Technical Specifications
- The Lambda Sensor Emulator simulates correct operation of the Lambda
Sensor when the car is running on GAS, avoiding the engine warning light coming
on and malfunctioning when running on petrol.
CARBURETTOR ADJUSTMENT BY MEANS OF THE LEDS
The 472 Emulator has 3 LEDS.
- GREEN LED = lean mixture
- YELLOW LED = right mixture
- RED LED
= rich mixture
- Start up the car and wait for approximately 5 minutes since the Lambda Sensor
needs to warm up to be able to operate correctly.
- Take engine speed up to approximately 3,000 / 3,500 r.p.m. and turn the rich
mixture adjustment screw so that the 3 LEDs come on alternately. At this stage run
the engine at idling speed and with the idle mixture adjustment screw adjust
carburation so that the 3 LEDs come on alternately.
Carburation is now complete.
We advise you to fix the Emulator in a vertical position, away from
possible water infiltrations and excessive heat sources (for example:
exhaust manifolds), so as to avoid to irreparably damage the Emulator.
To avoid bad workings of the Emulator we advise you to:
- pass the Emulator wires away from the high tension wire;
- make good connections. Please, pay attention that the best
connection you can do is a duly insulated welding.
Please advise the client that in event of a GAS electric system
breakdown, the Emulator automatically resets the original injectors
connection.
Do not absolutely open the Emulator box, especially when the engine is
running or the board panel is inserted. A.E.B. srl declines every
responsabilities for damages caused to things or person which
derive from the tampering of its own device provoked by
unauthorized persons.
