The Trionic 5 Box Controls the Internal +12 Volt Regulator

Analyzing Trionic 5 with T5Suite 2.0 Trionic 5 © Dilemma & J.K. Nilsson 2010 rev 1.23 Analyzing Trionic 5 with T5Suite 2.0 Preface This document is intended for Saab fanatics and engineers who want to start understanding the Saab Trionic 5 engine management system. It will give as much information as possible about the technical part of the system. The only limitation will be the knowledge of the author. In short the content of this document will enable you to understand Trionic better and give you hands-on information about altering the maps it uses. Prerequisites are minor electronics and computer knowledge and of course some understanding of how a turbo charged engine works. Throughout the document the T5Suite software will be referenced. This software will enable you to really “get into” the Trionic. The T5Suite software can be downloaded from the T5Suite website. http://trionic.mobixs.eu Acknowledgements The author would like to thank everyone on ecuproject for their help on getting all this information together. Special thanks go out to General Failure, J.K. Nilsson, Hook, Hma, Vigge, Mackan, Renton, Sourcode, Seb, Sandy Rus, JKB, L4staero and Steve Hayes.
