TC UNIT O2
CONTROLLER
- LAMBDA
EMULATOR
We suggest to use the O2 controller
to further optimize both carburetion
and performances in transistors.
In latest generation motorcycles,
thanks to lambda sensor, the CDI
can rectify the fuel quantity to
be injected in order to reach a
constant carburetion even in Closed
Loop area.
The O2 controller permits to totally
control the carburetion as to obtain
the best air/fuel ratio.
Malossi Lambda emulator is a device
able to simulate signals from lambda
sensor which original CDI is expected
to receive. In this way, original
lambda sensor is used to obtain best
carburetion without the original CDI
noticing failures or mistakes.

Working
The O2 controller is equipped with
3 LEDs:
• the Power LED indicates correct
power supply;
• the remaining two LEDs show the
carburetion status.
After ignition of the vehicle, the
power and Rich (rich carburetion)
led lights up. After a period of sensor
warm up, if you are in the Lambda
closed loop control area, you will
see the two Rich and Lean LEDs light
up alternately. This type of action
highlights the correct functioning
of the device through continuous
calibration of the A/F title.

• Locate the Lambda sensor and
follow its cable until you reach
its connector.
• Disconnect the connector
insert, into the circuit, the O2
controller (Fig. 1).
Attention:
screw the ground ring

• Locate the lambda sensor
the vehicle head
• Follow the lambda cable until you
reach its connector
• Disconnect the connector and
insert, into the circuit, the O2
controller .
• Disconnect the injector connector
(5); insert, into the circuit, the O2
controller (Fig. 3).
Attention: please connect the eyelet
to the ground node located near the
