Check engine light on 2011 RT Limited/rich in both banks

This is my first post and if this has been covered, I apologize.

First, this is not meant to fuel (yes, total pun intended) the fiery debate about ethanol vs. ethanol-free fuel. My wife and I just picked up a 2011 RT Limited. When we purchased it, it just got back from the shop. It had been sitting, waiting for parts, for about 9 months with 91 octane ethanol fuel in it; I'm sure it gummed some things up. I ran than fuel out and filled it with 88 octane ethanol free. After about 20 miles the computer freaked out and the check engine light came on. We took it home and the 2 codes that popped up are P0172 and P0175 - rich in both banks; that makes sense because the bike has never seen that fuel before. What I'm wanting to know, is how long it might take for the computer to relearn the new fuel and recognize it as the new normal. The machine has about 80 miles on it since the new fuel and the check engine light is still on and the codes are still the same 2 that I originally got. The machine is running better as we cycle more fuel through it. Has anybody else had this experience and how long did it take to clear up? I need to run a fuel system cleaner through it still. I know Seafoam is usually the go to for carbs, but what's the go to for these fuel injected machines?

Once again, I don't want to get into the debate about ethanol vs. non-ethanol fuel. I'm just asking what other peoples' experiences have been in this situation.

"88 octane fuel", do a search on the internet on that, make sure that is not what you are running. If you are running non ethanol fuel it will run fine with no issues. You may have other issues like fuel filter or vacuum lines. First make sure its not 88 octane fuel that will do what you described.

I have owned three Spyders over the past 12 years ... they have been fed 87 Oct. with ETHYL .... I haven't had any issues. .... Run a can of Sea Foam thru it and :agree: with CopperSpyder
