I have twin Volvo D12-675 engines with EDC controls. Both engines idle at exactly 520 rpm. Is there a low/high idle function that can be set to bump the idle to up 650 or 700 rpm? I’m looking for a bit more power going in and out of gear during higher wind and fast tides without needing to use the throttles. There has to be a way to select or program this since everything is electronic, however have been searching for awhile and can’t seem to find the answer. Any help is much appreciated! Thanks!
