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.  It is recommended that you note 
the Serial Number and Passkey here in your manual for future reference 
in case it is not readable after the Flex Boost Module has been mounted 
in your car.

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.   
 

 

 

Range 1 is setup 
here to turn off 
the solenoid when 
the engine is off 

0% means the 
duty cycle is set by 
the basic settings 
above, you can 
increase or 
decrease each 
RPM range as 
much as you like. 

Changing the RPM 
range in one range 
will affect the 
others.
