--------------------------------------------------------------------------------

Yes I found this thread the other day while doing a search as despite what people have said, that all you need to do to reset the ECU is just a matter of taking the Negative off the Battery for 2 hours or overnight then re-connecting it and then thrash your ride for the next 2 days. Nooo not at all! As their is a complete set of steps you have to do to after you have reconnected the battery which are as follows. Thanks to GTBob and Itchione for their input with these instructions from the EF & EL Workshop Manual:

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 1-2 minute in each of the following conditions.
NOTE- DO NOT TOUCH THE ACCELERATOR DURING ANY PERIOD OF THE 5 FOLLOWING ADAPTIVE PROCESSES.

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.

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 Drive, 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.

*As a clarifying note, I guess that for steps 3, 4 & 5 you can place the car in D with the handbrake firmly applied.

I recently followed these steps and I must say my Falcon has a lot more smoother and responsive acceleration now

Is the reboot process much the same in earlier EB EEV4's??

I'm currently using a NC2 Tickford sportsman (green top) ECU.

How do you know it runs rich on the passenger side?

If that is the case, then most likely its a dud oxygen sensor for that bank of cylinders.
