Yes and No

No answer: you can not get an performance upgrades by changing your OBD-II sensor. in fact, if you alter that your check engine light will come on and you wont pass any smog checks.

Yes answer: there are many companies out there that will reprogram your cars computer for you. Hondata is one of the companies that is very good at doing this.

Now if your car is stock there is no real benefit to doing this because your cars computer is optimally programmed from the factory. If you add an after-market air intake and exhaust then that will increase your performance a few horse power but still isn't worth a computer being reprogrammed. in that case you would just look for a air/fuel ratio meter that can allow you to adjust to make it more optimal for your new intake/exhaust or header. HKSusa.com makes a nice air/fuel ratio meter.

Only time you really will get any solid benefits from re-programming your cars computer (also known as flashing your ECU or computer) is after you have installed aftermarket intakes, head, exhaust, new cams, or pulleys, internals or turbocharged or supercharged your car. After everything performance wise is done, then you can reprogram your computer to take all the new factors in and adjust and optimize to the best performance.
