8) The purple wire
Be careful on how this wire is to be used, most applications will not
benefit from it being connected. The following illustrates its operation.
When the purple wire sees a ground signal, it will not allow the MAP sensor
signal within the controller to increase. The purpose is to limit injection in the
process of spooling up a larger turbo with a less than adequate torque converter.
In other words, grounded purple wire=no injection system. Simple test is to use
a pushbutton switch temporarily mounted. One leg to ground, and the other the
purple wire.
Another tip that can be done is to use it to control how fast the alcohol ramps up
by placing a capacitor from it to ground. When the ground is released, the time it
takes the capacitor to charge varies the time for the system to resume normal
tracking. The larger the value, the longer it takes. Typical values to experiment
with are 220, 330, 470, 1000 UF at 16volt electrolytic. I would leave this type of
experimenting to be done when the system is up and fully functional. Most
vehicles will never see benefit from using this procedure, it was added to
increase the flexibility of the controller. Again, may not see a benefit from its
use, and can cause more harm than good. Use accordingly with caution.
9) Final
At this point you’ve concluded the installation, first thing to do is before putting
alcohol into the tank, is turn the ignition on the vehicle “ON” and set the blue
gain knob to the middle position. Next depress the black test button and observe
the “turn-on” LED illuminates RED. At this point also observe the low level LED
illuminates. If these checks are passed, next is put some liquid into the tank and
observe low level LED shuts off.
Start engine and assure everything checks ok. Idles fine, etc. Next is start
engine, place Gain knob in the “8” position.. and hold down the “Test” button
and watch the turn-on LED change from Red to Green. This will indicate pressure
has been developed. On the first time this is done, it may take a little longer
since air needs to be displaced. The motor will also bog down after a few
seconds. If the pressure setting on the switch is set higher than the pressure
developed when the test button is depressed, due to voltage/settings on PAC,
etc.. The LED will NOT change color. And an adjustment to the pressure setting
on top of the pump may be required. It would be a good time now to recheck all
