3. FAQ
Cold weather use
eFlexFuel® has been designed, tested, and manufactured in one of the coldest countries on earth, Finland. Thus, a great deal of
emphasis has been put into ensuring that the device and the vehicle will also work in cold conditions. Vehicles equipped with
eFlexFuel® will start even in the coldest temperatures. However, in extreme conditions a couple of starts might be required with pure
E85 fuel.
E85 does not evaporate as easily as gasoline. Therefore, in cold temperatures (less than 5°C) we recommend taking the following steps:
o
Fill up with some gasoline (10% or more) to lower the ethanol content.
o
Make sure that the engine is well maintained and, in particular, the ignition components and spark plugs are in normal
working condition.
o
Avoid long cranking. We recommend short start-ups (2-3 seconds) and adequate pauses in between attempts (5-8
seconds). This helps ethanol to evaporate in the cylinders before attempting to start the engine again.
o
eFlexMoto Plus and eFlexMoro Pro come with an adjustable cold start feature that is accessible from the eFlexApp
eFlexTuner. This will allow you to configure the cold start specifically for your vehicle, if needed.
The fuel consumption reading does not match actual consumption
In most vehicles the fuel consumption readout is calculated based on injection pulse width. The real fuel consumption may differ from
the original fuel consumption using ethanol E85.
eFlexApp® fault codes
Fault codes may appear if there are pre-existing electrical problems that influence the operation of the eFlexFuel® control unit.
Ethanol sensor not connected
o
Check that the ethanol sensor connector is properly attached, and the wire is not damaged.
o
Check that the pins on the connectors are not oxidized and/or damaged.
o
Check that the wiring harness routing is not close to high voltage components.
Low ethanol content
o
The ethanol sensor has detected a low ethanol content. The warning limit is 2 percent (%). Under normal circumstances,
gasoline contains at least 5 percent (%) ethanol.
o
If the ethanol content reading is 0 percent (%), make sure that the ethanol sensor is connected to the fuel line and not to
e.g., a breather hose.
o
A low ethanol content reading can indicate a low fuel pressure. There is air in the fuel line, and varying ethanol content
readings are displayed. The fuel pump may be worn out, or the fuel filter can be clogged.
Fuel is contaminated
o
The ethanol sensor has detected contaminated fuel. If the sensor cannot detect the right ethanol content, the value is set
to 40 percent (%) as a safety precaution. NOTICE: avoid driving with this condition or refuel the vehicle with a 50/50
percent (%) mixture of ethanol and gasoline.
