Available Readouts

Boost: Boost/Vacuum is read through the included P3 Analog Boost Sensor. Boost is shown in PSI and vacuum is shown in inHg. Can also be configured to read boost/vacuum in BAR.

Batt: Battery Voltage. This can be used to monitor battery and alternator performance. Measured in volts.

Peak Recall

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. A quick tap of the left button will show your peak value.

Boost Units Setting

b.PSI = Boost read in PSI

b.bAr = Boost read in BAR

Boost Pressure Resolution

Pr0.1 = Boost shown down to 1/10th units

Pr0.5 = Boost rounded down to nearest 1/2 unit

Pr  0 = Boost rounded down to nearest whole unit

Temperature Units Setting

dEg.F = Temperature shown in Fahrenheit

dEg.C = Temperature shown in Celsius

Display Dimmer Setting

d.  On = Default, display will be in “bright” mode each time vehicle is started

d.On.A = Auto-dim, if more than 5 volts is sensed on green dimmer wire the display will dim. If less than 5 volts is sensed on the green dimmer wire the display will be in “bright” mode.

d.On.P = Persistent, display will stay in “bright” mode until the user manually changes to “dim” mode and vice versa

Power Control Option

pCo.A = Automatic, the gauge will turn on and off with engine

pCo.b = Button, the gauge will not turn on after engine is started until the left button is pressed for 1 second (pressing right button for 1 second will show battery voltage)

pCo.S = Switched, the gauge will be on as long as it is connected to power

OBD2 / Analog Mode Setting

Obd2 = Analog gauge not compatible with OBD2 functionality

AnLg = The gauge will not communicate on the network and will only be able to read boost, battery voltage, and 2 analog inputs

Calibrate Analog Boost Sensor (engine must be turned off)

CAL.b = Tap left button and display will show “OpEn AIr SnSr” (to verify your engine is off) it will then show “tAP.1”. Tap the left button and then display will flash back and forth and then shut off. Your analog sensor is now zeroed out at atmospheric pressure

Factory Reset

F.SEt = Hold the left button until dots appear at the bottom of the screen to reset to factory default settings

Analog Inputs

3 Analog Inputs 

Yellow Purple Black  Dedicated port for P3 analog boost sensor

Brown – Analog input 1

Blue – Analog input 2

 

Setting Up an Analog Input using pre-configured scaling 

*directions shown for analog 1, directions are same for analog 2

1- Enter the configuration menu of your gauge by holding both buttons until you see “ConF”

2- Tap the right button until you see “A1.n” for Analog 1(brown wire)

3- Tap the left button to change it from “A1.n” to “A1.Y”

4- Tap the right button to select a pre-configured scaling setup (“EC”=ethanol content from ESVA / “Ft”=fuel temp from ESVA / “LC”=Air/Fuel ratio from LC-2 wideband kit)

5- Hold the right button until the screen turns off to save/exit the menu

 

Setting Up an Analog Input using manual sensor scaling

*directions shown for analog 1, directions are same for analog 2

1- Enter the configuration menu of your gauge by holding both buttons until you see “ConF”

2- Tap the right button until you see “A1.n” for Analog 1(brown wire)

3- Tap the left button to change it from “A1.n” to “A1.Y”

4- Tap the right button until you see “A1.dp” (this is the decimal point setting)

5- Wait for the screen to cycle to “9999” and then tap the left button to place the decimal point

6- Tap the right button to move on to “A1.Lo” (this is the maximum sensor value)

7- Tap/hold the left button to set your minimum sensor value 

9- Tap the right button to move on to “A1.HI” (this is the maximum sensor value)

10- Tap/hold the left button to set your maximum sensor value

11- Tap the right button to move on to “A1.bL” (this is the lowest value for bargraph illumination)

12- Tap/hold the left button to set your lowest bargraph value (no bars illuminated)

13- Tap the right button to move on to “A1.bH” (this is the highest value for bargraph illumination)

14- Tap/hold the left button to set your highest bargraph value (all bars illuminated)

15- Hold the right button until the screen turns off to save and exit the menu

 

5 Volt Power Source: If your sensor requires a 5v power source, you can use the purple wire on the gauge harness as your power source.

EXAMPLE CONFIGURATION – LC-1 / LC-2 AFR Controller:

According to the LC-1 wideband controller documentation, Analog output 2 is the 0-5v output.

LC-1 = BROWN WIRE. LC-2 = YELLOW WIRE.
LC-1/2 default output 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 following settings:
A1.DP, 2 decimal points, 99.99
A1.Lo, 7.35
A1.Hi, 22.39
A1.bL, 7.35
A1.bH, 22.39

After putting these settings onto the analog input, the gauge will show proper AFR displayed in the Analog 1 gauge mode which will appear in the running mode as AN 1.

Troubleshooting Checklist

1 – Start your engine

  • Your gauge is designed to turn on and off with your engine automatically. Start your engine, your gauge should power up within a few seconds of startup.

2 – Check your connections

  • 1- Disconnect power harness from main harness
  • 2- On the power harness connector, check for 12 volts on the pin for the red wire
  • 3- On the power harness connector, check for ground on  the pin for the black wire
  • 4- Main harness to analog control box connection
  • 5- Control box to display connection
  • (If you are connecting to the OBD2 port for power and do not have 12 volts at pin 16, check your OBD2 fuse (reference your vehicle’s owners manual for fuse identification)

 3 – Check your configuration settings

  • 1-  HOLD both buttons until you see “ConF” then release (the gauge will then switch to the “bSt.A” setting)
  • 2- TAP the RIGHT button 7 times and verify your power control setting is correct for your application
  • (PCo.A- Automatic ON/OFF  |  PCo.b- Button press required to turn on gauge each start up  |  PCo.S- Switched power source, gauge always on when power applied)
  • 3- If your gauge still does not function properly, include the complete list of configuration menu settings in your support request – we will need this list in order to assist you
