Dear Asad It is nice to see your project video. First, I would say that it is really good job being local and home made thing. You should contact auto makers here and abroad and get it used commercially. Second, I would suggest that you should run a few experiments using your EFI circuit and publish the results. For example, you may like to get fuel consumption data for a certain various loads on the engine, response of your EFI circuit when load is increased or decreased, acceleration it can support, etc.Further, you can compare the performance of your design with other commercially used techniques and point out the improvements, your circuit provides. Along with all this, you must improve your presentation as well as suggested by another colleague on the list. Best wishes -- Muhammad Farooq-i-Azam

| Hey fellows I designed & fabricated my OWN ECU for EFI Engine. its a Custom Made ECU, have a look at this This ECU has following features:
1) Adjustable Idling Speed.
2) Cold Start feature for better cranking in winters. Just starts in first Attempt.
3) Fully Controllable Ignition Timing (Advance/Retire) 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.
6) Fuel Pump runs only if Engine is running.
7) One can tune it for racing 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 more than that i made all this just for Fun, Engines r my Babies Best Regards Engr Asad |
