Read all instructions carefully and completely before installing your new Fi2000CL module. It is
recommended that a qualified mechanic or technician install this product.
1. Remove the seat, and air cleaner assembly, remove both front and rear gas tank mounting bolts. Prop the
rear of the gas tank up approximately 2”-4" with a small block.
2. Remove left side cover by pressing plastic tab upward and pulling bottom of steel cover outward and up to
release from upper retaining tabs, see Figure 1.
3. Pull engine ECU outward by releasing from retaining tab to allow for Fi2000 wire harness installation, Figure 2.
4. Pull existing wire harnesses out from under the seat frame area. Place the Fi2000 tuner and harness in the
area which is under the seat, see Figure 3. Route the two longer Fi2000 harnesses through the left side
cover area where the ECU was pulled out, see Figure 2, and continue routing both through the hole at the
front of the left side cover inner housing, be sure to REVIEW in Figure 2! The longest harness must be
routed to the right side of the motorcycle next to the starter, and ground lug on case. The other harness will
go to the injectors. Once harnesses have been pulled into place, be sure to reinstall engine ECU back into
place, being sure none of the harnesses get stuck on the other electrical components, it must snap back into
place under the tab.
5. Route the injector harness to the front and rear fuel injectors located between the cylinder heads, along the
right side of the upper frame backbone. Place the harness in the plastic harness channel provided along
the frame. Locate the factory connector on each fuel injector. Depress the clip on the connector and pull the
connector free and move it out of the way. Note: A pair of needle nose pliers and a long flat blade
screwdriver helps with this job. Attach the pair of Fi2000 module’s injector connectors labeled "FRONT" to
the front injector. Take the original HD connector and insert the corresponding Fi2000 connector into it, refer
to Figure 4.
6. Attach the Fi2000 module’s remaining injector connectors labeled "REAR" onto the rear injector. Then take
the original HD connector and insert the corresponding Fi2000 connector into it, refer to Figure 4. Secure
the Fi2000 injector harness to one of the existing HD harnesses, at the front of the plastic harness tray,
along the frame rail, under the tank, using the supplied 4" zip tie.
7. Remove right side cover by removing Phillips screw at bottom of cover and lifting bottom of cover outward
and up to release from upper tabs. Route the black ground wire from the Fi2000 through the gap just under
the frame and to the rear of the battery box. Attach the ring terminal to the negative post of the battery.
8. Route the longest Fi2000 oxygen sensor harness from rear of engine area to below battery and next to
starter. Remove the nut securing ground wire and pull off ground wire to allow connectors to pass through
between rear of transmission case and harness sheath in front of swingarm, see Figure 5. Reinstall nut
securely!

9. Continue routing connectors and harness forward along lower right frame rail, be sure to keep clear of
brake rod and linkage. Route forward to voltage regulator. Remove the two Allen bolts holding the voltage
regulator onto the lower front frame, see Figure 6. Let it drop down, then directly behind that is a black
plastic panel. Hinge that panel down to access the plugs behind it. Locate the front oxygen sensor
connection, slide it off its holding pin and unplug the connector. Plug the Fi2000 O2sensor harness male
connector into the O2sensor female connector and slide them back onto stock plastic panel location. Mate
the stock male harness connector with the female Fi2000 connector, place this set of connectors between
connectors attached to plastic panel, be sure Fi2000 harness exits on the right side between panel and
frame. Reinstall the panel and the voltage regulator. Leave a small amount of slack in harness at
connector and zip tie along lower right frame rail in 3 locations.
10. Locate the black waterproof connector in the wire harness bundle that was tucked down into the open area
under the seat, see Figure 3. Unplug the female connector that comes from the rear oxygen sensor, and
mate it with the male connector from the shorter Fi2000 O2 sensor harness. Mate the stock male connector
with the female Fi2000 connector. Be sure connectors are fully seated.
