The AEM Fuel Ignition Controller is a popular aftermarket performance part designed to increase horsepower and torque in high-performance vehicles. The controller allows for complete control over fuel and ignition timing to optimize engine performance. However, installation can be tricky if you are not familiar with wiring diagrams. In this article, we will provide a detailed guide on the AEM Fuel Ignition Controller wiring diagram for easier installation and optimum performance.
What is an AEM Fuel Ignition Controller?
The AEM Fuel Ignition Controller is an aftermarket performance part that allows you to adjust the fuel and ignition timing in your vehicle’s engine. The controller works by intercepting the signals between the factory engine control unit (ECU) and the fuel injectors and ignition coils. This allows you to fine-tune the fuel and ignition timing to suit your specific performance needs. The AEM Fuel Ignition Controller is ideal for high-performance vehicles that need precise control over fuel and ignition timing.
How does it work?
The AEM Fuel Ignition Controller works by intercepting the signals between the factory ECU and the fuel injectors and ignition coils. The controller modifies the signal to adjust the fuel and ignition timing. This allows you to increase or decrease fuel and ignition timing based on your engine’s specific needs. The AEM Fuel Ignition Controller can also modify fuel and ignition timing based on other factors such as engine temperature, air intake temperature, and throttle position.
What are the benefits?
The AEM Fuel Ignition Controller has several benefits, including:
- Increased horsepower and torque
- Improved throttle response
- Better fuel efficiency
- Greater control over engine timing
- Ability to fine-tune performance for specific needs
Wiring Diagram
The AEM Fuel Ignition Controller wiring diagram can be complicated, but we will break it down into easy-to-understand sections. Before getting started, it is essential to have the following tools and materials:
- Wire crimper/stripper
- Soldering iron/solder
- Electrical tape
- Heat shrink tubing
- Wire loom
- Zip ties
Step 1: Power and Ground Connections
The first step in the AEM Fuel Ignition Controller wiring diagram is to connect the power and ground wires. The power wire is typically red, and the ground wire is typically black. Connect the red wire to a switched 12V source, such as the ignition switch, and connect the black wire to a good ground.
Step 2: Sensor Connections
The next step is to connect the sensors to the AEM Fuel Ignition Controller. The following sensors should be connected:
- MAP sensor
- IAT sensor
- TPS sensor
- Knock sensor (optional)
Each sensor should have its own signal, 5V reference, and ground wire. Use a wire crimper/stripper to connect the wires to the corresponding pins on the AEM Fuel Ignition Controller. Secure the wires with electrical tape, heat shrink tubing, and wire loom.
Step 3: Fuel Injector and Ignition Coil Connections
The final step in the AEM Fuel Ignition Controller wiring diagram is to connect the fuel injectors and ignition coils to the controller. The following wires should be connected:
- Fuel injector control wires
- Ignition coil control wires
Use a wire crimper/stripper and soldering iron/solder to connect the wires to the corresponding pins on the AEM Fuel Ignition Controller. Secure the wires with electrical tape, heat shrink tubing, and wire loom.
FAQ
Q: Can the AEM Fuel Ignition Controller be used with any vehicle?
