Thank you for purchasing an AEM Engine Management System.  
 
The AEM Engine Management System (EMS) is the result of extensive development on a 
wide variety of cars. Each system is engineered for the particular application. The AEM 
EMS differs from all others in several ways. The EMS is a stand alone system, which 
completely replaces the factory ECU and features unique Plug and Play Technology, 
which means that each system is configured especially for your make and model of car...

Engine Wiring Harnesses, ‘swapped’ engine installations
 
Many Nissan wiring harnesses have been found to contain significant differences between 
model years and/or trim levels. Likely differences include: Crank signal, Cam signal, 
Ignition switch wiring (the Ignition switch input controls the Main Relay output), injector and 
coil destinations. Official documentation for these vehicles was not offered in...

injectors with the stock ECU. With the 30-6610 installed, users can elect to remove and 
bypass the OEM resistor pack for more precise control of low-impedance injectors.  
 
Please note that the injector response time will be different with and without the factory 
injector resistor pack. If the OEM resistor pack has been removed and bypassed, please 
use the correct battery offset wizard for your injectors. Most battery offset wizards will 
specify  if they are intended for use without a...

3)  Install the AEM Engine Management System 
a) Plug the factory wiring harness into the AEM EMS and position it so the wires are 
not pulled tight or stressed in any manner. Secure the EMS with the provided 
Velcro fasteners. 
b) Plug the comms cable into the EMS and into your PC. 
c) Turn the ignition on, but do not attempt to start the engine.  
d) At the time these instructions were written, new EMS units do not require USB 
drivers to be installed on the PC. 
e) With the AEMTuner...

c) Note: This calibration needs to be properly tuned before driving the vehicle. It is

NEVER TUNE THE VEHICLE WHILE DRIVING
 
 
 
5) Troubleshooting an engine that will not start 
a) Double-check all the basics first… engines need air,...

If the Engine Load changes when the throttle is pressed this usually indicates that 
there is a problem with the MAP sensor wiring or software calibration (when the 
EMS detects that the MAP Volts are above or below the min/max limits it will run in 
a failsafe mode using the TPS-to-Load table to generate an artificial Engine Load 
signal using the Throttle input). This may allow the engine to sputter or start but not 
continue running properly....

30-1610 (Series 1) vs 30-6610 (Series 2) EMS differences:
 
The EMS functions assigned to certain pins have been changed and no longer match the 
30-1610 EMS. Unless otherwise noted, the following pins and functions will need to be 
manually reconfigured after using AEMTuner to convert a V1.19 30-1610, Series 1 EMS 
calibration for use with the 30-6610 Series 2 hardware.
