An engine control unit, also EMU (Engine Control Unit), can be freely programmable. With such control units, detailed interventions in the parameters of the engine can take place. Depending on the type of programmable controller, there are functions that are not available or possible with a standard engine controller. In order to change some fixed parameters, such a freely programmable controller is necessary. Then you can change all values. Examples of the variable functions include increasing the supercharging pressure from the turbocharger or changing the injection values of the injectors. Freely programmable engine control units are currently relatively cheap available on the market. Many, including well-known manufacturers, now offer freely programmable controllers and you get really good freely configurable ECUs at a very good price / performance ratio. Freely programmable control units with German-language software are also available.
Field of application of the control part
The ECUs support engines from one to twelve cylinders and offer useful gimmicks for fans of horsepower such as nitro injection control, a USB interface without the need for an additional interface, ignition and injection timing programming, and much more. A static ignition distribution, a sequential injection and / or a bank injection is also possible with some providers. There are also free firmware updates available that contain more and more features that many have always dreamed of. But it is important to pay attention to what inputs such a controller has. Freely programmable control units with an induction generator input, an encoder input, an input of the knock sensor, the lambda values, the air mass meter, existing pressure sensors, analog inputs and other freely available inputs are offered. Some ECUs are equipped with useful encoders, such as OT encoders or Hall sensors.
Also important are the existing outputs, for example, the speed, the injectors, the ignition coils, the servomotors and existing free AUX outputs. The basic configuration of a freely programmable controller naturally includes an interface for the PC and the function of saving the parameters. Some software programs also offer a display and a diagnostic function. An interface for data loggers is also standard with many manufacturers. The set parameters should of course be tested. For this purpose, a test stand is suitable. The starting behavior as well as the behavior under partial load as well as under full load should be validated.
Security measures and idea
With freely programmable engine control units, it should always be ensured that the configuration is gentle on the engine. Because you can manipulate the motor in any area with such a device. If no safety measures are in place, the engine of the vehicle is at risk from overstressing. The parameterization of a freely programmable engine control unit does not take place entirely without knowledge. Simply using the plug & play principle, nothing is possible with this system. There are relatively many providers such as Ecumaster, AEM, Link G4, Motec, Haltech and other providers of freely programmable engine control units.
Registration in traffic
If the vehicle is to be officially moved on the road, however, one should think twice about the stem of a freely programmable control unit. Normally, these parts are completely without registration and are intended for competition vehicle. Although a registration is not completely excluded, all individual approvals required for this will often exceed the entire vehicle value. We hope you the info report on the subject freely programmable engine control unit from the field of autotuning. Our goal is that the largest German-language tuning dictionary (Tuning Wikipedia) and to explain tuning terms from A to Z easily and understandably. Almost every day we expand this encyclopedia and how far we are already can you HERE see. Soon the next one will be Tuning scene concept be illuminated by us. Incidentally, you will be informed about new topics if you have ours Feed subscribe to.
