-The CP601 Fuel Processor is a closed loop processor requiring O2 and TPS sensor inputs.

-There is an adjustment for a closed loop software ‘mode’ at idle (enriches mixture when accelerating from idle) for CP601 and same adjustment for open loop at idle for CP601N

-The unit incorporates an indicator led (Red) to show when the mixture is Rich and Lean when off.

-A Green Led illuminates when a rapid increase in acceleration detected.

-The CP601 utilises a highly efficient stepper motor to control gas flow, also incorporating a brass adjuster for tuning.

-The Stepper motor operates in such a way as to continually give rapid adjustment of fuel mixtures under varying load conditions.  If there is an increase in load sensed via TPS it will operate at a much faster rate to give instant gas flow for high load conditions.

-Processor can be programmed for a specific purpose such as reverse TPS voltage, wider O2 signal band, specific fuelling trims for emission control etc. please enquire.

-Achieved Euro 2, 3 and 4 Pass. Contact for more info.

The CP342 Function Controller is an upgrade (more features) or replacement for the IMPCO IFC103A.

The CP342 features a dual pattern petrol start allowing for COLD and HOT petrol assist settings.

It also incorporates a ‘crank lock out’ facility in addition to internal relays for injector cut out, fuel pump isolation and fuel gauge interface. This unit is developed to provide Petrol Start Operation on Crank rather than Ignition.

CP201 – Air/Fuel Ratio Controller for American Systems

(To suit Air Valve type systems)

• The CP201 Fuel Processor offers accurate mixture control under all engine load conditions; this is done via the CP201-V Vacuum Valve which controls the operating pressure of the Convertor, in turn controlling fuel mixtures.
• The processor requires the connection of both the O2(Oxygen Sensor) and TPS(Throttle Position Sensor).
• The unit has an Open Loop at idle function (enriches mixtures at idle). This is adjustable and indicated by the Green Led (‘ON O/Loop’), when on Open Loop mode is activated.
• The engines air/fuel mixture is indicated with the Red and Blue Leds, the Red indicates a Rich mixture and Blue a Lean mixture.
• The unit recognizes rapid acceleration/high load conditions via the TPS and instantly enriches the engine mixtures eliminating any ‘Lean’ running condition. This is indicated via the Yellow Led (‘R/Rev’).
• The unit is water resistant, however it is recommended to mount the case inside the vehicle cabin.

CP401 – Microprocessor Controlled Emission Air/Fuel Ratio Controller for American Systems (To suit Air Valve type systems)

• The CP401 Fuel Processor offers extremely accurate mixture control under all engine load conditions.
• The processor requires the connection of both the O2(Oxygen Sensor) and TPS(Throttle Position Sensor).
• This unit has unique ‘software modes’ for different driving applications, sensed via the TPS Signal.
• The ‘modes’ are for idle, acceleration from idle, cruise, acceleration from cruise and deceleration.These software modes enable the vehicles engine to hold an ideal AIR/FUEL Ratio very efficiently. This in turn increases mixture control for drivability, power, fuel efficiency and most of all Clean Burning Emissions (**see notes below**)
• The unit has a specific idle software mode. This is adjustable and indicated by the Yellow Led (‘TPS On at idle’)
• The engines air/fuel mixture is indicated with the Red Led
• The unit recognizes rapid acceleration/high load conditions via the TPS and instantly enriches the engine mixtures eliminating any ‘Lean’ running condition, indicated via the Green Led (‘Accel. On’).
• The unit is water resistant, however it is recommended to mount the case inside the vehicle cabin.
• The processor incorporates a diagnostic function where if a problem is sensed eg. O2 sensor failure, wiring fault, air leak etc. the processor will go into a diagnostic mode and give a set duty cycle. The diagnostic mode will be indicated by the Red/Rich Led ‘blinking’ at a constant rate.

**Notes – This Fuel Processor has been labeled with ’Emission Controller’ as it has passed Euro 2 standards on a variety of vehicles with different types of Air Valve Systems or Negative Feed Systems, also a limited number of vehicles have obtained a Euro 3/4 pass.  This processor is highly efficient in holding ‘ideal’ (Stoichometric) Air/Fuel Ratio but requires all other factors to be operating efficiently.** 

CP401L (LBL Lean Bias Logic) – Microprocessor Controlled Emission Air/Fuel Ratio Controller for American Systems (To suit Air Valve Type System)

The new Lean Bias Logic (401 GAS) processor for use in automotive LPG systems controls in a completely different manner to the traditional method employed over the past 15 years.

If we consider how mixtures have been controlled in the past, a processor driving a valve (FCV) directs vacuum to the atmospheric port of the converter.

As the open time of the valve is increased (duty cycle) vacuum lifts the converter secondary diaphragm to close the secondary seat, leaning out the mixtures from the base rich setting. The problem with this type of control is that it actually works against the basic operation of the mixer / converter.

CP401L – Lean Bias Logic (LBL)

This system employs a reverse logic processor that drives the FCV. Fuel is added (via the FCV) from the secondary chamber of the converter to the top of the mixer air valve or into the air valve vacuum port (similar to a vacuum power valve VPV).

Instead of employing a RICH bias mixer (FB), the LBL system uses a lean bias mixer (CA), with at least one extra lean shim.  The base mixtures are set lean with sufficient fuel added to maintain 15.5 air fuel ratio (AFR). This eliminates the air valve vacuum being applied to the atmospheric port of the converter.

During acceleration (as the processor senses an increase in throttle position via the TPS), the fuel control valve will momentarily open to 60% duty cycle to further enrichen the mixtures.  This is achieved via two conditions:

1. Adding fuel into the air stream: and /or
2. As the FCV opens to 60% duty cycle on acceleration, air valve vacuum is ‘bled off’ the top of the mixer diaphragm allowing the metering spring to push the air valve assembly down. This increases air speed below the air valve, increasing air valve vacuum (depression) thus drawing more fuel (vapour) from the converter.

The mixer and converter are now able to operate as they were originally designed to with out restriction.

To correctly set up the system a Fuel System Analyser (DP400) or multimeter with a duty cycle function should be used. The processor has rich and lean LEDs to assist with set up, however the duty cycle is critical to satisfactory operation.

START UP FIXED DUTY CYCLE:

When the engine is started the processor will hold the Fuel Control Valve (FCV) at a fixed duty cycle of 40 until an increase in voltage is sensed from the 02.  This will stop ‘over fueling’ when the 02 is cold.

TPS ON AT IDLE AT IDLE:

The TPS on at idle feature (light on) changes the integration rate of the FCV at idle to reduce RPM ‘hunting’.

In addition the enrichment rate from is quicker with this feature enabled.

02 SENSOR MALFUNCTION FEATURE:

This feature will sense when the 02 sensor ceases to operate (fails to see the 02 sensor voltage change).  The processor will revert to a default FCV duty cycle of 40 and the RED LED will flash.

DP400 Combination Duty Cycle Meter and 02 Sensor Meter

In Automotive and electronics, the duty cycle is the fraction of time that a system is in an “active” state. Duty cycle is the proportion of time during which a component, device, or in LPG application, the 3 way valve found on ‘Air Valve Systems’ is On. This is displayed in Large Blue numerals on the DP400 in percentage terms of 0% – 99%.

The 02 Sensor operation is displayed on the above DP200
