Arduino Mega powered ECU for diesel engines using Bosch VP37 (or inline) diesel pumps.
2013-06-06: Update! Engine running in car. Now finishing V1.0 design ...
2013-04-24: Update! Installing test engine to the car has finally started.
Work in progress, basic functionality currently implemented:
- Live configuration interface over USB (serial communication using any terminal program or dedicated debugging counterpart)
- DTC memory
- Analog feedback actuator supported, inductive (HDK) style in progress
- Fuel Map (RPM vs. TPS)
- Cold start and idle map (RPM vs. Temperature)
Download Release-1 from here. Example sensor data to proof sensor signaling (WAV file with left channel is needle lift sensor, right channel is VR sensor on flywheel).
Download Monitoring and Debugging counterpart here (Open using processing environment).
Wiring diagram under contruction. See below for simple schamatics. It uses two FETs and 2x LM1815 for signal shaping.

Quick test run
Test engine installation
Configuration interface screen captures
Connected to DMN-EDC over serial connection from laptop. Showing: Main menu, Fault memory, Adaptation/Configuration and Map Editor.
Debugging and Monitoring software
You can also connect to DMN-EDC with EDCstimulator, which provides graphical view what's happening inside. Showing: Generic meters view and PID control history, Data dump for every calculation cycle for about 1 sec, and built-in terminal emulator.
