SeBCON-µC v2.0 (Stoni's electronic Boost CONtroller)

Let's have a look at the improvements of SeBCON-µC v2.0:

SeBCON-µC is a electronic boost controller for engines with any kind of conventional regulated turbochargers and electronic fuel injection. The aim of SeBCON-µC is it to handle drivability and economy on part load as well as excellent top power in high pressure applications. Therefore SeBCON can handle several input signals, is able to do calculations with them and generates a solenoid pwm output signal via a highspeed power stage to control the boost.

Main function:

SeBCON is a air mass based boost controller, using the amm signal as primary signal to calculate the boost hight. SeBCON analyses also the injector duty cycle to know always the exact engine load. This makes it possible to provide the boost control valve with a separate value for every engine load point. Analyzing the amm signal and the injector duty cycle gives a much better throttle control then conventional systems which gives you always maximum boost, even if you don’t need the boost.

If there is a problem with the boost level, e.g. to much boost at a specific rpm, than it’s possible to reprogramme the map. Knock detection works adaptive and self-controlled. After a knock ocours, SeBCON adjusts the boost in that way, that it will store per every 75rpm the maximum of boost which can be run savely. If the target boost value is higher than the as save considered value, the save value will be used insteed. While knock ocours the boost will be corrected 5 times per second, downward in steps to 0.010-0.015bar.

The real knock detection must be realized with an externel tool or by using a existing knock modul like e.g. the Bosch EZK116 ignition box, SeBCON uses a existing signal to control the boost - SeBCON has no own input for a knock sensor.

The advantages of using the amm signal and injector duty cycle for boost control:

- better throttle control
- better fuel economy
- boost proportional to throttle position
- cruise control compatible
