+12V to Injectors Terminal
Connect this terminal to the wire that leads directly to the Fuel Injectors. The internal relay is rated
at 10 amps and this should not be exceeded. The FP50 uses a normally closed relay to operate
the vehicle’s injectors. If power to the FP50 is interrupted, the vehicle should default to petrol
operation.
OPERATION & ADJUSTMENTS
Green light – ACCEL TPS SET
The green ACCEL TPS SET light performs two functions;
A.
TPS SET Function FP50-DC & FP50-AC
- When the vehicle’s Throttle Position Sensor
(TPS) voltage is
below
the TPS/RPM SET potentiometer setting, the TPS SET light will
flash quickly (refer to the Adjustments & Tuning section). The vehicle is prevented from
changing over from petrol to gas when this light flashes quickly. When the accelerator is
held (steady) above the TPS SET position, the green light should remain off.
B.
TPS SET Function FP50-DS-SS
- When the vehicle’s incoming Throttle Position Sensor
(TPS) voltage is
below
the TPS/RPM SET potentiometer setting, the green TPS SET light
will flash quickly. This indicates that the CV30/CE30 stepper valve is being help open (ie the
processor is in Open Loop mode).
C.
ACCEL Function
- The green TPS SET light should come on when the accelerator is
depressed quickly. This indicates an increasing load condition to the processor. The
processor will now open the CV30/CE30 valve at a much faster rate to ensure adequate fuel
is delivered to the engine during acceleration. The green light will stay on for varying times
depending on how far and how fast the accelerator is depressed. It should however, go off
within 5 seconds after depressing the accelerator.
Lean & Rich Orange Lights
The left orange Lean light indicates when the engine is
running Lean
(ie not enough gas). The
right orange Rich light indicates when the engine is
running Rich
(ie too much gas). As long as
the gas mechanical delivery components (the convertor, vapor hose and mixer) can deliver
sufficient gas to the engine, these lights should flicker constantly (when the engine is above idle)
between rich and lean. This indicates that the Lambda (or stoichiometric) region is being
maintained. The exception to this is if the green acceleration light is on (in which case the rich light
should also remain on) and on the FP50-DS-SS model when Open Loop at idle is chosen.
Gas Light
The green Gas light comes on when the vehicle is operating on Gas (LPG-CNG).
Petrol Light
The red Petrol light comes on when the vehicle is operating on Petrol.
ADJUSTMENTS & TUNING THE GASTEC FP50 FUEL PROCESSOR
Note that clear (see-through) CV30/CE30 stepper valve cups are available so that
you can visually check the operation of the FP50 stepper valve.
1. Ensure that the CV30/CE30 stepper valve is fully open and its associated loom is
not
currently
connected to the FP50.
The stepper valve must not be connected until the initial setup
procedures below have been completed.
2. Turn on the ignition but
do not start the engine
. Ensure that the gas/petrol
switch is in the
gas position
.
