East Coast Supercharging ECS Alky C7 - Manual (Page 23)

Adding gain to the knob(clockwise) increases pump pressure output. If the knock is occurring
due to transitional, increasing initial pump speed or decreasing turn-on point will aid these
conditions. Again every vehicle is different, the initial and turn-on will more than likely never be
recalibrated once system is setup. They will not correct a tuning problem and/or engine fault.
Timing suggestions, Low timing and high boost. Setting up the fueling, timing, coupled with
the alcohol output requires time and patience. Do small steps at a time and enjoy the product and
its technology.
The pump features an allen screw to adjust pressure activation. Every vehicle is different, as will
be the setting of this screw. Suggestion is to have it sense pressure early on. If there ever is an
issue with the system(empty tank, tank leak, clogged feed line, etc) this will advise of a problem.
Although it can be set to activate under higher pressures. This is a personal preference. And the
brown wire can be used for triggering boost controllers as well. No pressure=no Hi Boost
TIPS
On applications like the Buick Grand National, I wire a 12 volt bulb across the pump output
terminals ( +, - ) . This allows me to see the bulb brightness increase as the boost level increases.
And light dimly when the initial pushbutton is depressed. Other options are the use of an electric
pressure gauge (optional) or mechanical pressure gauge (optional) to setup pressure. It is not
needed, but can be handy for initially setting up controls. Other options are the use of a
voltmeter across those terminals.
Most if not all street applications, once the knobs are set, they rarely get changed. Minor changes
to the gain knob is all that will usually be required. Keep an eye on the road at all times…and if
an unreasonable amount of knock is encountered, take your foot of the pedal and diagnose
problem.
