Hi,Sougata,

you're right ...

But the big problem is injectors are nor open 100% of the cycle !!!

a "100%" aperture equals, say, only 20 or 30 degrees at crankshaft ....

and this value has to be entered somewhere to measure something useful.

now, a simple "PULSIN" is enough to measure the ON duration in µs ... but maximal aperture ( vs. rotation speed ? ) has to be known to calculate a displayable percentage.

add to that needles inertia is not negligible at those timings ... and you'll see your measure is somewhat false !!!

Some data is missing here ...
