ECU
The Lima-ECU controls the LPG system by:
- Measuring the OEM signals, petrol-injectors, rpm, MAP, coolant, etc.
- Controlling the Lima LPG-solenoids
- Controlling the Lima LPG-injectors
- Shutting off the petrol-injectors
- Displaying fuel choice
- Communication with the diagnostics program
- Injector drivers based on “closed loop peak & hold current control”
- Constant monitoring of the injector diagnostics:
- Overload
- Driver temperature
- Short circuit
- No load
- Communication with the diagnostics program
- Diagnostics software compatible with Windows 98, 2000, XP and Vista
- CAN-controller (2.0b) enables communication with OEM CAN-bus
The reducer
This device converts liquid LPG to vaporized LPG using the coolant system of the engine. It also serves to reduce the tank pressure to working pressure.

| Min. input pressure | 2 bar (30 Psi). |
| Max. input pressure | 18 bar (260 Psi). |
| Working pressure | 0.6 Bar (9 Psi) to 1.6 bar (23 Psi) (adjustable). |
| Fuel | Liquefied Petroleum Gas (LPG). |
| Gas outlet | Rotating elbow connection, 16mm outside diameter |

| Operating temperature | From -40° C to 120°C (-40° F to 248° F). |
| Max. operating pressure | 4.5 bar (65 Psi) according to R67-01 (Opening of the pressure relief valve). |
| Remark | all pressures are absolute |
LPG Filter Unit
This device is filtering the fuel to prevent damage to the injectors. The filter unit is also equipped with a pressure/temperature sensor for the fuel.
| Type | Replaceable filter. |

| Gas inlet | 16 mm outside diameter, straight. |
| Gas outlet | 11 mm outside diameter, one or two connections. |
| Weight | 0, 11 kg. |
| Fuel | Liquefied Petroleum Gas (LPG) or Compressed Natural Gas CNG). |
| Max. operating pressure | 4.5 bar (65 Psi). |
LPG Injectors
Gaseous Fuel Injectors with 0.45 MPA max working pressure, electrical coil resistance of 2.5Ohm, AMP/Delphi superseal incorporated connector. The injectors are available in different versions with 2, 3 and 4 injectors, with gas INLET option for both sides of the rail.
