Main components of the VERSUS-GAS Under hood engine kits

  • The ECU VERSUS type “V” Controller
  • The VR-L “Standard” and the VR-L “Super“reducers for liquid fuel to vapor transformation.
  • Sequential Gas Injectors FH02



  • Processor: DSP with efficiency up to 70MIPSV-Type-Image
  • Housing: Aluminum
  • Dimensions: 138×133,5×38 mm
  • Connector: 2×24 PIN
  • Safety: original Leak Detection System “LDS”
  • Calibration: Self-Calibration System “SCS” supporting automatic correction adjustments
  • OBD Communication available
  • Integrated short circuit protection system
  • The self-diagnosis and troubleshooting system
  • Supports engines up to 8 cylinders depending on the type of controller


 VR-L “Standard” reducer:

  • Type of GAS: LPGVR-L-Image
  • Body: Aluminum die cast
  • Gas Outlet Pressure: 1 bar
  • Maximum Power: up to 200 horsepower or 2 in series for over 300 HP
  • Working Temperature Range (°F): -22 /+248
  • Gas Outlet External Diameter: 12 mm
  • Gas Inlet: 6 mm
  • Engine Cooling liquid Outlet/Inlet: 16 mm
  • Shut-off Valve: supplied
  • Solenoid Valve Nominal Voltage: +12V
  • Overall dimension: 135/190/130 mm
  • Body Diameter: 100 mm
  • Weight: 1,45 kg
  • Approvals: ECE67R01
The latest VR-L Standard reducer is designed according to the most recent knowledge. Due to that factor the most efficient temperature exchange values as well as optimal pressure performance were obtained. That was proved by testing it in extreme conditions. VR-L Standard reducer comes together with LPG Solenoid, so there is no need to install additional valve, which saves space in the engine compartment.


 VR-L “Super” reducer:

  • Type of GAS: LPGVR-L-Super-Image
  • Body: Aluminum die cast
  • Liquid Gas Heating System “LGHS”: supplied
  • Gas Outlet Pressure: 1.2 bar
  • Maximum Power: up to 300 HP or 2 in series up to 600 HP
  • Working Temperature Range in (°F): -22 /+248
  • Gas Outlet External Diameter: 14 mm
  • Gas Inlet: 8 mm
  • Engine Cooling liquid Outlet/Inlet: 16 mm
  • Shut-off Valve: integrated
  • Solenoid Valve Nominal Voltage: 12V
  • Overall dimension: 135/190/130 mm
  • Body Diameter: 100 mm
  • Weight: 1,9 kg
  • Approvals: ECE67R01
VR-L Super reducer is designed for the most sophisticated engines with high efficiency out-put. This reducer can be installed in engines up to 300 Horsepower. It is supplied with advanced Liquid Phase Heating System. Due to that it ensures stable pressure in spite of outside temperature. It also has built in Coil Group Valve, so there is no need to install another valve separately.


Injectors FH02:

  • Body: aluminumFH02-1
  • Fuel: LPG
  • Voltage: 12V
  • Working Pressure: 0.5 -2.5 bar
  • Maximum working pressure: 4.5 bar
  • Opening/closing time: 3.0 msec/2.5 msec
  • Resistance of the coil: 3 Ohm ±4%, other upon request
  • Temperature Range (°F): -22 /+248
  • GAS Inlet (external): 12 mm, other upon requestFH02-2
  • Standard Valve seat diameter: 4 mm
  • Calibration nozzle sizes available: 1.5 – 3.5 mm in (0.25 mm steps)
  • Body composition available: 2-cyl, 3-cyl, 4-cyl
  • Normally: closed
  • Approvals: ECE 67R01, ECE110R00
The most popular solution for most of engines with easy access to the inlet manifold.

Types available:

1. FH02 4-cyl – dedicated to 4-cyl & 8-cyl engines where there is room for no more than the 8 inches of hose length for connection to nozzles.
2. FH02 3-cyl – dedicated to 6-cyl engines, with 3 (three) injection channels present
3. FH02 2-cyl – dedicated to 4-cyl boxer engines or 8-cyl engines where the 8 inch maximum distance of injector hose cannot be achieved with the 4 injector rail.

!   Please note that for your first order  you will need :

1. USB / VERSUS interface cable USB. Together with the interface cable there is
a CD with all installation information – manuals, software, diagrams  etc.)

2. Also Recommended: An installation starter kit for 4, 6, or 8 cylinders

(this includes a set of some typical installation accessories that can be essential during your first installation)
