What I did to my mazda5 today:
I experimented with my MAZDA5's throttle by wire. googled
for 'throttle by wire calibration'.
I found this thread from a non-mazda forum:

1. First I followed exactly the procedure in the thread i.e. pedal
all the way to the floor.
-- Result: "Maybe the result is just in my imagination. But
There seems to be a 'change in feel'. Or 'the car
reacts to the gas pedal differently this time'.
2. Then I thought: "What If I press the gas pedal only halfway"?
-- Result: Definitely a 'new feel' is experienced.
I don't know what is the use for it though. But it does make the
mazda5 continously interesting.
