Electronic Jet Kit Instructions

Kawasaki/Suzuki

Thank you for choosing the Techlusion Electronic Jet Kit, the TFI. The TFI is usable for sequential fuel injection 2 cylinder Kawasaki, Suzuki motorcycles **. ** Honda: 2010 Fury Kawasaki: 2006-09 Ninja 650R/ 2006-08 VN900/ 2004-08 VN2000 Suzuki: 2002-08 DL650, DL1000/ 2003-09 SV650, SV1000/ 1997-2003 TL1000/ 2006-09 M109R Photo installs for many applications are available at www.dobeckperformance.com in the support forum. This product is a great fit for stock bikes with exhaust and intake mods. It is also capable of handling the fuel needs of big bore kits, light cams, and a variety of head porting. This is an Electronic Jet Kit. Like jet kits in the past, the more you modify, the more responsibility you take in getting your fuel curve right. Going to www.dobeckperformance.com will help you obtain better high horsepower tuning.
Note: If your model is equipped with a 02 sensor in the exhaust, you will need to disable it or leave the first dial (green) at the 1:00 oclock position. Any questions call tech support @ 877-764-3337
Due to the complexity of the newer motorcycles, dealer install may be required. Call for more details for installation or visit www.dobeckperformance.com for photo installs.
INSTALLATION PREP Install Time: 30 minutes Required Tools for: Disconnecting the negative terminal of the battery Removing your seat, side cover and/or tail section. Small screwdriver for TFI adjustment.

INSTALLATION (For any and all help during install or tuning please call us(8-5M.T. m-f), we cant help if you dont call) 1. Before installing the TFI you must first disconnect the negative lead from the battery. 2. Determine a location for the TFI unit. Suggested locations are as follows: Under the seat, behind a side cover or tail section. 3. The TFI comes with a harness with injector connectors that match the factory injector connectors. 4. Locate the factory fuel injectors (see owners manual if you are not sure)*. *: Some models are equipped with two sets of injectors (primary and secondary) the unit is designed to interface with the primary injectors. If the TFI harness does not match your injectors do not proceed and call tech support at 877-764-3337.
5. Disconnect the factory injector connectors from the fuel injectors and replace with the TFI injector
connectors from the TFI unit, basically unhook the factory injector connector and plug the matching TFI connector (female) to the injector and then connect the factory injector connector to the TFI connector that simulates the injector (male). There is no order to hook up the TFI harness to
the factory harness just make sure the original factory connector goes to its original cylinder. It is a good idea to make sure there is a little slack in the harness to prevent engine vibration from damaging/breaking a wire on the connectors. 6. Be sure to check the wires are not in direct contact with any sharp edges, exhaust and/or other
objects that could result in long term wearing and/or damage. 7. Connect the TFI ground lead to the negative terminal of the battery along with the factory ground lead. 8. With the rubber plug removed from the TFI, turn the motorcycle key switch to the ON position. As the bikes electrical system goes through initial start up mode you may see LEDs flashing on the TFI. 9. Start the motorcycle. The TFI is programmed not to add fuel at idle. This may cause all the LEDs to flash at idle, this is normal. Some models may have a solid green LED at idle, this is also normal. If just the green or red LEDs flash after startup or no LEDs are visible or bike doesnt start, please confirm/retry all connections. If still a problem call tech support at 877-764-3337.

Electronic Jet Kit Instructions Tuning
(For any and all help during install or tuning please call us(8-5M.T. m-f), we cant help if you dont call) Green LED pot(1st): Air fuel mixture screw adjustment. With TFI installed and the bike fully warmed up, screwdriver in hand, locate the green LED and the pot right below it. Using the throttle raise the RPM to a high idle or about 2000-RPM. Once there, slowly turn the green pot clockwise from the 1:00 position (off) until you achieve the highest RPM and smoothest running sound (like a mixture screw on a carburetor). You should find the best setting between 2:30 and 4:00 oclock. If you turn the green pot clockwise and the engine does not accept any more fuel (RPMs drop when adding fuel) you may have one or more of these problems (See troubleshooting Motorcycle). Yellow LED pot(2nd): Acceleration fuel adjustment (bottom to mid range fuel). Anytime the yellow LED is on, this pot is adding fuel. In neutral raise the RPM slowly up through the mid range and see no yellow LED. However, opening the throttle quickly from idle you should see the yellow LED come on. Fine tuning: Start with the suggested setting and then add clock position at a time until the bike says too much (hesitation) then back off 1 clock position, if worse go opposite direction. If no yellow LED there is not enough load to turn it on. At that point the street or dyno will be able to show the difference. The yellow pot adds its fuel below 70% of maximum RPM. Red LED pot(3rd): Main jet fuel adjustment (top end fuel). It adds about 2.5 points of main jet fuel with every clock position. For example, one clock position is the same as 150 to 152.5 main jets. Fine tuning: Start with the suggested setting and then add clock position at a time until the bike says too much (hesitation) then back off 1 clock position, if worse go opposite direction. The red pot adds its fuel above 70% of maximum RPM. RPM pot(4th): All V-twins. Sets the RPM that the red pot fuel (main jet fuel) turns on. One clock position is roughly 1000 RPM. This pot should be set to about 70% of redline. (For example: Suzuki M109R redlines at 5800 RPM and 4000 is roughly 70% of redline which would be 4:00 oclock). On some dual plug systems (Kawasaki, Suzuki) you will need to double the RPM clock position to have the same results. Verify setting by raising the RPM in neutral, look for green and yellow LED to shut off and the red LED to turn on at the chosen RPM or refer to suggested settings if you have no tachometer.

TROUBLESHOOTING

(For any and all help during install or tuning please call us(8-5M.T. m-f), we cant help if you dont call) Motorcycle Fuel injected bikes all have the same exact fuel curve and is corrected everyday by the on board weather station. Nothing is leaner than a stock fuel injection map. So with our box on and the bike fully warmed up, if you slowly turn on the green pot and the engine does not accept any more fuel (RPM drops when adding fuel) then you may have one or more of these problems. (Order from most common to least common) 1. Engine not fully warmed up. 2. A vacuum leak on the intake. 3. High lift cams affecting map at light loads and low RPM. 4. Cylinder head temp sensor malfunction. 5. Loss of TPS and ECU sync.
POOR MILEAGE Solution: 1. Check your green pot setting. This setting is generally responsible for 90% of your mileage. In the hundreds of installs performed, we have never gone beyond the 4:00 setting. Try backing down the green setting slightly. You can slightly lower the yellow and red settings also. 2. RPM pot adjusted too low**. Make sure the red LED is turning on no lower than 70-75% of the maximum rpm. 3. Make sure your engine passes the 2000-RPM test at the beginning of the troubleshooting chapter. If you still have mileage issues call tech support at 877-764-3337 **: Some engine setups can dictate a higher or lower setting on the RPM pot.
