User manual DYNATEK DFCH-3

[. . . ] The tank needs to be raised enough to give access to the fuel injectors and TPS wires. STEP 1 Rear Cylinder Injector Front Cylinder Injector STEP 2 Unplug the front injector. On the FI Controller, there are 2 pairs of injector connectors. [. . . ] 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 - Stock or basic modifications. This includes slip on exhausts, intakes, air boxes, and air filters. 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 MID HIGH Idle - 2000 RPM 2000 - 4000 RPM 4000 - 6000 RPM Calibration To select the right curve, start by making sure that all 3 of the RPM pots are set to zero adjustment. [. . . ] 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. [. . . ]
