Just curious if scaling a tune affects the reported inj dc.

It is accurate. Just a function of the time the injector is open and engine RPM.

IDC remains true. On E40/E38/E67 applications though, it does not take into account voltage offset, short pulse adder, or the mandatory 0.800 reset time between pulses.
0411s include the offsets in the displayed IPW, but still don't do anything about the reset time in the calculation.

So here is why I ask. I have a stock cube GTO I am working on with a 50% scaled tune for 110lbs/hr injectors. The car has heads, cam, and tvs2300 @ 8-9psi. The scanner is showing 96% inj dc. I have a hard time believing that even with using e85.

That does seem odd but I donno, could be. I have 1k injectors and while I'm running a lot more boost and cubes I'm also spraying a lot of meth and I still saw 88% at the track recently. If yours is running really fat on E85 I don't think it's an impossibility.

Did you consider that your injectors might not be what they say they are? What's your engine speed and injector pulse width when you're seeing that IDC?
