I replaced a fuel injector in cylinder 6 with new decoupler and teflon seal. Car no longer shows a super knock code. I filled from almost empty to full at chevron but did not notice the ethanol content until I was looking at the log. The log is all the way up in second and I did not stop the log at the top. I stopped it after decelerating and shifting. I did the log on a road I was not completely familiar with. The ethanol content had not dropped to under 10 percent when I started the log. It was still going down. The car pulls very well. The LTFT and STFT are triggering an CEL on the dash now. The seam to climb above 25 when cruising. That is when the light triggers. Throttle response is good. It is a very linear pull all the way up. The car does sound like it is breathing when holding fixed speeds. It may have always made the sounds but with the stock location inlets I did not notice as I do with the relocated inlets. I do not know how to confirm the second in tank pump is actually ramping up. The NOS solid state is wired to Aux 2 on the Motiv and line pressure as well as hpfp pressure are able to climb and seam to maintain when accelerating. Is there a way to check?
