Hello Guys,

i made my own Engine Control Unit ECU using PIC Microcontroller
have a look at it

http://www.youtube.com/watch?v=K_fpNcJUpcQ

This ECU has following features:
1) Adjustable Idling Speed + Idling Speed Regulation.
2) Cold Start feature for better cranking in winters. Just starts in first Attempt.(Batch + Sequencial Injector firing)
3) Fully Controllable Ignition Timing (Advance/Retard) no need for Advancer in case of CNG.
4) Injector Duty Cycle is Programmable (Rich/Lean).
5) Cooling FAN can be set at any Temperature. to run the Engine at Optimum Temperature for maximum performance.
6) Fuel Pump runs only if Engine is running.
7) One can tune it for High Performance Vehciles to extract maximum output from the Engine.
8) It can be set on Economical Mode for Extra Fuel Saving.
9) Engine Maximum RPM can be limited at any set point. To enhance the Engine Life.
10) Injectors can be disabled just by giving one Pulse so there’s no need of Emulator for CNG.

ECU Inputs:
Intake Air Temperature Sensor, Throttle Position Sensor, Manifold Absolute Pressure Sensor, O2 Sensor, Oil Pressure Sensor, Knocking Sensor, Coolant Temperature Sensor, CAM position Sensor, Crank Angle Sensor, VVT Feedback Sensor.

ECU Outputs:
3-Fuel Injectors, 3-Ignition Coils, Idling Air Control Valve, VVT Solenoid, Purge Valve, Radiator cooling FAN, Fuel Pump, + RS232 port for Data Monitoring

Best Regards

LOL @ The video, engine seems to be missing a piston, though, I can only count three! ;-)

What do you mean by feature 4? And 8?

I don't understand 10 either.

What are "advancer" and "emulator" for CNG?

Given that this is in the open source section, where is the source code and which license have you or are you releasing it under?

Welcome to the board! :-)

Fred.

PS, it's Retard, not Retire for timing.

Respect on doing it on a PIC16F, that thing is like 10 MIPS. Nice android app, you managed to put in alot of info on a single screen.
