E4E-B INSTALLATION GUIDE

• Start the car and observe that it runs smoothly.
• Observe that the green LED indication flickers.
• Turn the potentiometer from one end to the other and observe that the engine tune
• changes. This indicates that you are adding fuel or not.
• If you are in doubt of the exact fuel/E85 mixture in your tank: put the potentiometer midway.
• This is not a science project. A proximate position is sufficient, because your engine (ECU) will adjust the fuel amount to the exact required level.
• Drive the car normal.
• If you are towing or racing (Speeds above 120Km/H) then don’t read the following.

While driving (light load, cruising) with E85 you can adjust the mixture down until the car ‘struggles’ and then adjust up a little. This saves you up to 20% fuel.

Note: You are exploiting the other property of Ethanol: Its very high Octane rating. The engine will run a little warmer, which easily absorbed by your radiator at light loads.

After a while you will know how your engine reacts to different settings and you will find a mixture, which serves you well until you fill up, and have an ‘unspecified’ mixture in the tank.
