For fans of performance enhancements, there are many ways to increase the series performance of the car by a few interventions. One of these options are freely programmable injection systems and programmable ignitions, for example with the proJet Basix +, the basic model of the established Projet series. This is suitable even for beginners and offers some advantages. It should be mentioned here that the programming is easy to understand and takes place in German. There are relatively many providers of freely programmable injection systems and ignitions available. As a rule, the devices work with an 2-channel bank injection and are suitable for four-cylinder engines. Of course, modules for engines with more than four cylinders are also available. Modified distributors (Photocell, impeller) or Hall sender used for control. An alternative would be the control via the built-in breaker.
The reasonably priced base modules also offer a relatively high number of interfaces as well as inputs and outputs:
- The possibility to control via photocell.
- Input of a Hall sender
- Signal from the OT sensor
- Input of the signal from the throttle potentiometer
Furthermore, the devices offer the possibility of saving parameters on the PC. In addition, diagnostic and display functions are provided. The modules come of course with the appropriate software and these are available in many providers in German.
Inputs of freely programmable injection systems and the ignition
There are more inputs than mentioned above. As a rule, the following inputs are already available in the basic modules:
- Input of the sensor for the temperature of the engine.
- Input of the sensor for the intake temperature.
- Freely available inputs for further temperature sensors or sensors.
- Input of the signal from the throttle potentiometer.
- Input of the signal from the hot-film air mass meter.
- Input for the signals of the lambda probe as well as for the broadband lambda probe.
- Input for lambda control.
Possibilities of data processing and programming
The modules are programmable as the name implies. For some modules, usually not in the base modules, you can also program the response of the lambda values. There are also several tuning ranges programmable. But even this feature is not usually available in the base modules. The function alpha / n, which is controlled by potentiometer of the throttle valve, is usually included as well.
The basic modules are already equipped with the necessary interfaces. The most important interface is the PC, where parameters and injection maps can be stored. Data can also be recorded on the PC. These functions are also usually offered in the basic modules. These modules are also equipped with an interface for a data logger.
Outputs for the ignition
The ignition outputs are usually not available in the base modules. Outputs for this are, for example, an output for the relay of the fuel pump, an output for the LED display of the pump output and / or an output for the warning lamp.
Freely programmable controllers are not for laymen. Without experience and knowledge you can destroy a lot of things. We hope you the info report on the terms freely programmable injection system and ignition 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.
Below are a few examples from our tuning lexicon:
But of course tuningblog has countless other articles on the subject of cars & car tuning in stock. Do you want to see them all? Just click HERE and look around. But we also want to provide you with news outside the tuning. In our category Tips, products, information & Co we pick up contributions from car or accessory manufacturers. And also our category Test sites, laws, offenses, information has almost daily new information for you. Here are a few topics from our tuning wiki:
"Tuningblog.eu" - we keep you up to date on the subject of car tuning and car styling with our tuning magazine and present you the latest tuned vehicles from all over the world every day.
