  • Page 5: Introduction

    The Alternative Performance Engineering Flex Boost is an advanced electrnoic boost controller, ethanol gauge and generic Bluetooth gauge all in one. Flex Boost combines all of the features of our Flex Boost product with the addition of a programmable boost controller. Boost can be configured based on Ethanol content or RPM and if you add a manifold pressure sensor you can configure an Over-Boost Fail safe.

    • The Flex Boost cannot be used with external waste gates that are in a poor, worn or non-serviceable condition. •...

  • Page 7: What's Included

    Check to make sure you have all of the necessary components in your kit: • Flex Boost Module • Wiring Harness • Flex Boost Solenoid and fittings • Flex Fuel Sensor (optional) • Quick Connect Fuel Fittings and hose clamps •...

  • Page 8: Module Passkey

    Module Passkey On the back of the Flex Boost Module there is a sticker that looks like this. This indicates the Serial Number (SN) and the Passkey (PK) that is used by the IOS or Android app to allow the user to alter any of the default configuration parameters of the device.

  • Page 9: Installation

    1) Install Flex Fuel Sensor anywhere in the fuel lines. A good place is at the fuel filter. Make sure the Flex Fuel Sensor connector on the Flex Boost wiring harness is able to reach the sensor. 2) You can use the supplied fuel line adapters to connect the Flex Fuel sensor to the fuel filter.

    Play Store. Open the app and connect to your device, you should see your serial number listed as something like “APE-FB-10001”. Select your device and hit “Connect” to get to the main dashboard of the app. The app may ask...

  • Page 15: Flex Boost Features

    Flex Boost Features Ethanol and Fuel Temperature Gauges The Main dashboard screen displays the Ethanol content and fuel temperature as read from the ethanol content sensor. It also has two mini gauges that are used to display the two 0V-5V inputs.

  • Page 16: Dc Gauges

    DC Gauges Selecting either Gauge 1 or 2 in the top corners will swap that gauge into the center and put the Ethanol Content in the corner. The scaling and visual appearance of the gauges can be configured in the settings tab. If you set the warning range in the settings tab and your gauge hits that range, the gauge will turn red.

  • Page 17: Landscape Mode

    Landscape mode If you are on the dashboard screen and rotate your phone counter- clockwise, then you the gauges will rotate to a landscape view. If you are on the dashboard screen and rotate your phone clockwise, then you will be taken to the data-logging screen.

  • Page 18: Data-Logging Screen

    Data-Logging Screen Rotating your device to the right will show the data logging screen. You can only get to the datat logging screen from the main dashboard, so if you are on the boost controller tab and want to see datalogging, you have to go back to the main dashboard tab and then rotate your phone clockwise.

  • Page 19: Boost Controller Screen

    Boost Controller Screen The Boost Controller screen shows you both of the DC gauge inputs and it shows you the current duty cycle being sent to the Flex Boost Solenoid. Current value read Current value read by Gauge 1 input.

  • Page 20: Boost Profile Editing

    Boost Profile Editing You can have up to four profiles, and they are completely customizable. See description of all of the settings below. The Flex Boost allows the user to set up the boost controller duty cycle for two different ethanol settings.

  • Page 21: Rpm Based Boost Control

    RPM Based Boost Control You can raise or lower the Boost Controller duty cycle across four separate configurable RPM bands. You must have the Tach input enabled and configured correctly for this to work. We recommend setting a RPM range below idle, and then setting it to -100% in order to keep the Flex Boost solenoid from clicking when the engine is not running.

  • Page 22: Over-Boost Safety

    Over-Boost Safety The Flex Boost has the abilityh to configure one of the DC gauge inputs for Over-Boost Safety. You must first configure your Gauge settings and then you can select that gauge in the Over-Boost Safety drop down in the settings tab.

  • Page 23: Fuel Calculator Screen

    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.

    This determines which value is output on the Pass Key not used for White wire. E85 (E0 = 0V, E85=5V), Flex Boost Gauge 1 or Gauge 2 Display Name is what Can turn off Gauge is shown when Gauge Display on dashboard is in the Center.

  • Page 25: Dc Voltage Output

    5V = E85 content. Note: The DC Out signal has a weak drive strength, if feeding into an ECU with a pullup resistor, the Flex Boost may not be able to drive this signal all the way to ground. In this event, calibrate your low voltage point accordingly in your ECU.

  • Page 26: Gauge Customization

    Gauge Customization You can change the end points in the color bar to change the upper and lower limits shown on the gauge. This can be useful if you have a sensor that displays a much higher range than what is needed for your application.
