today we're going to demonstrate self-tuning fuel capabilities of the new
Holley
Avenger HP and dominator EFI system
we're gonna demonstrate the amazing capabilities the self-tuning feature
offers
on our DPS engine dyno here at Holley
for this demonstration we're going to remove 50 percent of the fuel from the
base fuel table from this engine
after that we'll enable the self-tuning and will demonstrate
how quickly self-tuning relearns fuel necessary for this engine
the first thing you do is allow the engine to idle
let the engine idle for few seconds and you can watch the screen
as the self-tuning is performed you could see
on what's called the learn table that it's adding fuel back in necessary for
the engine to run properly
after the idle learning is completed
we're going to go and do a wide-open throttle pull
to demonstrate how quickly the system can learn realize that this engine has
has had fifty percent of the fuel removed from what it needs
will start the dyno pull we can watch the self-tuning screen
and watchin as it adds fuel during the pull
since such an extreme amount of fuel was taken out
we cant do a full learn on the first
dyno pull so we'll do one more pull
we'll now make another dyno pull so that the system can do all learning it needs
after the second dyno pull
all the learning that was necessary has been performed
with the learning complete at idle and at wide open throttle
we'll now allow the engine to learn at part throttle on higher rpms
this would be simulating driving a vehicle around on the road we could just
increase the throttle
allow the engine to learn at different speeds and loads this demonstration on the
engine dyno
duplicates exactly will happen as you drive your vehicle around
with your Holley Avenger HP or Dominator system
the self-learning fuel strategy eliminates one of the most difficult
time-consuming areas of EFI tuning
and that is tuning the base fuel table
all the advanced new features in the new Holley Avenger
HP and Dominator EFI system will now turn the
fuel injection tuning process into an enjoyable and fun experience
rather than the more difficult and complicated process that it typically used to be
we hope you enjoyed this demonstration of Holley's advanced self tuning
fuel strategy and hope you see how it will benefit you
in your quest for EFI tuning perfection
