Right Button HOLD = EXIT config menu and SAVE settings.
|D.On||On or Off or On.A or On.P||Turn the gauge display ON or OFF or ON-Auto-Dimming(if you have attached the green wire to your dimmer line) or ON-Persistant-Dimmer(for dimmer setting not resetting on restarts.)|
|En.Y||Y or N or b||English units? No = Metric, Y = English, b = Boost only (boost in PSI, rest in metric)|
|Pr0.1||0.1 or 0.5 or 1.0||Pressure resolution/decimal point. 0.1 = tenths, 0.5 is rounded to 5 tenths, 1.0 = whole numbers only|
|U.bg.Y||Y or N||Vacuum bargraph in boost mode – set to N for no bargraph while in vacuum|
|SL.57||30 – 80||Shiftlight activation RPM x 100, default is 5700|
|Bst.d||d or A or n
||Boost reading – digital or analog or none. (analog is for gauges with boost sender and tubing to manifold) Digital is used for n55 only.|
|A1.N||Y or N||Enable or disable the first analog input (brown wire)|
|A2.N||Y or N||Enable or disable the second analog input (blue wire)|
|Clr.C||None||Hold the first button to clear codes.|
|Cal.b||None||Calibrate the analog boost sensor to your ambient conditions. — tap left button after confirming engine is off|
|n54||n54, n55, A.n55, F30, n63, AnLg||Select engine type – this will enhance the accuracy of the gauge. A.n55 is for n55 with voltage tap on the OEM sensor connected to analog 2. AnLg mode forces the gauge to use analog only, no canbus. NOTE: for A.n55 and F30 modes, the 2nd analog input (BLUE WIRE) is configured to allow you to attach this wire to the 0-5v output of the manifold pressure sensor on the engine and use analog boost (bSt.A) which will then use this connection for boost readings.|
|Flo.N||Y or N||Enable or disable the first analog input (brown wire) to be meth flow — will add “Flo” and “Bst-Flo” gauge modes.|
For gauges with "CAR" config options:

ANLG Analog sensors only, silent on canbus
Car.4 N54 BMW's with N54 engine USE bSt.A SETTING
Car.5 N55 E8X, E9X BMW's with N55 engine USE bSt.d SETTING
Car.6 N55 with analog tap on AN2(blue wire) BMW's with N55 engine and a t-map tap USE bSt.A SETTING
Car.7 F30 and F20 and F10 Cars N20 and N55 engine USE bSt.d SETTING
Car.8 F10 Cars n63 and s63 engine USE bSt.d SETTING
Reading 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 search your 4 digit code on the forums.
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 Inputs
Your gauge has 3 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 appear.
A1.DP, analog 1 decimal points. The gauge will show 9999 on the screen, and tapping the first button will move the decimal point. A1.Lo, analog 1 Low volt, or Ov reading, which the gauge will show when it sees ZERO volts on the input. -999 through 9999 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 end.
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 following settings:
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.
