Taking a stab at answering my own questions after further research. Or providing more info for discussion at least.
For the table labels issue, at least for the injector tables, im deciding that the labels dont matter, and that the sensor offsets that are also entered elsewhere invalidate the labels on the table. I am wondering if there is a way to update the labels on my tune to match the zl1 labels. Once the sensor offset values are changed, im thinking the labels are in reality incorrect. In other words, once the lt4 inj values are all entered, the 21 MPa column on the lt1 tune is actually for 28 MPa despite the label.
Not sure yet what factors go into the spark airmass calcs and subsequent table scale. Main concern is forgetting that the labels dont matter.
For second question on SOI... thinking ill leave as is, where soi is moved earlier from stock. My understanding is lt4 injectors only flow about 15% more fuel, and while the overhead the the SOI change provided might not be needed at my current power level, that overhead will be consumed by future mods. I dont know enough about SOI impact on injector injection windows to be confident in messing with it too much. I know with SOI moved earlier inj pw window is 6 ms max, guessing that in original SOI config its closer to 5 or 5.5 ms.
