Your engine
starts, idles, and
drives well. Enjoy
the Atomic EFI!
Do you have
drivability
issues?
If timing is off an engine
can struggle to idle
regardless of the fuel
system. Make sure the
distributor is in proper
alignment.
Has the Atomic
EFI had time to
learn all the parts
of your fuel maps?
Check to see that the fuel
system is maintaining
pressure. If the Atomic
looses fuel pressure for
any reason it will cause
the engine to run poorly.
Are you sure the
ignition timing and
rotor phasing are
correct?
Does the Atomic
EFI maintain
adequate fuel
pressure?
The Atomic is designed to
always hit the designated
Air Fuel Ratio Targets. If
these targets are much too
low or high for an engine it
will run poorly. Check to
ensure the targets make
sense for your engine.
Do the Air Fuel
Ratio Targets
make sense?
When there is an increase in
throttle position the engine can
require extra fuel that isn’t
accounted for in the regular fuel
maps. See page 12 to learn how
we solve this issue with the
“Pump Squirt” feature of the
Atomic.
Even a small exhaust leak can
alter the WBO2 readings. If this
happens it will have a dramatic
effect on the engine’s
performance. Always ensure
thre are NO leaks in the
exhaust?
Does the engine
struggle to keep
up during throttle
increases?
Are there any
exhaust leaks?
The engine is smooth
idling. Do you have any
drivability issues?
The Atomic needs run time in
each area of the fuel maps to
learn the best settings for
your engine. It could take up
to a week of normal daily
driving to adjust all the maps.