11. Remove the block propping up the fuel tank and lower fuel tank back into proper position.
12. Before reinstalling the fuel tank bolts and the seat, verify your connections. Remove the door from the
Fi2000 box to expose the LED’s. The pot settings on the Fi2000 must be set to match the proper intake
and exhaust configuration, Refer to Figure 7 and the Advanced Tuning section below to determine the
proper configuration. Verify the wire connections by (1) turning the ignition on, prior to starting, and see if
all three LED’s are on steady. If you have no light, your ground connection (BLACK wire) has not made
proper contact or the injector connections are not complete. (2) After achieving a steady light from all three
LED’s, start the motorcycle, wait 15 seconds and let it idle, the green light should now be the only LED on.
If all three LED’s are still on after start up verify you have attached the injector connectors correctly.
Reattach the door when finished. Note: Make sure the ignition is turned off before changing any
connection.
13. Remove the backing from the Velcro and attach the Velcro pad down between the back of the battery and
the ECU on the flat area of the frame. Apply the mating Velcro to the back of the Fi2000 and attach, see
Figure 3.
14. Reinstall the right side cover. Be sure the Phillips screw is properly secured. Reinstall left side cover and
be sure that it is properly secured by the tab which keeps it in place. Reinstall fuel tank bolts.
15. Reinstall seat and air cleaner. Secure any fasteners loosened during assembly.
ADVANCED TUNING
Your Cobra® Fi2000 fuel injection module has been tested and preset for best function and rideabilty on a
motorcycle with stock air cleaner and Cobra slip-on mufflers. The Fi2000 does have 3 important adjustments
that allow you to tune the module for optimum performance, especially if you have performed other changes
to your motorcycle. These adjustments also allow you to resolve drivability issues if our stock settings are not
exactly right for your bike. Make sure your motorcycle is up to normal operating temperature (15 minutes of
riding should be sufficient) before making any adjustments.
GREEN LED POT (left pot) –With the Closed Loop function of this module you do not need to adjust this
setting, leave it at 2.0. Without a closed loop system this adjustment would affect idle and cruise fuel. If you
had cruising issues, this is where you would try a different setting. Generally, surging and uneven running
while cruising is a lean fuel condition, so adding a small increase in fuel by turning this adjustment
clockwise with a small flat blade screwdriver a 1/2 of a position would help. The bike would need to be Test-
driven to feel an improvement and only the setting would need to be increased until the surge went
away. Also, backfiring or popping on trailing throttle is generally a lean symptom (or an exhaust gasket leak).
The same small increases as above would be tried just until the backfiring would disappear.

ADVANCED TUNING CONTINUED
YELLOW LED POT (middle pot) - this adjustment affects acceleration and power fuel. If you have a hesitation or
bogging on acceleration, this is where you would try a different setting. Aftermarket air cleaner assemblies generally
lean out fuel mixtures, so try small clockwise increases as above until a smooth acceleration returns.
RED LED POT (right pot) - this adjustment is the top end or power fuel adjustment. Just like the main jet in a
carburetor, it starts to control fuel as you demand maximum power from your bike and takes over completely above
4000 R.P.M. As performance gains are added to your motorcycle, such as big bore kits, camshafts, flowed cylinder
heads, etc., each component will increase the fuel demand of the system. With the red pot turned to its maximum
(10) position, the Fi2000 will cope with nearly 100 R.W. horsepower. You can generally, if you are using quality
performance engine upgrades, in a sensible combination equate the numbers evenly from 2 up to 10 based on
horsepower gains.
TUNING NOTES
Typically our 2 into 1 and speedster exhaust systems require one additional increase, on the yellow and red pots,
over slip-ons or staggered duals. On high performance motors, slip-on mufflers do not flow well enough and create
fuel setting problems and detonation. Cobra recommends the installation of any of its complete exhaust systems.
These settings have been tested for stock motorcycles that have popular aftermarket slip-on exhaust systems
installed. This Fi2000 will also work in combination with a Cobra® PowrFlo™ Air Intake System and various
complete exhaust systems, please visit www.cobrausa.com for system details.
TROUBLE SHOOTING: If you have any problems refer to Step 12 in the main body of the instructions.
