Universal LPG bi-fuel multiport vapour injection underhood kit for 6-cylinder gasoline engines.
Digitally Controlled, Sequential Vapor Injection Conversion Kit. The closed loop LPG digital controller is an advanced computerized device factory that can be pre-programmed for each specific application.
Digital signals gathered from the engine operation, such as the exhaust gas oxygen content, RPM, TPS, Fuel Pressure, Vacuum Pressure, Fuel Temperature and Gasoline Injector Actuation Pulses. In many late model applications the SVIS can connect directly to the OBDII system. This digital system controls and adjusts the LPG ratio by precisely pulsing measured vapor fuel (measured in milliseconds) to each separate cylinder injector.
Vapor injectors are installed directly into the intake manifold as close as possible to the OEM gasoline injectors virtually eliminating “lag” found in other systems.
The digital controller keeps the onboard gasoline computer active in its monitoring, diagnostics and controlling functions even while the vehicle operates on the alternative fuel.
Technocarb LPG digital controllers allow for full on road diagnostics, calibration and configuration utilizing user-friendly Windows based platform software which will run on a laptop or desktop computer. Many vehicle applications allow for direct connection to the OBDII diagnostic port (CAN Bus) allow unequaled performance and enabling fuel trim data to be read on your laptop (no need to use a separate OBDII scan tool!)
The LPG digital controller uses sophisticated software developed to compute the most efficient alternate fuel injection ratio to achieve low fuel consumption and low emissions, yet providing the best possible drivability and power.
The Technocarb LPG digital controller does not interfere in any way with the OEM onboard controller, meeting compliance regulations for all current international alternate fuel regulations.
State of the art injectors SPECIFICALLY designed for vapor fuels (unlike re-worked gasoline injectors) give superior performance and durability while also being more forgiving of contaminated fuel.
All components meet US/Canadian and International safety standards.
All LPG regulators are specifically designed and tested to ensure excellent performance, service life and durability on high demand North American engines as well as all import applications.
Many SVIS systems are now supplied with fuel injector “interface harnesses” these harnesses allow the installer to just “plug & play” the injector wiring portion of an installation, cutting hours of work (and the potential for wiring errors) greatly.
This is a complete universal, underhood conversion kit kit for a bi-fuel LPG injection system. This kit does not carry ANY EPA or CARB certifications.
Technocarb SVIS Sequential LPG Injection Systems are designed for vehicles equipped with electronic combustion emission control and diagnostics systems (OBDII or EOBD), with a catalytic converter and oxygen sensors. When properly installed and calibrated, Technocarb's SVIS complies with international emission standards.
Technocarb SVIS systems can be installed on engines with multi-point fuel injection, sequential injection, semi-sequential or single point injection. This system is also designed for multiple displacement engines.
Technocarb SVIS is also compatible with standard turbo charged engines; however, vehicles with high level supercharging may experience problems running with LPG. Please check with us in these cases. Please indicate vehicle make, model, and year, as some makes will require a special ECU configuration.

- "FACTORY MATCHED COMPONENTS BOX PACKAGING" Concept insures that the system is installed to the highest standards
Technocarb conversions are designed to operate as seamlessly as possible. Starting your vehicle on LPG is as easy as starting your vehicle on gasoline. Bi-fuel conversions always start on gasoline and then automatically switch to LPG when the engine reaches a software-configurable set point (normally 60°C / 140°F). This is to ensure that the gasoline system is always operating correctly, and no problems occur when the LPG storage is depleted. This also prevents the gasoline from becoming stale.
Because injection systems require 1 bar (~14.5 psig) of vapour pressure to operate, LPG operation is affected by ambient temperature because LPG is a liquefied gas. The boiling point of propane (typically the main component of LPG) is -26°C / -15°F at 1 bar. When the fuel is depleted and tank pressure drops as a result, the system switches back to gasoline operation automatically.
This system operates by duplicating the operation of the existing gasoline EFI system. A sequential gasoline injection system results in a corresponding sequential LPG injection system. A batch gasoline port-injection system results in a corresponding batch LPG port-injection system. A single-point or TBI gasoline system results in a batch LPG port-injection system.
A fuel selector switch is installed on the dashboard of bi-fuel vehicles. A yellow LED indicator lamp indicates LPG operation while a red LED indicator lamp shows gasoline operation. Depressing the fuel selector button switches the fuel mode from gasoline to LPG and vice-versa.
In addition to the normal mode of operation, this system may also be configured through software to operate in mono-fuel mode so that the gasoline system is never used.
Most vehicles utilize the gasoline fuel level indicator when operating on LPG. Some vehicles only have a sight gauge on the LPG tank and some have an indicator integrated into the fuel selector switch.
Drive your vehicle on natural gas as you normally would on gasoline. In the event that your LPG storage is depleted during normal operation, the system will automatically switch you back to gasoline.
