Strange Idle - after fuel pump swap (E85)

abm89

I didn’t do the idle learn procedure in the video. I just did a cold start. If your car behaves the same way when cold, I think that’s normal man. I think if you posted a video of what’s happening it would help.

Good idea.

That's just the nature. Have same setup with same issues. Once your 100% 85 it will somewhat go away .seems like the computer is trying to read the content as its coming in.my car takes a bit longer to start once the engine is warm as well

So I’ve been running e85 for almost a year now, but my fuel pump is 2 months old.
I’m at 75% ethanol content.

Been retuned and everything.

You think it’s just the nature of the Z on e85?

Use smaller injectors?

Ok so I caught a smaller dip this morning - it tends to happen like this - and only a few times during the first 5 - 10 minutes of driving..

This just normal? It’s at just about 10 seconds - 15 seconds — something like that… It dips down to 700 and boosts up to 900
