Injector duty

[Mondorno]

Hi,
is the injector duty stored in the factory ECU? So I can read it out with a Blitz R-Vit?
How else can you measure the duty without a avc-r or something like that?

Easier question: Is injector spraying time the same as injector duty?

 

[andyc]

spraying time should be in milliseconds

you need that info and rpm to calculate duty

the injector will squirt every 2 revolutions so

8000rpm is 8000/60 = 133.3 rev per second = 66.6 squirts per second

so time available for 1 squirt is 1/66.6 or 15ms

if your injector time is 12ms duty is 12/15 or 80%
