Fuel Vaporizers – delivery times, EFIEs

The 'kits' have the completed components supplied, with each installation consisting of 1 or two main components along with control valves, T connectors and other fittings: enough for the average installation. Only fuel hoses are not supplied because of their bulk - these can be obtained at any local auto supply store, or are available from us as a separate item. There is nothing to build - only install. If additional components are required, we will swiftly supply them, or they can be easily obtained locally from auto supply stores.

Devices can be removed, or circumvented from operation in a vehicle in case of malfunction in 5 - 15 minutes, either with no tools or at most a pair of pliers and a screwdriver. You can also just shut off the device by turning a valve by hand in a few seconds.

In vehicles which use electronic fuel injection, the increased efficiency creates an increase in oxygen output in the exhaust - basically, less pollution. This affects lambda sensors, which will read the increased oxygen output as meaning the fuel/air mixture is too lean, and therefore pump more fuel through, negating somewhat the economy benefits of the vaporizer. If nothing is done to compensate for this, fuel economy benefits can be limited to about 10-15% - in some cases. However, a simple electronic circuit – called an EFIE (Electronic Fuel Injection Enhancer) has been developed – originally by George Wiseman and now by many other suppliers - which can be used to compensate the reading coming from the oxygen sensor before it is picked up by the fuel injection computer. In about half the installations, it will make no difference to the overall savings whether an EFIE is installed or not. A simple version can be built by any user with a small amount of experience in electronics. More complicated EFIE circuits – I can't claim they are any better, but they are more sophisticated – can be found at sites like http://www.hydrogengarage.com .

Another alternative to the EFIE is the lambda or oxygen sensor simulator - this allows the use of several devices without further adjustment. These can be found at http://www.magnumtuning.com . These simulate the lamdbda sensor, without trying to calibrate the signals coming from it - an advantage if more than one fuel saving device is used.

To ascertain whether an EFIE or simulator is necessary, contact us. Generally, for vehicles manufactured after 1990, they will be necessary.

Delivery times are around 4 weeks for devices (because they are modified to the vehicle they are going to be installed in) and 1-2 weeks on manuals.

Please note that all deliveries for vaporizers are done in 2 parcels that are sent simultaneously - this is cut down on postage costs from the UK, as a preferential rate is given for parcels that are less than 2 kgs.
