Injector dead time voltage correction in %. Why?

[sd1nl]

Was just turning my MS2 tune into a new fresh MS3 tune, then I got to the injector dead time settings wich got me wondering.

Why is the dead time voltage correction setting suddenly in %/V instead of ms/V? You have to get a calculator to get this right, even more so because every injector specsheet is in ms/V.

And when changing the dead time you have to recalculate everything again.

What could be the advantage of this?

"Suddenly" ? It's been like that for five years I think.

Like I said, I didn't use MS3 but MS2. it is still in ms/v in MS2.

But you honestly think it is practical?

I believe it's mostly done that way to make it easier to import MS2 tune files. They can just bring over the existing correction number.

what is the calculation to go from ms to %? thanks

To get percent of known values you must choose a constant. I always pick the 14v point as this and using that number as th divider, then use 14v spot on the graph is my 100% point. Now use the 14v ms number and divide it into the rest. I forget which is inputed first, but lower volts get a higher percent value and higher volts get a lower percent value

Multiply the base dead time by the % to get the dead time in ms.
