What's In The Kit And Why Do You Need It?
Note: The AEM Series 2 EMS is included in this kit.
WIDEBAND
Wideband kits are used to measure the Air fuel ratio of the car so that you can ensure that you have the correct tune for the air/fuel mixture.
Why You Need One
Wide Band O2 Sensors where developed in the early 90s as vehicle manufacturers began looking to obtain air/fuel ratio information under all circumstances. This ranged from WOT(Wide Open Throttle) to varying ratios, for example running air/fuel ratios leaner than 14.7:1(Ideal Air/Fuel Ratio for stock cars) under cruise conditions. High performance vehicle tuners discovered that wide-band O2 sensors are very helpful when accurate air/fuel ratio readings are required to maximize power, reliability, and mileage on modified vehicles.
IAT Sensor
The Intake Air Temp(IAT) sensor is used when cars are usually running MAF(mass air flow sensor) to convert it to speed density to work with the Map sensor. The IAT sensor converts the engine intake air temperature into a voltage and inputs it to the engine control module, which then corrects the fuel injection rate based on the input signal.
MAP Sensor
The MAP sensor provides instantaneous manifold pressure information to the engine's electronic control unit (ECU). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion.
Why You Need One
The MAP sensor is used when cars are usually running MAF(mass air flow sensor) to convert it to speed density. If the car is equipped with a factory MAP sensor the stock MAP sensor only has resolution up to about 22psi. Anything higher than that and the stock MAP sensor won't know what the exact boost pressure is. By installing an aftermarket MAP sensor, you now have resolution up to 3 bar (~30psi) or 5 bar (~60psi) depending on what sensor you buy.
Boost Control Solenoid
The boost control solenoid contains a needle valve that can open and close very fast. By varying the digital control frequency to the solenoid, the solenoid valve can be commanded to be open a certain percentage of the time. This affectively alters the flow rate of air pressure through the valve, changing the rate at which air bleeds out of the T in the manifoldpressure reference line to the wastegate. This effectively changes the air pressure.
Why You Need One
Factory boost control relies on a flimsy, inefficient solenoid. When boost levels are increased over stock, the factory actuators fail to properly meter boost. The resulting spikes, dips and erratic response can damage your engine and spoil the performance gains. An upgraded electronic boost control solenoid allows a much lower waste gate duty cycle to produce higher boost levels giving tuners better control and decreased spool time.
The Aem series 2 ECU was a breeze to install. It required a minor modification to the cam sensor but included all parts and instructions on how to do it. The interface was smooth and had some great features. Its on par with many of the ECU's of the same price range although the huge amount of plug and play sensors, gauges, controllers was made everything easy.
