CAM FUEL CONTROLLER
The CamFC has an AFC (air/fuel controller) onboard so that the
fundamental fuelling issues related to the addition of tuning
accessories such as extractors, exhausts, adjustable cam gears,
filters and mild cams can be resolved. The Cam switching point is
adjustable in 1 RPM increments and the switch off point is
adjustable as well.
The AFC is adjustable in 500rpm increments and automatically
interpolates (averages) between these points. For non-adjustable
cam vehicles, the CamFC can be used for its AFC and tachometer
features whilst the cam trigger output can be used as an RPM
switch for NOS, shiftlight, high boost solenoid etc.

capable of processing 10,000,000
instructions a second.
Extruded Aluminium Case
By utilising a rugged Extruded
Aluminium case you can be assured
that your CamFC will keep its look for
years to come. Because the CamFC is

Quick Start
Obtain ECU wiring schematic. We have supplied what we have available
at the back of this booklet and our latest listings are available at
www.gizzmoelectronics.com. If your vehicle is not covered, your technician should be able to source the information pertaining to your vehicle.
Disconnect the negative battery terminal
Wire the CamFC’s positive wire to the Engine ECU’s ignition positive wire
Wire the CamFC’s negative wire to the Engine ECU’s earth wire
Wire the CamFC’s RPM wire to the ECU’s Tachometer output, igniter
output or digital crank/cam angle sensor.
If utilising the AFC feature, cut the wire for the main load sensor (flow
meter/map sensor etc) and wire in the CamFC’s AFC IN wire to the cut
wire on the flow meter side. After this wire the AFC OUT to the other cut
wire on the ECU side.
If using the CamFC’s cam functions, cut the cam actuator wire from the
ECU and wire the CamFC’s CAM OUT wire to the actuator side (engine
side), NOT the ECU side. If fitting the CamFC to a Vtec, wire the
CamFC’s CAM IN wire to the cut wire on the ECU’s side.
If fitting the CamFC to a Vtec that has a VTM wire (most Type R’s and
some SOHC Vtec’s do not have these), cut the ECU’s VTM wire and
connect the CamFC’s VTM OUT wire to the ECU side of the cut wire.
Check over all the wiring and if everything is OK reconnect the battery
terminal.
Turn the ignition on and configure the SOL (Solenoid) and the SENS
(Sensor) function on the CamFC.
Start the vehicle and configure the INPT (Input) function on the CamFC
to calibrate the tachometer on the CamFC to the vehicles tachometer.

A/F OFFSET
A/F offset on an AFC represents the percentage offset to
the input voltage. So, for example, if the voltage from
the flow meter / map sensor was 2.0 volts and the AFC
was set to +10%, the output voltage would be 2.2 volts.

The INPUT mode is where you align the Engine RPM to the CamFC’s RPM
(you may consider it a cylinder selection mode), a tachometer may offer
some assistance in this mode. There are 8 preset options labeled from A to
H and in order to set the input mode, the vehicle must be running. Upon
entering this mode the display will oscillate between the option that is
presently set (A to H) and the RPM that will be displayed for that option.
Having entered the input mode, the up and down buttons rotate through
the options. Once you have navigated to the option that displays an RPM
that most accurately lines up with the engine/tachometer you can exit the
input mode and the option will be automatically saved to memory.

Rise/Fall Definition
95% of cars have what we define
as ‘rising’ type load sensors. A
rising type load sensor has an
output voltage that rises with load.
This means that when the vehicle is
under high loads the voltage output
from the sensor will be higher than
when it is under slight loads. A fall
sensor is the inverse of this e.g.
slight loads output a higher voltage
than high loads. Defining if your
vehicle has a rise or fall type
sensor is the job of an experienced
technician but this feature will in no
way impact the operation of your
vehicle and is only present to align
the polarity of the AFC settings.

Tech Notes
INPUT menu:
Different engines have different frequencies on the tachometer
& cam/crank angle signal wires and therefore we must
calibrate the CamFC to suit their frequency. Do be aware
that the CamFC may not line up perfectly with an analogue
tachometer due to the inaccuracy of analogue Tachometers
but it should be clear which selection is correct as they should
be within +/- 300rpm.
+ ON / – ON:
Mivec’s require a negative signal to switch on, whilst Vtecs
require a positive signal. The CamFC can therefore adapt to
both these requirements. In the applications above, the +NO
selection on the CamFC would output a positive signal to the
VTEC or positive triggered accessory whilst the –NO would
output a negative signal to a MIVEC or negative triggered
accessory.
Frequency Type Flow / Pressure Sensor:
Some load sensors output a frequency relative to flow whilst
others output a voltage relative to flow / vacuum / pressure.
Due to the variety of vehicles we recommend doing some
research prior to installation as to whether you have a
frequency or voltage type sensor. We have neither heard of or
experienced any damage due to an incorrect selection and
believe it to be near impossible to happen.

Wiring Diagram II
RED, 12V Power Supply: This must be soldered to a clean 12V
ignition power source, preferably the ECU power source.
BLACK, Earth: Solder this to the ECU’s earth supply.
GREEN, RPM in: Solder this wire to a low voltage digital engine
frequency signal wire e.g. Igniter trigger signal, digital crank/cam angle
sensor, ECU tach out signal. DO NOT join this wire to the coil negative
wire or a Tachometer wire that does not come from the ECU.
BROWN, VTM: On VTEC’s this wire must be connected to the oil
pressure switch wire that returns to the ECU. In VTEC applications, be
aware that not all VTEC’s have a VTM wire, ESP Type R’s an SOHC
VTECs.
WHITE, AFC Signal in: After cutting the load signal wire to the ECU,
solder this wire to the Sensor side.
YELLOW, AFC Signal out: Solder this wire to the ECU side of the cut
Sensor wire.
PURPLE, VTEC in(ECU side): On VTECs this must be soldered to the
ECU Side of the cut cam solenoid wire.
BLUE, AUX out / Vtec out: this wire is to be connected to the accessory
that you wish to run. This has a maximum output current of 1.5 amps,
beyond this, a relay must be used. For VTEC/MIVEC usage, the cam
solenoid wire from the ECU must be cut before soldering the CamFC’s
Aux out wire to the solenoid side of the cut wire.

Trouble Shooting I
Symptom: My car starts but does not run properly
•
•
•
Check that the AFC is set at zero throughout the rev range
Check that you have the ‘SENS’ mode set correctly for
your vehicle
If in doubt, disconnect the AFC in and out wires and
connect the two vehicle side wires back together as
factory to see if it operates correctly. If this is successful
there is either an incorrect setting in the CamFC, or it is
defective.
Symptom: My checklight stays on since fitting the CamFC
•
•
•
Some vehicles can be sensitive to the amount of
adjustment that the AFC has, try setting it at 0% right
through the rev range and see if this corrects it.
If a vtec, check that you have connected the VTM wire
where appropriate.
If a Vtec, check that the VTEC IN wire is connected.
Symptom: When I increase my AFC setting my car
detonates/leans out
•
Check that the RISE/FALL setting selected after setting
VOLT within the sensor setup menu is correctly set for your
vehicle
Symptom: The CamFC does not power up
•
•
Recheck the power and earth connections by probing the
CamFC wires with a tungsten, not LED, test light.
Is your vehicle 12 volt and not 24 volt? If your vehicle is
24V the CamFC may have been damaged.
22

ELECTRONICS
Trouble Shooting II
Symptom: There is no tachometer reading when the
engine is running
•
Check that the RPM wire on the CamFC is connected to a low
voltage DIGITAL rpm source e.g. ECU tachometer output,
igniter trigger, digital crank angle sensor output and NOT a
coil negative, analogue crank angle sensor (reluctor, inductive
type) or tachometer signal from a coil negative source.
Symptom: The cam actuator/aux is not switching on

Check if the ‘SOL’ mode is set correctly. ‘+ON’ is for a
solenoid or lamp etc that has a permanent negative and
requires a positive supply from the CamFC in order to
operate. The ‘-ON’ is the inverse of this.
If a VTEC vehicle, is the VTEC IN & VTEC OUT around
the correct way?
Symptom: The tachometer on my CamFC does not line up
with my vehicles tachometer

•
Check that the ‘INPT’ mode on the CamFC is set correctly.
Factory tachometers can be up to 600rpm out at higher
revs but should be within 300rpm at lower revs so it may
never quite line up with the CamFC. The CamFC is accu
rate to within 1rpm at any revs.
Check that the RPM wire on the CamFC is connected to a low
voltage digital rpm source e.g. ECU tachometer output, igniter
trigger, digital crank angle sensor output and NOT a coil
negative or tachometer signal from a coil negative source.

Trouble Shooting III
Symptom: Vehicle looses power just before/after switching
on vtec.
•
Chances are the cam is switching at the wrong RPM. A
lot of people believe that switching the cam on earlier
will result in getting their power earlier; this is not
always the case as sometimes the cam point should be
set later. There is an ideal switching point and the only
way to truly find this is quite often to set this cam point
on a dynamometer.
Symptom: Vehicle has lost power everywhere.
•
Check to see that the AFC setting (percentage offsets)
are zeroed out and that the sensor type is set correctly.
Check the location of the CamFC’s earth wire.
Due to these instructions being specific to the CamFC we do
not cover Auto Electrical principals in depth, and as stated
earlier, recommend this product be fitted by a qualified Auto
Electrician. Should your technician be experiencing any
difficulties we will endeavor to help to the best of our
abilities. Because we believe that this should be fitted
by a qualified technician due to its complexity, we will
be inclined to only assist technicians and therefore will
not offer telephone, literature or email support to
non-trade sources. Please remember, this is a highly
technical and complex device and a little mistake can
damage a very costly ECU or CamFC.

FAQ
Why is the Off Cam Setting automatically defaulted to
100RPM below the On Cam setting?
If you had your Cam point set to switch on just above 4500rpm and
off at 4500rpm and you were driving along at 4500rpm, the valve
would be erratically flicking on and off and your engine would not
know if it was coming or going as the cams would be switching
erratically.
Why do we need to change AFC setting, when we change our
cam switching point?
When changing a cam switching point, the original ECU is
unaware that this point has changed. Because of this it does not
alter the tune and therefore, if you have raised the high cam point
from 4500rpm to 5000rpm; at 4800rpm it will still have the high
cam fuel tune. Because of this, you most likely will have to alter the
AFC point at 4500rpm to offset the tune to fall more in line with low
cam tune.
What does A/F offset percentage represent?
A/F offset on an AFC represents the percentage offset to the input
voltage. So, for example, if the voltage from the flow meter / map
sensor was 2.0 volts and the AFC was set to +10%, the output
voltage would be 2.2 volts.
How come when I run larger injectors and high negative
numbers in my AFC my engine detonates?
When you lean the mixture with an AFC you are telling to original
ECU that it has less load so put in less fuel. As a consequence of
this, the ECU puts in more timing. If running larger injectors, we
recommend running injectors that are not much larger then factory.
