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.
CAM FUEL CONTROLLERgizzmo
DotMatrix LED’s display your real-time Tachometer in all lighting conditions whilst having a high resistance to heat and vibration.
Gizzmo’s CamFC is over engineered with a 40mhz RISC Processor capable of processing 10,000,000 instructions a second.
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 so deceptively small, you can mount it virtually anywhere.

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 techni-cian 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.

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.

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.
+ Solenoid / – Solenoid:
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 +SOLselection on the CamFC would output a positive signal to the VTEC or positive triggered accessory whilst the –SOL 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 someresearch prior to instillation 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.

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 acces-sory 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.

gizzmoELECTRONICS
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: The tachometer on my CamFc does not line up with 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.
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.
Trouble Shooting I
23
gizzmoELECTRONICS
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 tachom- eter 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: 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.
Trouble Shooting II
24
gizzmoELECTRONICS
Symptom: Vehicle losses 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: Vehicles 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.
Trouble Shooting III
25
gizzmoELECTRONICS
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 low cam fuel tune. Because of this, you most likely will have to alter the AFC points at 4500rpm and 5000rpm to offset the tune to fall more in line with Hi cam tune.
What does A/F OFFSET mean?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 negtive 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.
