CAN LINK
:
This connects to the CAN LINK connection on your FAST™ XFI™ Main Harness. Both the XIM™
and the XFI™ Harness will have a pair of CAN connectors. The plug from one harness will connect to
the receptacle from the other harness. It does not matter which pair of connectors is used as long as one
pair is mated. This connection can be made through an Interconnect Cable(s) for additional reach.
There will be one loose plug and one loose receptacle at either end of the CAN wiring. These loose
ends need to be capped off with a Terminating Plug at one end and a Terminating Receptacle at the
other. This is absolutely necessary for proper network performance. The XFI™ uses the CAN Link to
tell the XIM™ what timing values are called for in the tuning file.
Warning:
Before starting your engine, make sure that with the ignition switch on, the “Status” light on
the XIM™ is illuminated. This indicates that the XIM™ and XFI™ are communicating properly via
the CAN network.
Running the engine without proper CAN communication can result in permanent damage to the
XIM™ and ignition coils.
If the “Status” light is not illuminated, check the following items:
•
Verify that the CAN wiring is connected per the provided instructions. One male or female
connector from the XFI™ should be connected to a mating connector on the XIM™. The
unused male and female connector must have the terminating resistors plugged into them.
•
Verify that the CAN retro-fit kit wires are plugged into the Blue XFI™ main connector as
follows: Green wire to pin C26 and the Yellow wire to pin C25.
•
Verify that in the C-Com® software for the XFI™, under “Operational Parameters”, IPU
Ignition is selected.
•
Verify that under “System Configuration”, CAN Stream is enabled.
•
Verify that the XIM™ wire labeled 12V is connected to a 12V source that has power when the
switch is in the run position and during cranking.
•
If after checking all of these items, you still cannot get a status light on the XIM™, call the
FAST™ EFI HELP™ line at 1-877-334-8355 for assistance before starting your engine.
CALPORT
:
This connector does not connect to anything during normal operation of the XIM™ unit. It is only used
when ‘flashing’ your XIM™ unit when there is an update available. See ‘Flashing your XIM™’.
FLASH
:
This is a loose wire that does not connect to anything during normal operation of the XIM™ unit. It is
only used when ‘flashing’ your XIM™ unit when there is an update available. See ‘Flashing your
XIM™’.
+12V SW
:
This wire needs to be connected to a ‘switched’ power source, or in other words, a power source that is
hot whenever the engine is cranking or running. This is the wire the turns the XIM™ on and off.
+BAT
:
This wire needs to go directly to your positive post of your vehicle’s battery.
-BAT/-BAT(AGND)/-BAT(DGND)/-BAT(PGND)
:
Any of these that are present in the harness go to the negative post of your vehicle’s battery.
