8.2. References and Background/Further Reading
Specific references consulted for this guide are listed below in order of section. The most useful single
technical reference is “Engine Management: Advanced Tuning” by Greg Banish. CarTech Inc (2007). ISBN-
13 978-1-932494-42-6. Although the author’s experience as an OEM calibrator is largely on U.S. vehicles,
and the terminology used and examples given are U.S.-specific, the basic principles behind modern ECU
operation on both normally aspirated and forced induction engines are very well covered and there are
plenty of useful tips and inside information. It should really be read thoroughly and fully understood before
attempting to understand ECU operation and any amateur tuning.
Another useful reference work is “Bosch Fuel Injection and Engine Management (Technical Including Tuning
& Modifying)” by Charles Probst, Robert Bentley publishers (20 Oct 1989). ISBN-10: 0837603005. ISBN-13:
978-0837603001 aid understanding of the basic principles of Bosch fuel injection systems, fault finding and
tuning.
