Hi All.

I have been looking around the internet with regards to my "Siemens Deka 1521390" fuel injectors, I keep getting two flow rates popping up "310cc/min" & "330cc/min".

Can anyone tell me witch is the right flow rate, and if possible what the test pressure and duty cycle is for the flow test.

One other thing I have been trying to find out but have been unable to, is what the "Injector Opening Time" is, I know that most fuel injectors are around 1.0ms.

Can anyone help me with this info?

Thanks for your time.

Best Regards.

opening time is the time taken between fully closed to fully open
