Analog Voltage Inputs (Assignable V# in the Analog Settings and ANA Vx in Pinout/Wiring Diagrams) are direct 0-5V inputs to the ECU.


They should be used with sensors that generate a voltage output (such as Throttle, MAP, MAF, Lambda etc). You would then assign the chosen channel to correct sensor "RAW", such as TPS RAW  in the Analog Settings. 


They are protected, high impedance inputs, which means they can be wired in parallel with stock ECUs if required and won't effect the stock ECUs reading.


Over-voltage (over 5v) should be avoided where possible as damage to the input can occur if excessive repeated over-voltage spikes occur.


You can see some examples of these sensors wired to the ME442 here.


Extra Temperature Inputs

Note you can also wire thermistor/resistive sensors to these voltage inputs, but you will need to fit a 2700 ohm pull-up resistor (such as these) to the input and the 5V REF supply, such as the diagram below:
