Dealing with electronics

Adding Hydrogen changes the combustion properties of the existing fuel, increasing power and fuel economy. The Hydrogen – fuel mixture burns more efficiently with less pollution and more Oxygen content in the exhaust.

Fuel injected vehicles are equipped with multiple sensors. The ECU monitors all the sensors and it is programmed to expect a certain “normal” behavior.

When the sensors detect the altered combustion and the excess of oxygen in the exhaust, the ECU responds to this unexpected condition by adding more fuel and negating the improvement in fuel economy. If sensors are not adjusted properly, it is common to have more power and torque, but no fuel savings.

Achieving better fuel economy is a two step process:

1. Improve combustion efficiency by adding HHO. This results in increased engine torque and power.

2. Use ProTuner to adjust the signals of the sensors and to reduce the quantity of unnecessary fuel being consumed, converting surplus power into economy gains.

Carburetor engines are not equipped with sensors that direct the computer of the vehicle (ECU). In this case, installation is most simple as it only requires a hydrogen generator and a CCPWM to control the amount of HHO and the temperature of the operation

Electronic Fuel Injection Enhancer – EFIE

HHO allows the engine to run with leaner (less gasoline) air-fuel ratios while maintaining the same performance. The computer of the car (ECU) monitors the Oxygen sensors in order to decide how much fuel to use at any given time.

EFIE is an electronic device that makes adjustments to the signals coming from the oxygen sensors, so that the computer does not interfere with the operation of HHO

There are three types of EFIEs:

  • Front narrowband EFIE controls front narrowband oxygen sensors
  • Front wideband EFIE controls front wideband oxygen sensors
  • Rear EFIE controls rear oxygen sensors

ProTuner contains all three EFIEs as part of its tuning system.

Why do I need a ProTuner? Why is an EFIE not enough?

Adding an EFIE electronic controller will slightly improve the fuel economy. At the same time, it also creates a conflict among the sensors that guide the computer. When you modify only one sensor, this condition is no longer consistent with the ECU’s expectations.

Although this is acceptable and normal, the economy results will depend on just how much of this conflict a car can tolerate.

The ProTuner adjusts all the sensors of the fuelling system, minimizes the conflict and maintains harmony within the system.

ProTuner is an all-inclusive automotive controller for any engine equipped with Oxygen sensors, IAT, MAP, MAF sensors. This controller also features an integrated CCPWM.

How ProTuner adjusts sensors to improve fuel economy:

  • EFIE – Oxygen sensors controller makes the ECU think that there is too much fuel in the engine. The ECU responds by reducing the amount of fuel sent to the system.
  • MAP sensor controller makes the ECU think the car is going down a hill. All vehicles use less fuel while going downhill.
  • IAT controller makes the ECU think that the air entering the engine is warmer than it really is. This results in beneficial adjustment in ignition timing and also a reduction of fuel consumed.

Typical fuel saving results

Individual results will vary GREATLY, depending on the quality of install, amount of HHO injected, type of vehicle and the type and number of sensors you manipulate.

HHO only, no sensor adjustments: 10-25%

HHO + ProTuner: 30-60%

What is a Pulse Width Modulator?

HHO systems are based on electrolysis and produce substantial heat. If the heat does not get controlled or does not dissipate, inevitably it will build up and boil the water in the system.

Pulse Width Modulator (PWM) is a device that controls the current, the amount of HHO produced and the temperature of the operation.

Why use Constant Current PWM (CCPWM)?

The problem with regular PWMs is that they allow the HHO generators to increase the flow rate and draw more current as they get warmer. This condition is known as ‘Thermal Runaway’ and it leads to boiling the water in the system.

For example, if you set the generator to 10 amps; it can increase up to 15 amps when hot. This is not desirable as any HHO system requires a constant HHO flow; if not, it will keep blowing fuses.

CCPWMs maintain original settings regardless of the changes in the operational conditions.

Advantages of the CCPWM

Remote low water indicator. Flashing light in the cabin alerts you when the HHO generator requires servicing

Advanced safety features. CCPWM automatically turns itself on/off ONLY when the engine is running.

Built-in AMP meter. No need for an external AMP meter

LCD display. Allows the user to monitor the status of the HHO system and measured amperage.

Very high current capacity: 60 amps

Precision Output. Powerful microprocessor automatically controls an accurate constant current output with precise 0.5 Amp steps.

Direct battery connection. No relay required, no need to look for ignition switched power supply.

Easy to use. Simple two button interface (Up/Down) to adjust the amperage setting.

Excellent reliability. No fans or other moving parts to break down. Proven, field tested design. Professionally manufactured equipment.

Excellent installation instructions. Professionally written, easy to understand instructions.
