O2 Performance Chip

This unique override results dramatic changes in horsepower at the wheels. Whether you are looking for improved low end torque, crisp acceleration or you just want to blow everybody off the line, this unit will do its job. Installation is easy, no special tools or skill required. You'll receive +10-30 additional HP, & extremely dynamic acceleration improved by up to 20 % depending on stock engine performance. You do not need to dismantle the ECU or solder its Eprom chip, since the signal of oxygen sensor performance chip fools the ECU resulting in higher horsepower, torque and acceleration as well. Enjoy a harsh engine, with outstanding acceleration without terrible flat pots. Detailed instructions, perfect fit. No check engine light illumination. FEATURES OF O2 / Oxygen Sensor Performance Chip: Improves engine performance by 10 %. Enhances Nm, throttle response, acceleration and low end torque. Preserves smog certification. Peps up acceleration by 15 %. Results higher top end speed if no factory speed governor exists. Easy universal 15-20 minutes installation. Chip cab be bypasses by a switch. Cures throttle flat spots.

WORKING THEORY

An automotive oxygen sensor, also known as an O2 sensor, lambda probe, lambda sensor, lambda sond or EGO (exhaust gas oxygen) sensor, is a small sensor inserted into the exhaust system of a petrol engine to measure the concentration of oxygen remaining in the exhaust gas to allow an electronic control unit (ECU) to control the efficiency of the combustion process in the engine. In most modern automobiles, these sensors are attached to the engine's exhaust manifold to determine whether the mixture of air and gasoline going into the engine is rich (too much fuel) or lean (too little fuel).
This information is sent to the engine management (ECU or ECM), which adjusts the mixture to give the engine the best possible fuel economy and lowest possible exhaust emissions.

If we alter the information delivered the ECU we may effectively affect engine horsepower.
This unit takes off the barriers applied by the ECU, it tricks O2 sensor signal, consequently delivers 10 % extra power plus noteworthy low end torque within the full RPM range without reduction of economy.

This device tricks pulse signal of oxygen sensor thus we can affect the air fuel ratio of the fuel mixture gaining more power, improving the efficiency of combustion and saving fuel. This add-on device delivers fuel-poor reading the ECU, besides a reading limit control is incorporated to avoid "signal out of range" error codes.

How can consumption be kept?

With  O2 / Oxygen Sensor Performance Chip,we arrange modified (lowered) air fuel ratio within the entire RPM range in order to attain more horsepower, better torque and improved economy. The throttle position will result more power. We tune up the engine slightly at the expense of emission has been overcontrolled nowadays by the manufacturers must comply with rigorous environmental protection regulations.

HOW IS SUCH A SPECTACULAR RESULT POSSIBLE?

The operation of injection system is significantly determined according to the voltage of oxygen sensor, therefore when we trick this signal we may control effectively the engine performance.O2 / Oxygen Sensor Performance Chip restores the original performance of the engine, is reduced by restrictions claimed by the regulations and laws of emission control.

INSTALLATION OF O2 / Oxygen Sensor Performance Chip:

Before installation please be sure that stock sensor is working correctly because result would be diminished if stock oxygen sensor did not emit proper signals: if your sensor were old or worn.
FACTORY RECOMMENDATION FOR MAINTENANCE OF O2 SENSOR(S)

1. SHOULD BE CHECKED AFTER EACH 20.000 MILES (32.000 km).
2. MUST BE REPLACED AFTER EACH 50.000 MILES (80.000 Km).

Easy steps

1. Cut the original harness between the factory plug and the oxygen sensor.
2. See colors & operations of each wire in car wiring diagram or search for your combination in charts below.
3. Connect the corresponding wires with terminals or solder them in place. (Hydrochloric acid recommended by soldering.)
4. Seal the contacts with the provided heat shrink tubing.
