Configuration and Setup:
new P3cars Gauge is packed with many advanced features, but has been
designed to work for your car pretty much right out of the box. There are a few
settings that you may wish to change such as english or metric units, or
selecting the proper engine model for your car, or setting the trigger RPM of
the shiftlight. Below is a basic description of the gauges different features
connect ONLY the obd2 connector to check functionality before
GREEN=dimmer BROWN=Analog1 BLUE=Analog2 AUX PLUG=external boost sensor
Left Button TAP =
Peak recall (and start 15 second record)
15 sec playback
View Current Mode Name (If pressed again within 5 sec, change mode)
= Night / Day Dimmer toggled
(if auto-dimming is not enabled)
Boost: This mode will show vacuum and boost. Depending on settings in the
config menu this may be from VAG ecu data or an external analog sensor. Boost is
read in PSI by default and Vacuum is inHg. If you configure the gauge to metric
boost will be in BAR.
Coolant: This mode will show your current coolant temp. Unlike the needle on
your dash, this will show you exactly the temp that your engine is currently
running at, and is configurable between Celsius & Fahrenheit.
Air: Air intake temperature. This is the reading of the temperature of
the air entering the engine, and is configurable between Celsius &
Igntn: Actual ignition timing. This mode will show you the ignition timing
of your engine in real-time.
Egt: Exhaust Gas Temperature. This is the temp of the exhaust gas as
calculated by your ECU.
Throttle: Actual throttle plate position. Use this mode to see how your car
changes the actual drive by wire throttle blade in relation to what your foot
tells it to do.
rp-Shift: RPM readout. It can be handy to use this mode to see an exact RPM or
to record/playback and see your shifts.
Speed: Actual roadspeed direct from VSS. This is the actual roadspeed value
of the car, uncorrected. This is the raw value, therefore it may not match your
cluster which tends to read high in many cars.
0-60: Zero to sixty Performance Timer. Come to a stop and this mode will
read “Rdy…” The gauge is ready for you to accelerate to 60. As you accelerate
the gauge will time you and automatically stop when you hit 60, leaving your
time on the screen. When you slow to zero again the gauge will change to
Voltage. This is the voltage of your cars power system, anything between 13-14.5
volts while running is normal.

For gauges with "CAR" config options:
Car.0 FSI Golf R, Mk5 2.0t Cars (GTI,
Jetta) K-Line Golf/Jetta Mk4/TT USE bSt.d SETTING, bSt.F for APR Flash, bSt.A
for analog sensor
Car.1 TSI TSI/TFSI 2009+ mk6 2.0t cars
with TFSI motor USE bSt.d SETTING, , bSt.A for analog sensor
Car.2 FUTURE USE
Car.3 3.0t motor (S4, S5 with 3.0) K-Line
Audi ALT and diesel VW USE bSt.d SETTING or bSt.C with diesel, , bSt.A for
ANLG Analog sensors only, silent on
Car.4 K-Line Audi ALT and diesel VW, use
bSt.C with diesel
Car.5 Not Used
Car.6 Not Used
Car.7 Not Used
Car.8 Not Used
and Clearing Codes
For version 2.1 and higher there is a Clr.C option in the config
menu, use this to clear codes!
To read codes, simply start your car. If you have a code, the gauge
will read it back to you. If you have multiple codes the gauge will read off all
codes. For a definition of codes, please check
To clear codes on OLDER versions of the gauge, once again turn the
car completely OFF, while the gauge is off, HOLD BOTH BUTTONS, and then start
the car. The gauge will say “hold” to confirm that you want to clear you must
continue to hold for several seconds and then the gauge will read “CLRD” and the
codes will be cleared.
Setting up the Optional Analog
Your gauge has 3 linear analog inputs, 2 of which can be used as
universal displays for ANY 0-5v sensor. Do not hook up a device that sends more
than 5 volts or you WILL damage your gauge.
To enable an analog input, enter the config menu and set the A1
input to Y for yes. After doing this, 3 new options will
A1.DP, analog 1 decimal points. The
gauge will show 9999 on the screen, and tapping the first button will move the
A1.Lo, analog 1 Low volt, or Ov
reading, which the gauge will show when it sees ZERO volts on the input. -999
A1.Hi, analog 1 High volts,
or 5v reading, which the gauge will show when it sees FIVE volts on the input.
-999 through 9999
A1.bL and A1.bH, limits of the
bargraph for that input. L is the bargraph start, H is the bargraph
Simply set the values for the 0v and 5v readings of your attached
sensor, as well as the number of decimal points, and the gauge will interpolate
anything between 0 and 5v to the proper display.
According to the LC-1 wideband controller documentation, Analog
output 2 is the 0-5v output. By default it is 0V = 7.35 AFR and 5V = 22.39 AFR .
To configure our gauge to show this on the first analog input, we would use the
A1.DP, 2 decimal points, 99.99
After putting these settings onto the analog input, the gauge will
show proper AFR displayed in the Analog 1 gauge mode.
