MORE POWER AND MORE TORQUE WITH THE USE OF THE POWER BOOST VALVE AND THE AIR/FUEL CALIBRATOR!

 

" Rising Fuel Pressure Regulator"
(Power boost valve)

Applicable on normally aspirated engines and on turbo engines

Most of the fuel injected engines suffer a common problem: they run lean under full load operation. If we attempt to obtain a more adequate mixture, usually we have an over rich idle. Replacing the original device with our "RISING RATE" regulator, will supply more fuel at the top-end, without causing an overrich mixture at the lower/power range.Resulting in quicker accelleration and throttle response without affecting your gas mileage.Overcomes flat spots, eliminates loss of power, up-to 18% of power increase if installed together with  Pipercross Induction High Performance Filter and Torque Master Ultra Performance Spark Plugs.

 

 

More information on How To install our Special POWER BOOST VALVE

  1. Before disconnecting the stock fuel pressure regulator you should
    measure the stock pressure at idle (usually it is about 2,5bar).

    Install our adaptor in the hole left by the removal of the stock fuel
    pressure regulator.

    Install our Fuel Pressure Valve in the engine bay (not too far from
    where it was the stock fuel pressure regulator) by using the fixing plate with
    the two holes.

    Connect (by using a suitable fuel  tubing) our adaptor to one of the
    two horizontal outlet holes of our POWER BOOST valve with the threaded
    connections supplied.Close the outlet hole remained opened by using
    the supplied conical tap.Lock firmly by putting LOCTITE 243 or similar on
    threadings and clamps.

    Connect the stock  fuel return tube to tank to the lower vertical
    connection of our POWER BOOST valve.Lock firmly by putting LOCTITE 243 or similar
    on threadings and clamp.If stock return is from fuel rail close the hole remained opened by putting a suitable cover tap.

    Connect the stock 5mm diameter vacuum  tube to the upper connection of
    our POWER BOOST valve.

     Install a fuel pressure gauge between our adaptor and our POWER BOOST
    valve by using a "T" connection.

    Unscrew the bolt located close to the vacuum tubing and loosen the
    lower nut.Switch on the engine and and keep it at idle.Set our POWER BOOST
    valve (by using the setting screw)  at about 10% more of the idle stock fuel
    pressure.For example from 2,5 bar to 2,7/2,8 bar.

    Tight nut and bolt and remove fuel pressure gauge.

    Our POWER BOOST valve is now ready to give you automatically a
    stronge fuel pressure for much better Torque and Acceleration.

MAKE YOUR PERSONAL AIR/FUEL ADJUSTMENTS AND GAIN UP TO 20% OF ENGINE POWER  - NEW FOR U.S.A. Easy to install -Instructions Included

The module provides precise adjustment of Air/Fuel Calibrator Ratio over the entire operating range of an internal combustion engine. It is especially useful to achieve maximum power from your engine or for re-calibration of modified engines.The module gives the user a conveniente way to set A/F ratio for rich, lean or stechiometric operation over the entire RPM and load range.IT provides a means to achieve a best fit straight line of approximation to the desired Air/fel calibration curve.It gives the user the ability to make these adjustments without  riprogramming the ECU.Furthermore, these adjustments can be made by the driver on-the-fly to optimize the Air/fuel Ratio for the current driving situation.

Special consideration has gone into the ARC1-003 to make sure that the car operates like stock in most modes of operation.The benefit of stock operation are stock drivability,cold start,fuel economy and emissions.The most important benefit is that the ECU will not adapt to the changes made by the high knob.The ARC1-003 is designed to only alter the fuel curve at high engine loads where fuel adaptation does not occur.Therefore, the changes made will be permanent and will not result in a check engine light.The ARC1-003 does not directly affect the ignition timing curve. Most performance chips make more power by advancing the ignition timing.However, this is dangerous because on a hot day climbing a hill,you could wind up with too much advance and cause detonation in the motor.

