Initial Gains in Fuel Economy-

[timetowinarace]

1. Has anyone installed a hho unit with no other modifications and seen initial gains in fuel economy BEFORE the ecu made compensations.

2. Is anyone still getting better economy and haven't made any other modifications other than the addition of the hho unit.

3. Has anyone installed a hho unit on an older non computerized vehicle without making any modifacations to a/f mixture or timing and seen fuel economy gains.
