I'd also be curious to know what's different in the RSX vs. I'm building a full race motor and will only have a primary oxygen sensor and will probably run leaded fuel which kills my O2 sensors about every 4 months.

I ran this with the Innovative LC-1 controller. Maybe you could use a controller along with a less expensive O2 sensor? But the controller and sensor is less than the price of just the RSX O2 sensor. Just a thought while I think outside the box. They don't require any power to produce an output, and the ECU can just read the voltage from the narrow band sensor.

Wideband o2 sensors add an oxygen pump cell and reference cell with heater to the Nernst cell. A controller regulates the current through the oxygen pump cell and also the heater current. The ECU cannot read a wideband sensor and there must use a wideband controller to run the o2 sensor. The wideband o2 sensor does not produce a voltage, but rather the amount of current through the oxygen cell tells us the AF ratio.

The difficulty is that the wideband controller must be matched to the o2 sensor. The reason is that the amount of cell current and heater current is critical for the life of the o2 sensor. Cold start current regulation is very important and it actually is possible to destroy an o2 sensor in a single cold start. This is why we do not recommend that people wire in anything at all to the o2 sensor wiring.

An external AF meter will not read the wideband o2 correctly, and more than likely will consume enough current to throw off the reading drastically. Swapping o2 sensors is equally as hazardous. To replace the RSX o2 you will need to find an exact equivalent o2 sensor, as the wideband controller electronics is integral with the ECU and cannot be replaced nor altered. The other options would be to run a cheap narrowband o2 sensor, and use the secondary o2 sensor input for closed loop which you will be able to do for the next KManager releaseor to use an external wideband controller which uses a cheaper wideband sensor and feed the analog output from it into the secondary o2 sensor input as above.

With each new model year, manufacturers are adding more oxygen sensors to better manage engine operation. Some high performance engines have an oxygen sensor for each cylinder as well as one for the rear of each catalytic convertor.

The sensors are located either underneath the hood or underneath the car. The oxygen sensors are connected screwed to the exhaust pipe, either in front or back of the catalytic converter. The front upstream sensors measure the amount of oxygen in the exhaust system. The purpose of the front oxygen sensor s is to measure how rich or lean the gases are as the gases exit the combustion chamber. Depending upon whether the exhaust gas is lean high in oxygen content or rich low in oxygen contentthe amount of fuel entering the engine is adjusted by the engine management computer to try and maintain an ideal mixture that produces the lowest emissions output from the catalytic convertor.

Rear downstream sensors are located behind the catalytic converter. The purpose of the rear oxygen sensor s is to monitor the oxygen content of the exhaust gases leaving the catalytic convertor. If one or more of the oxygen sensors are faulty, your car may not pass the emissions test. If you drive your car with a faulty oxygen sensor, you may get poor gas mileage and it can damage the catalytic converter. Keep up with the tune-ups.

If check engine light is on, don't drive the car too long without getting it inspected. If check engine light is flashing, pull over and get the car towed to avoid costly repairs. Ask the mechanic to inspect the vacuum hoses and leaks in the exhaust system. If the vacuum hose or exhaust system is leaking, it will display an oxygen sensor fault code.

Replacing an oxygen sensor may not fix the problem.Hondata makes hardware modifications to the ECU enable it to work with the different sensors and actuators found on the ECU.

How to Replace an Oxygen Sensor in Your Car (Air Fuel Ratio Sensor)

Hondata only sells adapter harness with the modified ECU. Within USA this product is legal only for racing vehicles which may never be used upon a highway. To verify if you have a genuine adapter harness, contact Hondata with the serial number of your K-Pro. In the example below the 05 RSX was equipped with a cold air intake. This engine responds better to tuning than the K20A2, probably due to the better cams and the fact that the stock ECU runs so rich at the top end.

A race header, with tuning will provide a significant increase in the mid range and top end torque. The Japanese part numbers for the ITR intake cams are:. This is because there have been three revisions of the engine.

I tried putting bolt ons, making it look pretty, a turbo kit and nothing seemed to helped it The car feels and pulls sooooo strong its unbelievable.

I raced my friend with a turbo prelude, port and polish, higher boost etc, and i can literally say that I left him like he was standing still! Before Hondata we were pretty much dead even all the way to Yesterday, I gave him a 2 second lead and I railed him in soooo fast that I thought that he had either let off or slightly tapped the brake Hondata Traction Control works by monitoring the A.

Warning Within USA this product is legal only for racing vehicles which may never be used upon a highway. The RSX O2 sensor will not work. Some sensors must be disabled to eliminate errors generated by the ECU. Above MPH cruise control may not function smoothly and may cancel from time to time.
