Controls
The FI Controller is preprogrammed with 4 base fuel
curves. The curves are selected using the switch
labeled BASE. These curves adjust fuel delivery
based on throttle position and RPM, providing the
right amount of fuel under all conditions. The 4 fuel
curves correspond to varying levels of performance
modifications. The levels of modification are broken
down into the following groups.
Base Curve 1 -
Slipon exhaust or full exhaust. No
crossover pipes, Stock crossovers removed. Stock or
aftermarket air filter. Stock ECU.
Base Curve 2
- Slipon exhaust or full exhaust. Stock
or aftermarket crossover pipes. Stock or aftermarket
air filter. Stock ECU.
Base Curve 3
- Engine mods(big bore kits, cams).
Full exhaust systems and aftermarket air filters. Stock
ECU.
The fourth curve has all of the fuel adjustment values
zeroed out. This curve is selected by moving the
rotary switch to any position other than Base 1, Base
2 or Base 3. This curve is useful for those wanting to
just modify the fuel delivery with the potentiometer
adjustment, without having any other adjustments.
In addition to the 4 curves, there are 3 potentiometers
that allow you to fine tune the curve you select. These
potentiometers allow you to adjust the fuel curve from
+20% to -20% in 3 different RPM ranges. The RPM
ranges are:
LOW
Idle - 3000 RPM
MID
3000 - 6000 RPM
HIGH
6000 - 9000 RPM
To add fuel, turn the potentiometer clockwise. To
subtract fuel, turn the potentiometer counterclockwise.
With the potentiometer pointed straight up at the thick
tick mark (towards the Dynatek logo), that is 0%
adjustment. Fully counterclockwise is -20%, and fully
clockwise is +20%. Adjusting the potentiometer
between these points will result in adding or subtracting
an amount of fuel proportional to how far the knob
was moved from zero.
Calibration
To select the right curve, start by making sure that all
3 of the RPM pots are set to zero adjustment. Then
select the base curve which corresponds to the bikes
level of modification. This should make the bike run
better at all RPMs. The AF ratio if measured on a
dyno should be much smoother throughout the RPM
range than without the FI Controller. If it feels worse
or the AF ratio gets too lean at any RPM compared to
stock, try a different curve.
Once you have selected the correct curve, then you
can fine tune any problems with the map by using the
potentiometers. With the arrows on the pot straight up
and down, the pots are at 0% adjustment. To add
more fuel, turn the pots clockwise. To subtract fuel,
turn the pots counterclockwise. Do not attempt to
adjust while riding!
To compensate for stage 1 ECU, use the RPM based
pots. Lean out the LOW and MID by 5%-10%.
Troubleshooting
If the STATUS LED does not come on when the
ignition is switched on, there is no power to the FI
Controller. Make sure that you have the ground
hooked up properly either directly to the battery
ground, or to a lug on the frame that is grounded.
If the LED comes on, but does not run on one or both
cylinders, double check all connections at the injector,
making sure the connectors are seated properly.
