To turn water-methanol system off,
select “OCTL” from main menu and then
select “OFF” from the “OCTL” menu.
Your injection system will now operate
with the default setpoint values. To tai-
lor the system’s activation points and
injection quantity to your specific engine,
please refer to the advanced tuning sec-
tion (below).
Advanced Tuning
The Banks Straight-Shot and Double-Shot
injection systems offer a wide working
injection flow range, as well as a wide
range of user-selectable setpoints to con-
trol injection by. The goal of these wide
flow- and adjustment ranges are to match
a progressively increasing amount of injec-
tion to your engine’s air-, load-, or EGT-
curve. To vary injection quantity across a
fixed size injection nozzle, supply pressure
to the nozzle must be varied (as opposed
to a typical automotive fuel injector, which
uses a fixed supply pressure, and varies
injection rate by switching the injector on
and off rapidly).
The Straight-Shot and Double-Shot sys-
tems vary supply pressure by increasing
the duty cycle supplied to the injection
pump. A low duty cycle supplies mini-
mal power to the pump, and creates a
low output pressure. Increasing the duty
cycle increases the power supplied to the
pump, generating an increased output
pressure (and increased flow across the
injection nozzle). Flow across the nozzle
does not increase linearly with pressure,
however - the injection controller and
the injection pump compensate for this
to a degree. To learn more, and view full
nozzle flow and pump capacity curves,

Set the first reference value (B1 or T1)
to control when pump will turn on and first
duty cycle value (BDC1 or TDC1) to control
pump duty cycle at the first reference value.
For boosted vehicles, reference values are
boost pressure in PSI. For non-boosted
vehicles, reference values are percent open
throttle where 0 is closed throttle and 100 is
wide open throttle.
12a.
Scroll through main menu and select
“B1” or “T1”, depending on your application.
Scroll through the values and select the
reference value that you want the pump to
turn on. If configuring a StraightShot system
with only one injection stage, this setpoint
should be above your tyical light-load boost
/ throttle value. For DoubleShot systems
where a small injection quantity is desired
at light load, this should be set several PSI
(or %) below your typical light-load boost
/ throttle value. The default setting is 10
PSI, which should be changed to a much
higher setting (50% or more) if configuring a
throttle-based system.
12b.
Scroll through main menu and select
“BDC1” or “TDC1”, depending on your appli-
cation. Scroll through the values and select
the percentage of pump duty cycle at which
the pump will run once triggered by the first
reference value. The default setting is 30%
duty cycle - if this value is set too low, with
too large of a nozzle, it can cause a low ini-
tial pump output pressure which can result
in improper atomization at the nozzle. This
may also trigger a Pump Output Error code
if the 40 PSI pump output pressure switch
is not triggered. However, if this value is set
too high, the initial output pressure spike
and injection ‘hit’ can be too severe and
cause the engine to bog or misfire.

Repeat step 12 to set remaining refer-
ence values and accompanying duty cycle
percentage values.
: Straight-Shot systems
have two reference values with
accompanying duty cycle values.
Double-Shot systems have four ref-
erence values with accompanying
duty cycle values.
