I have looked into this for you.
Hardware 12 bits (vertical resolution of 4096 steps) will be able to see alot more detail than the 8 bit scope (vertical resolution of 256 steps). Adding the software enhance will not increase the number of steps the scope can capture, its more of a filter.
However with an injector waveform I believe it should be OK to give you an idea as to whether the injector is behaving
Resolution enhancement is a technique for increasing the effective vertical resolution of the scope at the expense of high-frequency detail. Selecting resolution enhancement does not change the scope’s sampling rate or the amount of data available.
