Abstract
This is the brief report of the development of a digital turbo boost pressure
controller. More and more of the modern cars features a turbo charger and they
are often electrically controlled from the engine control unit (ECU).
However raising the boost pressure of the turbo charger often offers a very
simple way of tuning the car. If a “boost up” is performed it is
important to keep track of the actual boost pressure, as well as controlling
it accurately. It might also be interesting to perform certain intelligent manipulation
of it.
This report briefly describes prototype circuit board and prototype software
that gives a baseline for interesting boost pressure control systems.
This work has been performed as the assignment in the course “Digitala
project”. For use in an actual car extra concerns has to be taken, and
the software has to be changed a bit.
Of course no claims can be held against any form of usage of this experimental
setup or the published information, neither of caused damage, nor of correctness.
