Using LABVIEW To Read and generate pressure for fuel injection

[jamran]

thanks mate. i really do appreciate you help. thank you very much! jus one more thing the power drive also can control the fuel pump, so is there a reason y i shoulld still use a pid controller?

It depends if the power drive has the pump control built into it. The PID controller is required to maintain the rail pressure at the desired setpoint. As you change the injection quantity/ timing, number of injections, these affect the rail pressure so that a constant PWM signal wouldn't work.
