The Full Flex GOLD installation is simple and is made using connectors*, without cutting wires and without interfering in the vehicle originality.

* Check the vehicle compatibility (application table)

Full Flex GOLD is installed on the line of the injection nozzles and a wire connected to the negative of the battery. (see the Connection Diagram for better installation).

To put the ethanol/gasoline electronic system in operation immediately after its installation, it is necessary to use a mixture of 50% of ethanol and 50% of gasoline so that the new system can calculate new operation parameters, both in terms of injection time and advance of ignition.

FULL FLEX GOLD Manual

General Inspection of the vehicle condition, such as:

Spark plugs and spark plug cables Change of engine oil
Fuel and oil filters Cooling liquid
Cleaning of the injection nozzles Lambda Probe Sensor
Fuel pump Or any other defect
MAP Sensor    

 

 

 

 

The items above should be inspected and changed if necessary, considering that the vehicle has run with gasoline for a long time. This fuel causes a great internal carbonization in the engine, like oil sludge and a high degree of rust in the cooling liquid.

When you start using ethanol, that is a cooler and cleaner fuel, the carbonization left by the gasoline in the combustion chamber internal valves starts to get loose and may cause a premature wear of the valve control, of the catalyst and even burning of the fuel pump.

The correct operation of the system requires that some vehicle sensors, like the MAP sensor and the Lambda Probe sensor are in perfect condition and that the injection nozzles are clean. In case of deficiency in these sensors, the vehicle module will receive erroneous information that will be relayed to the bi-fuel manager and consequently generate wrong calculations for the vehicle, thus causing an economy failure.
