16.8 Shift Light Illumination (SL)
The F10 can be used to activate a shift light or a piezo buzzer when engin e sp eed exceeds the
programmed activation speed.
To use the shift light function, you will need the following:
A dashboard lamp or buzzer;
F10 programming software and cab le.
The lamp or buzzer should be wired to +12V on one side, and the other to the ECU. The lamp
used must not draw more than 0.5 amp of current (i.e. a 6 Watt globe). Alternatively, a high
intensity LED may be used. If so, use a series resistor of 330 ohms to limit the current through
the LED to around 40mA.
Once the wiring has been installed, run the F10 p rogrammin g software and go to the Op tions
page. Select the Shift Light function on the appropriate output and set the value as desired.
16.9 Auxiliary Fuel Pump (AP)
Running two fuels pumps continuously, or else a single very large flow-rate pump (if one is
available) means excessive no ise and heating of the fuel. A street vehicle with very high
potential outp ut will not need a lar ge fu el supply at all times. The second pump would only be
activated when load demands require that the extra flow be availab le.
Note: The extra fuel pump cannot be driven directly by the ECU. The ECU can
be made to drive a relay to power the pump.
To use the Auxiliary Fuel Pump function, you must have the following:
A properly plumbed fuel pump, wired through a relay;
F10 programming software and cab le.
The extra pump must be connected in parallel with the primary fuel pump. Figure 16.9
suggests a possible lay out. The check valve is necessary to p revent fuel from being forced in
the wrong direction. Connect the power to the pump via a relay as shown. Either the positive
or negative side may be switched through the relay.
Run the F10 p rogrammin g software ONLINE and select the Auxiliary Fuel Pump function on
the approp riate outp ut. There are two p arameters that define when the Auxiliary Pump will be
switched on.
Loa d Bar
This is the bar numb er on the fuel maps which must be exceed ed for the extra fuel
pump to be switched on. If y ou wish to switch the extra fuel p ump only by engine
speed, set this to 32.
Engi ne S pee d
The extra fuel p ump will turn on when the engine sp eed exceeds this p arameter. If you
wish to switch the pump only by load, set this parameter high.
