2013 challenger with CAI, increase fuel at WOT?

[lloydhanna12]

I have read some in the forum about cars running lean with CAI's. Should I raise the fuel 5% throught the WOT
range? I'm running the 93 octane on my challenger. Its a manual transmission if that makes a difference. Ive looked pretty good on ST knock. Only about 2-3. Clears quick. No LT. The only time I saw more knock was WOT in 6th gear from about 100-120 mph.
I logged some ST up to 6. LT to 1. It went up and down 3-4 times in that speed range.

go ahead and add 5%.

Ok. I'll post log tonight. Thanks Mike.

Mike, Please take a look. 2013 Challenger RT Classic 5.7L Manual. Up to 120MPH. ST & LT look good 1st - 5th gear. I get some rare ST but clears fast. When I got to 6th gear , ST got up to about 6 and LT 1. Went up and down a few times. I increased fuel this afternoon like you said. I went to rich side 5% on all 3 RPM ranges. I'm not sure when I can do another 100MPH + run, but I'll log it when I do. Thanks again for all your support. I just want to make sure I'm running good. Also going to install a catch can, its on the way.

The modification I did to 93 Octane is +5 Throttle. Speed limiter to 190, set tire size.

I have a K&N CAI, Flowmaster American Thunder Catback.

With 5% fuel all 3 RPM ranges. A lot of ST in all gears

[lloydhanna12]

Back to 0% fuel all 3 RPM ranges

Is there a certain number of times you can modify a tune without reloading your original or resetting the default on the tune ? Or can you just continue to modify as needed?

[lloydhanna12]

Diablosport guys , did any of you get to look at my logs yet ?

[mikel]

going over logs is time consuming, its rarely something we can offer to do regularly.

if you are seeing KR, try better fuel, and add a little fuel until it goes away.

Make sure you have a catch can installed as well, or it will never go away.

Thanks

I am getting some ST knock. Mostly at higher speeds in 6th gear when rpm is low. If I down shift to 5th it clears up. I tried increasing fuel to 5% rich but it got worse. I use 93 octane exxon. I also installed a catch can today. I'm thinking about switching to the 91 octane tune. How much power difference between trinity 93 tune to 91 tune still using 93 octane gas ?

i just got my Trinity T 1000 and i'm trying to figure out how to get it to pick up that i have a CAI. It's only showing 91 and 93 octane. Not cai 93 octane or cai 91 octane. Is that a option on the Intune only?

From what I have read not all vehicles get a tune for cai's. I'm guess the cars computer adjusts good enough for the mod on some cars. My 2013 Camaro ss doesn't have that option either.
