East Coast Supercharging ECS Alky C5 - Manual (Page 10)

8) Final
At this point you’ve concluded the installation, first thing to do is before putting
alcohol/water into the tank, is turn the ignition “on” and set the blue gain knob to the
middle position. Next depress the black test button and observe the turn-on LED next to
the boost gauge light up. At this point observe the low washer fluid lamp, which should
also be lit since the tank is empty. If everything checks ok, fill the tank with
alcohol/water, and check for leaks coming from fittings that may have not been
tightened. Start the vehicle and hit the test button, observe the turn-on LED illuminates.
If these tests are passed, then you’re ready for a road check. And on your maiden
voyage bring the boost up slowly and as the gauge goes past 4 PSI boost, the turn-on
LED will illuminate. If it doesn’t, do not continue the test and see why the MAP sensor
isn’t working. This is very important.
If it does work correctly, then proceed to increase the boost level observing how the
engine feels and assure there is no surging when the system is spraying. If this part is
passed, watch your knock readings, and roll into the throttle to your desired boost level.
Stabbing the throttle on some cars can induce false knock. Just trying to make sure
what you see is real or false. Also observe the turn-on LED and it will change color from
red to green when initial pressure is developed. This can be changed via the adjusting
screw on top of the pump. Outward decreases activation pressure, inward.. increases it.
Typically I will set so it comes on early on. You may find our setting to be acceptable.
Adjusting this screw has no effect on the system or its delivery. Its for changing when
the LED indicator flips color.
From this point fine tuning of the system can be performed.
9) Fine tuning
Although most cars will work with the system setup as is from factory default settings,
this is just a guideline. With the gain knob(blue) turned to minimum, you should see
some knock but not a whole lot. Typically less than 2 degrees at WOT. Increasing the
gain knob should make the motor go to zero knock. If your setting is at minimum and
you don’t see any knock, you may have too much alcohol being sprayed. The
adjustment that affects this is the knob inside the PAC controller labeled “INITIAL”.
Turning this screw counterclockwise reduces the ramp and puts less alcohol/water into
the motor. Small adjustments make big changes. Repeat the procedure until the motor
just has enough alcohol to curb the detonation, but not too much.
On certain applications, whereby chip/fueling is adjustable, it may be beneficial to
increase the initial and lower the fueling whereby upping the flow of alcohol through
the motor.
