If you want to reset the ECU without losing your seat and stereo settings, perform the following procedure:

1. Get in your car and insert key. (It doesn't matter if you close the door or not.)
2. Turn the key to the on (not start) position.
3. Press the gas pedal to the floor.
4. Hold the pedal to the floor for five seconds, then turn the key back to the "off" position (don't remove the key), then release the gas pedal.
5. Wait 2 minutes.
6. Remove key.
7. Done

Yes it works. Done it many times. Should work on all years.

That sequence may not work because I added the push to start and it doesn't physically require a key to be in the ignition. I have a key fob now

Now that is an interesting twist to the equation.

The other method is to disconnect the battery for a few moments. Unfortunately, that can also wipe out your radio, seat, mirror and steering wheel settings. You might think about how to simulate a key insertion. It may just involve having your fob close enough to be recognized. Do you no longer have a key slot?

I do but it's under the dash the key stays in the acc position at all times not the on position tho. I will still try it, now my question is how would you know if it did actually reset the ECU?

Sometimes you can hear it release an ac servo under the dash but usually not. I can usually tell just by how the car reacts to acceleration. It is no longer as sluggish as before (quicker reaction time to the pressing of the accelerator pedal).
