DME / ECU flash - engine sound change
 
Out of interested: I just flashed my ECU with the stock for tune in years. I immediately noticed an engine note change at idle. It change to a more deeper smoother baritone sound rather than the usual rasp...I wonder if the fuel delivery is different enough at low rpms such the sound is altered.

Engine note changes are easily heard (in a garage) with my bypass exhaust
