Getting Started
Vehicle Health
It is important that your vehicle is in proper working order and has been
well maintained. The fuel pump and the emissions system are important
for proper vehicle operation. The fuel pump pressure and flow should be
within the standards set by the vehicle manufacturer. Make sure that all
other vehicle sensors are in proper working condition. After confirming
the compliance of the data above, you may proceed with the installation.
Change the oil, oil filter and fuel filter since ethanol will act as a cleaner.
It is recommended to change your oil between 500 and 1000 miles after
the module installation and E85 usage. Change the fuel filter around 1000
miles after E85 usage. From then on, the changes should be made at
manufacturers recommended intervals.
•
APE recommends that your Muliti-Gauge is fitted by an appropriately qualified
technician.
•
Consult your local tuning specialist before configuring your boost controller settings,
setting your boost beyond your engines capability can result in severe engine damage
or failure
•
APE recommends that the engines Air/Fuel ratio is checked once the desired boost
pressure is set. Any increase in boost pressure can cause the engine to run lean
resulting in severe engine damage or failure
•
APE recommends that the Flex Boost is not used in conjunction with any type of “Draw
Through” induction System.
•
APE recommends that boost pressure is set using a Dynamometer and not on public
roads.
•
The Flex Boost may not be able to completely compensate for a drop in boost pressure
at high RPM due to the turbocharger operating beyond its maximum efficiency range
i.e. incorrect turbocharger sizing or excessive exhaust backpressure.
•
The Flex Boost cannot compensate for increases in boost pressure at high RPM due to
inadequate waste gate flow capacity; the turbo system must maintain a steady base
boost curve before you start using a boost controller.
•
The Flex Boost cannot be used with external waste gates that are in a poor, worn or
non-serviceable condition.
•
For best results your turbocharger should be correctly sized for your application.
•
Erratic operation of electronic parts can be caused by Electro Magnetic Interference
(EMI). EMI can be generated by aftermarket ignition systems such as CDI which, if wired
incorrectly, generate large amounts of EMI through the vehicles electrical system. This
can cause items such as ECU’s and boost controllers to be effected. Please follow
ignition system installation instructions VERY carefully to avoid EMI affecting the Flex
Boost. Sometimes, using resistor type spark plugs can reduce this problem.
•
The Flex Boost is not waterproof and must be mounted inside the cabin. The unit has
an operating temperature range of -5 °C to 70 °C.

Fuel Calculator Screen
The fuel calculator can show you how to mix Ethanol with Gasoline to
achieve a desired Ethanol mixture, for example E65. You can use the
datalogging screen to help determine if you need to lower your Ethanol
mixture.
As a reference, for every 10 percent increase in Ethanol will increase the
pulse width extension by 4%. So, at E50 the module is adding 16% more
fuel, and at E60 the module is adding 20% more fuel.
