I just completed a first pass at a web page on the analysis of the
D-Jetronic ECU:
http://members.rennlist.com/pbanders/ecu.htm
The page covers the following topics:
Introduction
ECU Operation Overview
ECU Photographs
ECU Schematics
ECU Block Diagram
ECU Circuit Block Analysis
ECU Waveforms
Common Questions and Answers
It still lacks descriptions of the operation of the engine speed sensor,
speed correction, and pulse width multipler circuits. I hope to add
descriptions of these circuits in the near future.
Any corrections, omissions, or clarifications are welcomed.
