What are the emblems? I'd be curious on that. Factory is set to 12.0 but COT is in the 10s for AFR.

I never paid attention to the AFR when stock. So your saying 10.5 is what the factory tunes them at?

No, factory is 12.0 but once the cats get hot there's a modifier called COT (cat over temp) that kicks in more fuel and it'll be in the 10s. On a stock car this usually happens mid way through 3rd gear at the drag strip if memory serves. I've got that turned off on mine and so do most other custom tunes.

Curious what ever came of this. Did you tuner change something? Or are you switching? Or keeping it as is?

Think I'm going to send the tuner another data log. Just to make sure he's happy with everything.

I'll let you know

Stoich is 13.85 on the hc. Not 13.65. Low to mid 11s on the dash is fine. I run e85 100 percent of the time. That comes in at 10.9 to 11.1 on the dash. If you are at 10.5 from 3500 rpm up you are running way too rich on pimp fuel.

10.9 to 11.1 isn't pe fuel for e85 fyi. Must not have stoich reprogrammed for ethanol.

I never said stoich was 10.9 to 11.1 on e85. I am running 10.9/13.85. So FYI try to read a little better. Or maybe make one or more of your lame ass videos.

It’s called Lambda. You seem to think you have tuning skills. Be carful there. And try to comprehend better before posting. And yes your videos are lame.

This is only about sharing information folks; no need for personal attacks. If nothing else, such talk only undermines whatever possibly valid point one might have. It's very easy to come across as more offensive than one intends on line in a written medium (so much of human communication is inflection, tone, body language, etc...). If you reread that and intended to give offense, then have at it, but I see no need for it, personally, and it detracts from the usefulness of the forum and from having free and useful discourse.

My 2 cents. Or 55 with inflation. Take or leave it, or don't.

I’m not here to argue but I do want to make sure the correct information is being shared. More people are reading these posts and trying to learn about their car than just people who are active members on this forum
Also I think discussion is a great thing if people disagree on a topic. As long as it’s done the right way. Sometimes all parties end up learning something when there is supporting information on a topic.
Here is a post by dusterhoff tuning. https://www.hellcat.org/threads/attention-all-modified-hellcats-running-e85.230179/

Again I did not state the stoich is 13.85 for e85. Speedy does not know what the heck he is talking about. He states things I have never stated. Any one who makes lame ass videos as a substantial part of his life has problems. I have never liked the little guy and never will. A little power trip guy.
You tune in lambda. It is perfectly fine to leave the preprogrammed stoich at 13.85 on the hellcat. The stoich for e10 is 14.1 or so. So the engineers at Chrysler messed up? No they did not. Because tuning is done in lambda.
Tim Barth my tuner left the stoich alone at 13.85. It is fine. Dusterhoff is not God. A lot of tuners leave the 13.85 in there.
OP, your lambda is too low for pump fuel. 10.5/13.85 is even a little low for e85 which has different lean and rich maximum powers than pump fuel. You are leaving power on the table and if tuned at partial throttle too rich you can foul your plugs.

Bingo @jonx96 guess what my dash reads at idle on E85😎 I wouldn't say using the injector method is wrong per se but I wanted to set mine up as if it were factory tuned for E85. Takes a bit more work bur worth it IMO.

Plus when you have tunes for pump gasoline and E85 you'll know which tune and fuel is in the car by what the dash gauge reads.

If only we could change the dash to read lambda. The car actually reads lambda and converts to afr so woulda been an easy option.

I can see this being confusing for people new to these concepts. Gives me a content idea for another lame ass video:ROFLMAO:

Go argue with Chrysler. Be carful of this guy. His emojis and his little power trip can have you blowing up your engine. Speedy made a video back in time where he changed his tuners tune and proceeded to blow up his engine. The guy is snake oil.

People like you are actually why those who "know" don't post on forums much anymore. They get tired of arguing things with people who don't understand them. Curt, AJ, Tim, and many other very knowledgeable people used to be very open with information but you rarely hear from them anymore and this kind of BS is exactly why.

OP never asked about Lambda, isn't running E85, and probably doesn't even know what Lambda is. He asked about his dash gauge reading at WOT on pump 93 gasoline. Maybe YOU need to learn how to read and realize you piping in with irrelevant and incorrect information isn't helping anybody. This crap is confusing enough for the average person as it is.

I'm not gonna argue on the internet anymore, but that's strike two for insults. One more and my little power trip will recommend a vaction for you.

Then do not state things I never stated. And do not act as though you know things when you do not. Your learning is dangerous for other members when you make those lame ass videos. Don’t assume you are smarter than others. The op sounds pretty intelligent to me. Signing out as I have a good day ahead of me. Go make your video!
