I wouldn't sweat it too much, unless your consumption is out of whack.

People have already pointed out the pros to it and the mods that can be done.

I don't know if it makes much difference, but it costs nothing to reset the ECU after changing plugs, rotor and dizzy cap (if cracked or scarred inside), fuel filter and air filter. Pull the fuse and leave it out for 10 minutes. Replace it. Let the car idle and then shut it down when warm. Restart and go for a calm drive using as much as the rev range as you can.

Like I said, chances are it will make no difference, but I find mine runs better after doing this after 20,000 kms.

That or it's just in my head
