INPUT ACCESSORY GUIDE
Map - (Input 1 or 2) The PCV has the ability to hold
2 different base maps. You can switch on the
fly between these two base maps when you
hook up a switch to the MAP inputs. You can
use any open/close type switch. The polarity
of the wires is not important. When using the
Autotune kit one position will hold a base map
and the other position will let you activate the
learning mode. When the switch is “CLOSED”
Autotune will be activated. This feature is set
to Input 1 by default.
Shifter- (Input 1 or 2) These inputs are for use with the
Dynojet quickshifter. Insert the wires from the
Dynojet quickshifter into the SHIFTER inputs.
The polarity of the wires is not important. This
feature is set to Input 2 by default.
Speed- If your application has a speed sensor then
you can tap into the signal side of the sensor
and run a wire into this input. This will allow
you to calculate gear position in the Control
Center Software. Once gear position is
setup you can alter your map based on gear
position and setup gear dependent kill times
when using a quickshifter. Thru input 1 or 2
you can also setup a speed limiter that can be
activated thru a momentary switch.
Analog- This input is for a 0-5v signal such as
engine temp, boost, etc. Once this input
is established you can alter your fuel curve
based on this input in the control center
software.
Launch- The PCV allows you to setup a launch limiter
based on a grounding switch. With this
activated you can set a RPM limit when the
clutch is engaged.
ACCESSORY INPUTS
Wire connections:
To input wires into the PCV first remove the rubber
plug on the backside of the unit and loosen the
screw for the corresponding input. Using a 22-24
gauge wire strip about 10mm from its end. Push the
wire into the hole of the PCV until is stops and then
tighten the screw. Make sure to reinstall the rubber
plug.
NOTE: If you tin the wires with solder it will make
inserting them easier.
