Introduction 

The Alternative Performance Engineering Multi-Gauge is the most advanced 
Ethanol Content sensor available in the market today.  The Multi-Gauge also 
has two generic 5V sensor inputs that can be used for additional sensors like 
a wideband or map sensor.  All of this data can be monitored and data-logged 
wirelessly via Bluetooth Low Energy on our Android or iOS application. 

The Multi-Gauge also provides a raw ethanol sensor output with built in 10K 
pullup resistor to 5V so you can use it on a vehicle that already has a flex 
sensor.

How you enter the values in the 0V and 5V boxes will be how the numbers are 
displayed on the Gauges.  For example, of you put 7.35 and 29.4, the gauge 
will display 2 decimal points.  If however you put 7.4 and 29.4 the gauge will 
only display one decimal point, and if you put 7 and 29 then the gauge will not 
display a decimal point.  You can also enter 0% and 100% if you want it display 
the number as a percentage.
