yeah thats it - unplug the ecu for a while then plug it back it.

The ecu forgets everything it has learnt about the engine and starts from scratch. It can help the ecu learn new mods quicker or forget bad habits, but generally it wont do anything that wont happen after a week of driving around anyway.

Any time the battery is disconnected, the transmission must re-learn the closed and wide-open throttle positions to enable the PCM to determine the proper gear to select for the appropriate throttle position. If the calibration is not performed following power source interruption, the transmission will shift hard and perform poorly from then on.

So to calibrate as follows:

First of all drive the car to normal engine temp and the thermostat has opened etc
Then to verify the correct idlespeed of the engine the following 4 steps should be taken with the vehicle being idled while stationary for approx 1 minute in each of the following conditions (total idling time approx 4 minutes)
NOTE- DO NOT TOUCH THE ACCELLERATOR DURING ANY PERIOD OF THE 5 following ADAPTIVE PROCESS.

1. Neutral with all electrical loads OFF.
2. Neutral with Air conditioning ON.
3. *Drive with all electrical loads off.
4. *Drive with Air conditioning ON.

*As a clarifying note, I guess that for steps 3. & 4., you can place the car in D with the handbrake firmly applied and DO NOT TOUCH the accelerator peddle.

After all this has been done then proceed to go on and to do these steps which actually set the TPS values;
5. To set the closed throttle referance position , place the transmission
in D, air con off, and let the engine idle for a minimum of 1 minute.
6. Next, set the wide-open throttle reference position by turning the
engine off- but leave the ignition switch to the "ON," position, ie;Idiot lights on etc, then press the accelerator
pedal to the floor and hold it their for 1 minute, minimum.
7. Then Place the gear selector to Park and switch off the ignition.
8. Drive the vehicle and check for proper shifting patterns.