Very important and usefull also on those engines with ECU modification but with other subsequent engine modifications.Normally you should modify the ECU again according to the added engine modifications made.By using the ARC1-003 you can change the Air/fuel ratio and adjust the fuel mixture by yourself at all times making the engine operating the best possible way in order to have the maximum increase of power with less fuel consuption and the lowest possible exhaust emmissions.

 
 

Air/fuel Ratio Calibrator  ARC1-003


Description:

The ARC1-003 Air/fuel Ratio Calibrator provides precise adjustment of air/fuel (A/F) ratio over the upper load range of an internal combustion engine. It is designed specifically for naturally aspirated engines with mild performance enhancements. The ARC1-003 follows the stock fuel curve over the light load range which minimizes adaptation on modern closed loop engine management systems. At higher loads, the fuel curve can be made more rich or lean to optimize engine performance. 

The LOW control of the ARC1-003 sets the threshold at which alteration of the fuel curve begins. The HIGH control sets the degree to which the fuel mixture is made more rich or lean. A provision on the ARC1-003 allows the modification to the fuel curve to be dependant on an external control input such as MAP or TPS. 

The ARC1 is typically used in conjunction with a precision air/fuel ratio meter such as the Split Second ARM1. The air/fuel ratio meter provides the required information needed to properly set the ARC1 front panel controls. 

The ARC1-003 is part of the ARC1 family. Several versions are available which are optimized for different applications. The standard ARC1 provides gain and offset calibration and is well suited for general purpose engine calibration. The ARC1-002 is tailored for engines that have been converted to forced induction. It provides compensation for larger injectors and adjustable enrichment in the boost region.

Features: 

Low control sets modification threshold
High control sets degree of rich or lean operation in high load range
Optional external control input
+5V regulated output available for MAP sensor reference voltage
Transient surge and battery reversal protection Wire Assignments:


LABEL CONNECT TO WIRE COLOR
BATT+ Battery positive (+12V) Red
BATT- Battery negative (chassis ground) Black
SIGI+ MAF/MAP sensor signal output Green
VC Green wire (optional connection to TPS) Yellow
SIGO ECU signal input (MAF or MAP input) Violet








Front Panel Adjustments:


LOW

The LOW control sets the point at which change to the fuel curve begins to occur. The threshold is based on the voltage on the yellow wire. The threshold point can be varied from 1V to 3V. If the yellow and green wires are tied together, the threshold is based on the input voltage.





HIGH

The HIGH control adjusts the degree to which the stock fuel curve is made more rich or lean above the threshold point. The amount of change to the fuel mixture is a function of the HIGH setting and how far above the threshold VC (the control voltage on the yellow wire) is.




Adjustment Procedure:

Begin with the low and high controls set to the zero position. At these settings, the output voltage matches the input. Use a precision air/fuel ratio meter  to monitor the operating fuel mixture. 

Ask for the price of  our Digital Air/Fuel meter.Very precise and clear, it allows you to monitor the engine fuel mixture in all situations.

For the best engine performance and to save your engine from  damages due a too  lean mixture.Applicable on normally aspirated engines and on turbo engines.Especially on Turbo modyfied engines our Digital Air/Fuel Indicator  is extremely  important to avoid engine breakages which might cost high amount of money to repair.Very easy to connect - instructions included.



Adjust the HIGH knob to the plus side to make the top end fuel mixture more rich. Adjust to the minus side to lean out the top end fuel mixture. The amount of change is a function of both the HIGH setting and how far above the threshold VC (the control voltage) is. For a similar amount of top end enrichment, if the threshold is increased, the HIGH setting must also be increased.

The LOW knob can be adjusted in order to change the threshold where change to the fuel mixture begins to occur. If the threshold is moved down, there is a risk of changes being picked up by the ECU and activating adaptation. Adaptation works to reduce the effect of fuel mixture changes made with the ARC1-003. If changes made through the ARC1-003 are negated by the ECU over time, the LOW setting needs to be increased so that the area of the fuel curve that is altered is above the primary adaptation area.
