| JSC Speed Project Integra GSR: AEM Engine Management System |

Next to the supercharger, the AEM EMS is one of my favorite modifications. It is definitely one of the best decisions I made when picking parts for this car. The Jackson Racing Supercharger kit is commonly run on FMU, and some other electronic gadgets. A FMU simply adds fuel when it sees boost. That is not the greatest system, but it works. I decided to do it the right way from the start, and got the AEM EMS. With this system, I no longer have the need for any other electronic mechanism to control fuel, timing, boost, idle, nitrous, etc. This might have been an overkill for a supercharger set up, but now I have unlimited options |
| for future upgrades. I purchased the AEM EMS and AEM UEGO Wideband separately, so the most difficult part of this install was linking these two together. The first step is to disconnect the battery. Then you must locate you stock ECU. Mine was conveniently behind the passenger kick panel. Remove the plastic and expose the ECU. Unplug the harness connected to the stock ECU, and plug in your new AEM EMS. The directions include a wiring diagram for the wideband. You only need to | |
| connect a few wires, but make sure you solder them instead of using any other type of connectors. This may save you some serious headaches down the road. The next step is to connect the battery and power up the new AEM EMS. Make sure you have not already installed the 02 sensor as you will need to calibrate it. Following the directions you will now go through a series of simple calibrations like throttle position. This only takes a minute, and now you are ready to select your base map.

AEM EMS comes preloaded with several start up maps for your car. Pick the one that is best suited for your application. The best map for me was a turbo 440cc injector map. Once you load a map, must sure to scale the injectors if needed. To my surprise, the car started right up, and idled like a champ. The car was drivable, but I decided to have it towed to my tuner since he is almost two hours away. This was not a very difficult install, but there are a lot of little things that could go wrong and leave you with a |
| mess. If you have any doubts about installing a new ECU, I high suggest paying a little extra and have it professionally installed. |
