This is a not a kit but a essential parts package for a universal bi-fuel LPG injection system.  Assembling the parts contained in this package will NOT result in an EPA-certified fuel system.

Technocarb ESIP 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 ESIP complies with international emission standards.

Technocarb ESIP 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 ESIP is also compatible with standard turbo charged engines; however, vehicles with high level supercharging may experience problems running with LPG.  Please check with Technocarb in these cases.  Please indicate vehicle make, model, and year, as some makes will require a special ECU configuration.

Technocarb ESIP sequential injection ECU controller may not work properly with engines having a duty-cycle (RENIX type) injector controller with 3 ohms or less GASOLINE injector coil resistance.

Set-Up & Operation

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.

Because injection systems require 1 bar (~14.5 psig) of vapour pressure to operate, the lowest temperature that this system will run is about -24°C (-12°F).  When the tank pressure drops below 1 bar due to an empty tank or low temperature, the system will automatically switch back to gasoline operation.

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 propane 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.
