Measured in volts.
0-60: 0-60 acceleration timer. Starts automatically as soon as vehicle speed leaves 0.0 MPH and
stops automatically as soon as vehicle speed reaches 60 MPH. Time will display until vehicle
comes to a stop. Measured in seconds. (Reads 0-100 when configured to Km/H)
0-100: 0-100 acceleration timer. Starts automatically as soon as vehicle leaves 0.0 MPH and
stops automatically as soon as the vehicle reaches 100 MPH. Time will display until vehicle
comes to a stop. Measured in seconds. (Reads 0-160 when configured to Km/H)
60-130: 60-130 acceleration timer. Starts automatically as soon as vehicle speed goes above
60.0 MPH and stops automatically as soon as the vehicle speed reaches 130 MPH. Time will
display until vehicle comes to a stop. Measured in seconds. (Reads 100-210 when configured to
Km/H)
60-0: 60-0 braking timer. Starts automatically as soon as vehicle speed drops below 60.0 MPH
and stops automatically as soon as the vehicle speed reaches 0 MPH. Time will display until
vehicle begins moving again. Measured in seconds. (Reads 100-0 when gauge is configured to
Km/H)
100-0: 100-0 braking timer. Starts automatically as soon as vehicle speed drops below 100.0
MPH and stops automatically as soon as the vehicle speed reaches 0 MPH. Time will display
until vehicle begins moving again. Measured in seconds. (Reads 160-0 when configured to
Km/H)
How To Remove a Readout
TO REMOVE AN UNWANTED READOUT
1- While gauge is running in gauge mode, TAP the right button to cycle to the readout you
would like to remove.
2- HOLD the left button until you see "- - - -" (while holding the left button you will see the bar
graph scroll back and forth across the screen)
The reading is now removed until you restore it. (see instructions below)
How To Restore Removed Readouts
TO RESTORE A REMOVED SETTING
1- HOLD both buttons until "ConF" appears and then release.
2- TAP the right button until you see "cc.x" ("x" being a placeholder for several different
options) You can find the correct cc setting for your car in the configuration chart above.
3- TAP the left button to cycle through the cc options and stop once you get to the correct
setting for your vehicle. (perform this step even if the cc setting is already correctly set for your
vehicle)
4- Once you are back to your correct cc setting HOLD the right button until the screen turns off.
(this saves/exits the menu)
5- Start your engine (if not already running) and the gauge will turn on. (It will take a little
longer than usual on the first startup after completing these steps)
This process forces the gauge to "re-scan" the ECU and pull all the readings that it can. All your
readings should be restored at this point.
PEAK RECALL:
The gauge offers peak recall of the PEAK VALUE on the selected mode, since the last recall, or
since the vehicle was started. In addition to this, for 2008+ model year cars the gauge also
stores peaks for EgT, Air, Coolant in the background, so that you can switch to that mode later,
after a lap for example, and recall your peak temperatures. A quick tap of the left button will
show your peak value.
Code Reading / Code Clearing
CODE READING: Code reading is performed automatically on startup. You can also read codes
on the fly by following the steps below -
1- HOLD both buttons until "ConF" appears and then release. (screen will then change to
"d.t.c.")
2- TAP the left button (code(s) will then be displayed one at a time)
CODE CLEARING: To clear codes you will need to follow the steps listed below -
1- Make sure your vehicle is KOEO (key on, engine off)
2- HOLD both buttons until you see "ConF" appear (display will then automatically switch to
"d.t.c.")
3- HOLD the left button until "CLrd" is displayed. (display will show "HoLd" while holding the
button and then switch to "CLrd" once clearing is completed)
(In some situations a code clear may be completed while the engine is running but KOEO is
recommended)
