Resetting Computer
I've seen posts where people talk about resetting the cars computer after a performance mod (example: exhaust system). Why is it necessary to reset the computer and how is it done? I recently installed a catback system. Never reset anything on previous cars, what am I missing? Thanks in advance for feedback.....

There are two reset procedures, one for the NVRAM and the other for the KAM. Neither will erase your radio presets and such like the method SpooledUp7 posted:
1) With the key in the off position, press and hold the odometer reset button and turn the key to on;
Continue to hold the odo button until the odometer reads "TEST" and then release.
2) Turn the key to off and repeat step one.
This will reset the entire PCM except the KAM which contains the sensor profiles amongst other things. You can reset it with the familiar procedure:
1) Turn the key to on
2) Depress the brake pedal rapidly 20 times in a row until the oil pressure gauge sweeps to halfway and back again.

the RX8 has an intelligent computer system where it identifies the driving style of the driver and adapts engine management sytem to accomidate the users applications. when you add a performance mod, the reason most people reset the computer is for the car to re-learn the performance of the car and how it responds to driving conditions, and the overall performance of the car
