 Electronic fuel injection enhancer digital control panel increase fuel savings in trucks 

In the early days of HHO generator technology, many trucks were unable to have fuel savings higher than 22,5% due to the strict parameters of their computer management systems. These trucks have electronic fuel injection with advanced ECUs (Engine Control Units with Euro modules IV and V) and some would simply not allow fuel economy to be improved beyond a certain programmed value.

As HHO generator technology advances, more trucks are now able to benefit despite these ECU limitations. The new electronic fuel injection enhancer EFIE-DCP is one of the newest products to address these problems and solve the limitations of many modern vehicle ECUs making possible now to have high fuel savings in the most modern trucks and cars.

What is a EFIE-DCP?

The EFIE-DCP is the most advanced electronic fuel injection enhancer (EFIE) in the market. It uses OBD scan tools allowing the control in real-time of the MAF/MAP sensor (airflow sensor) and two oxygen sensors (lambda sensors). With the digital control panel you will be able to check the engine performance by looking at several parameters available:

  • Coolant temperature in degree Celsius;
  • Vehicle speed in km/h;
  • Engine speed in rpm;
  • MAF rate in g/s;
  • Oxygen sensor in voltage;
  • Fuel trim in %;
  • Fuel consumption gph in l/100 km.

Any regulations made in the EFIE-DCP can be instantly monitored by looking at the panel and the effect on fuel consumption evaluated. You will no longer need to be making regulations “blindfold” like in others EFIEs available in the market. This means higher fuel savings in your car or truck.

Additionally normal EFIEs just allow one possible regulation point causing some problems because when we are driving we are constantly changing the speed of the vehicle and engine performance. This single regulation position will never match perfectly the performance of your car causing problems because sometimes the engine light to be turned ON or resulting in poor fuel saving results.

Possible sensors configurations

According to your installation configuration you need to activate the sensors in order to be able to regulate and change the electronic injection. You may work with the following options:

  • 3 sensors enhanced – 1 x MAF/MAP + 2 x Lambda sensors;
  • 2 sensors enhanced – 1 x MAF/MAP + 1 x Lambda sensors;
  • 2 sensors enhanced – 2 x Lambda sensors;
  • 1 sensor enhanced – 1 x MAF/MAP;
  • 1 sensor enhanced – 1 x Lambda sensor.

What is included in the package?

The EFIE digital control panel package includes the following items:

  • 1 Main connection box
  • 1 Digital control panel
  • 1 Connecting cable
  • 4 Red scotchlok terminals.

What protocols can be used?

Support for all legislated OBD II protocols:

  • ISO 15765-4 (CAN)
  • ISO 14230-4 (Keyword protocol 2000)
  • ISO 9141-2 (Asian, European, Chrysler vehicles)
  • SAE J1850 VPW (GM vehicles)
  • SAE J1850 PWM (Ford vehicles)

Support for non-legislated OBD I protocols

  • ISO 15765
  • ISO 11898 (raw CAN)

Support for SAE J1939 OBD protocol

Software updates

You will have the possibility to update the software on the EFIE-DCP according to the software releases of our team. You just need to download the last update and transfer it to a SD memory card. You just need to insert it in the embedded lateral SD card slot and reboot the EFIE-DCP. Simple and fast you will have from time to time new features available!

Together with the correct selection of the HHO Kit, we advise the installation of the MAF/MAP enhancer control box in all modern diesel common rail trucks, Euro IV and Euro V.
