East Coast Supercharging ECS Alky 5th Gen - Manual (Page 16)

IMPORTANT NOTE: The “Black Pump Wire” on the main controller is not a ground.
Main controller wiring, green-violet-gray-orange-brown.
Green is connected to the MAP sensor signal wire. On in the case of Ford vehicles.. MAF
Gray is an auxillary output that will switch + voltage when system activates. Examples to
run a solenoid driver relay module, input to external boost controller, etc.. typically not
used
Orange/Brown twisted go to the Turn-on LED. These wires will flip polarity when
pressure is developed. Suggestion is to place turn-on LED near boost gauge to indicate
system has activated.
Violet wire is the negative trigger input terminal for pump speed
reduction. Grounding this wire reduces injection pump speed to initial pump pressure for
staging applications while drag racing. Intended application are E-brake switches.
The remote controller affords the user the flexibility of custom installing controls with
dash panels of vehicles or attaching control box as is. For custom installation, simply
remove screws from box and relocate controls and LED. A small jewelers screwdriver
will be required to remove knob assembly. Unibit drill bit makes graduated drilling holes
a snap.
Setup and Use
The remote controller features a knob that controls ON/OFF and GAIN. The LED next to
it indicates system is armed and the push button applies “initial” pump speed to the pump
for testing operation.
On the main controller is an access door. Opening the access door reveals two controls
internally labeled “TURN-ON” and “INITIAL”. The turn-on control allows the user to
set a turn-on voltage from 1.7volts to 5volts. Clockwise rotation increases the voltage
needed to trigger system. The “INITIAL” control determines how much voltage is sent to
the pump when the system is triggered. Typical settings are factory preset for 4 PSI turn-
on with a 2 volt output to the pump. These can be recalibrated by the user by simply
turning the controls clockwise to increase, counter clockwise to reduce. A LITTLE AT A
TIME. Use fingers or small flat screwdriver. An electronic voltmeter can be used for
initial pump setup as well. Procedure involves placing voltmeter across terminals on
power distribution block and pressing the push button on remote controller. Typical
setting is 1-3 volts. Next is the “Pump Gain Control” on the remote controller. This
control interacts with the initial pump speed control. Usual and typical settings place this
knob in the 12-2 o’clock position. It is used to ramp the voltage gain to the pump as the
signal from the MAP sensor increases. Turning this knob clockwise will increase output
voltage multiplication and slightly increase the initial pump speed. Only way to know
what is best suited for your particular application is trial and error.
