Warning

•Do not connect or disconnect the Lambda Sensor

while powered, only do so when unpowered.

•The Lambda Sensor gets very hot during normal

operation, be careful when handling it.

•It takes roughly 30 seconds to 2 minutes to warm up

the sensor. Once the sensor is warmed up an engine

start could create condensation in the sensor, this

may cause thermal shock and damage the sensor. It

is best to power off a power source that is “live”

when the engine starts.

Sensor Exhaust Installation

•The Lambda Sensor should be installed between the 0

o’clock and the 2 o’clock position, less than 60 degrees

from vertical, this will allow gravity to remove water

condensation from the sensor.

•For all Oxygen sensor installations the sensor must be

installed before the catalytic converter.

•Avoid running the sensor to hot!

•Never leave an un-powered sensor in the exhaust system

Double check VCC&GND pins on aftermarket OLED-screens! Low budget/quality

screens can cause freeze and hang up of Tiny Wideband Controller!

Initial stand-by screen will show:

•Icon Sensor connection

•Icon GP2 ground status (GP2 not grounded= NO START)

•Icon Battery voltage

After succesfull start, the screen will show:

•Temperature value

•Lambda value

Starting and operating

Linear output settings:

0V = Lambda 10.20 = AFR 22.35

5V = Lambda 0.650 = AFR 9.50

Starting of the controller can be done by grounding “GP2” (solder

bridge on PCB) or external start grounding on molex connector,

with customer requirements setting.

Ie:start lambda controller only after engine starts. (programmable

output function within stand-alone ECU)

Not grounding of pin “GP2” will result in a standby lambda

controller! Blinking LED.

PC Layout

For easy integration we'll share the layout so the controllers can be

integrated in to own projects.
