2012 Challenger R/T with K&N CAI, 85MM throttle body

[Peter_beresky]

Sorry to bother you and I hope this isnt a stupid quesiton. I have a 2012 Challenger RT 6 speed Manual. My mods include K&N CAI, Arrington 85mm throttle body, flowmaster 40 series exhaust. I currently have the 93 Octane tune loaded. I also have a 08 mustang gt with the canned CAI tune installed and I know more fuel is added for this tune. So my questions are, do I need to adjust the fuel on the trinity 93 octane tune? If so, how and how much? Do you plan on releasing canned tunes for 85mm TB and CAI, roughly when? Thanks for your time.

I'm not sure if this additional info will help answer my question but it definitely concerns me.
Fuel-93 octane
Engine temp-195
Outside temp-42
Now thae numbers were from a 16 minute drive:
knk fuel retard-highest recorded #-7
Knk lt retard-2
Misfire cnt-1

[Peter_beresky]

Just did another log.
This time the max numbers were:
Knk fuel retard-9 deg
Knk lt retard-4.5 deg
Misfire count-0

What brand of gas are you using? Thats way too much KR, and adding gas may make it worse if its garbage like Shell or some no name.

[Peter_beresky]

Citgo, I'm pretty limited on gas stations in my area.

[Mike_Levy]

Try adding a little fuel in the ranges where you're getting KR. If it helps then the gas is fine. If it makes it worse, you gotta try to find another brand.

Just spoke to mike on the phone about 20 minutes ago. Told me to try the 91 tune. I did and here's my results.
Knk retard-7
Knk retard lt-3.5
Misfire count-7

[Mike_Levy]

That helped a little, not much. Its gotta be the gas. I'm also wondering about those misfires.

[Peter_beresky]

I actually think it made it worse. It was worse than my first log with 93 but better than the second. Also it had 7 misfires.

[mikel]

thats not the tune....I bet it shows misfires with the stock tune as well....

[Mike_Levy]

Yeah, but why is it misfiring? I never had a single misfire on either SRT8. Thats gotta be either the plugs or coils. Are they all on 1 cylinder or is it a random?

could be a VVt thing....

[Peter_beresky]

I have adjusted fuel in the 91 tune but still misfiring. On the 93 tune I am getting no misfires.
I started increasing fuel under the wot setting a 2 percent. I'm now at:
1000-3800-4%
4000-5000-5%
5000-7000-5%

Knk retard-3.5
Knk retard-1
Misfires-0
Is it safe to increase to more fuel, or is there another suggestion? I appreciate all the help so far.

[mikel]

i highly doubt it was misfiring at WOT....add a little more fuel to quench the KR.

[Peter_beresky]

Ok I did. I am now up to 7.5 for all 3. Here's my results.
Knk retard st-3.5
Knk retard fuel-3.5
Knk retard LT-0
Misfires-0
