This project is not new, it started a while·
ago when I and my friend we decided to
make an EFI system.
Initially the system was based on a PIC18F452.
was functional but had some problems that were difficult to find, and·
very limited RAM.
But when I found the propeller It felt quite obvious to upgrade to it.
The propeller is perfect for an engine management system, with true multitasking, it will be much easier to succeed with
Here is a picture of the most recent prototype:
Now we have a prototype that works very well, but lacks a few features that we're working on right now.
The system is similar to other aftermarket engine management systems.
The ECU will have support for 4,6,8 cylinder engines to begin with.
The ECU controls both ignition and fuel.
16x16 matrices for Ignition, VE, Lambda. with interpolation.
Measuring water temp, air temp, TPS, MAP,·
EGT x 2, Battery voltage, RPM, Lambda, etc..
Manages 60-2 Trigger and HALL Trigger.
a data log function.
Control idle with both the PID controller and ignition timing controller.·
Waste Fire / normal fire.
plan to add some unique features
The software is written in C # and works well, but is far from finished.
I have also made simulator engine that really has simplified the development of the system.
Recently, we've run a motor in a·
engine test bed·
with very successful results.
Now it seems that all the basic functionality works as intended.
Here is a short video that proves that is works:
