BRP clains the ETec uses less fuel as other motors ... this is the case
at idle speed, where it hardly matters if a motor uses 20% more or less
fuel.

Above idle the ETec seems to use as much or 0-15% more fuel as other
motors. This is based on the performance data I have seen so far.

ETec pistons have a distinct shape with a dip in which a raised "nose"
sits. This helps at idle speeds but makes it less efficient at open
throttle.
