high wastegate duty cycle: why?

[F80RN]

I got my car at 42k miles, currently at 68k. I changed the plugs at 48k, and 58k. I just didn’t think of changing them before but I decided to get them done alongside a Crankhub. But since I’ll be pulling and replacing the O rings maybe I’ll replace the plugs and packs ahead of time.

Certainly not a bad idea and I can recommend the 97506 NGK's like many other members. At your boost levels I would keep the gap around .024~.025 as that has worked well for me under similar conditions.... If I were to swap the coils, I'd be looking at the Eldor coils. To my understanding the Eldor's listed for the N55 are the proper fitment for the S55. But it's worth some double checking on that as I have yet to have personal experience with them.

As I mentioned, the log I sent was the first log at E50; a new revision was sent which I’ve yet to flash and log

This is a log at E10 but I’m not sure how to accurately compare the timing as he looks at Corrections whereas yours has Timing per cylinder

These timing corrections are high but expected with octane limits in CA gas. What fuel do you use? I remember Bend telling me to stick to Shell or Chevron. What plugs are you running again?

Comparatively speaking when I was doing some pulls with low E content, my corrections were also 'high' but not unexpected for CA gas:

Gas: only shell. When I add Ethanol, there’s an Arco near me that sells Pearson. Bend mentioned that it’s evident the CA gas is bad based off the logs and corrections.

Plugs: NGK 97506. I change them every 10k miles.

What's the plug gap at? Honestly with Bend tunes you're going to do best with F8S plugs gapped at .019.

Here's a E50(ish) log with minimal correction. I have so many but there's an E55 one I have somewhere with 0...but just FYI.

Gapped at 0.24. Maybe that’s why?

I’ll also order those F8s plugs since I’m reading they’re good for flex fuel tunes

OH yeah that's way to big. .020-.022 max. F8S plugs are superior though so might as well just wait for those and pop them in when you do the rest of the items. Something I can also help with, easy. I'll sync with you offline.
