External MAP 0-5V Installation 

Operation: 

The 0 

– 5 Volt external MAP mode is designed for vehicles running high boost, beyond that of 

the Internal and HD models, or for users who already have a sensor or output of their MAP with 
a range of 0 

– 5 Volts.  See Table 1 for compatible AEM MAP sensors. 

 

Dip Switch Settings: 

ON 

– ON – ON

 

 

Setup, Connection:  

To setup your system for external MAP you must first find the correct source to connect to. In 
order to locate the correct signal the use of a volt meter will be required. Once you have located 
your MAP sensor you can begin to check the wires for the 

“signal” wire. The signal wire should 

remain at or near 0 Volts when the car is turned off or is not running. Once the vehicle is started 
it should continue to remain at or near 0, however it may begin oscillate up and down slightly. To 
determine if you do in fact have the correct wire you can try and rev the engine while monitoring 
the voltage. You should observe the signal rising and falling with engine speed.  Please note 
that you may need to rev the engine high enough to put it into boost. Once you have found the 
correct signal wire you may tap onto it (if it is used by other devices), or connect it directly to the 
Water Methanol controller (Pin #11 

– Blue). 

 

Testing:

 

To test your setup it is recommended you finish the installation, but before installing the nozzle 
you run the engine and ensure the system is operating as expected. That is when the engine is 
running and the MAP sensor is outputting in a range set by the controller you will get flow. You 
want to ensure you are not getting flow when the engine is turned off or is not expected. This 
could be due to improper wiring or the incorrect mode selected.
