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

what rpm does the kr start at?
should only need to add more fuel inthe middle rpm range, try that.

[Peter_beresky]

It's looking like right around 2800 rpms

Ok I figured it out. I had to add a lot of fuel to get it to not knk. I also put better fuel in the car. Here is what I had to adjust too:
WOT. Knk st. Knk lt
1000-3800. :13. 0. 0
4000-4800. :11.5. 0. 0
5000-7000. :9. 0. 0

looks like the TB may have leaned it out a bit, along with the CAI.

[Peter_beresky]

Yeah it did.

I just found the misfire cnt parameter and it reads out at 4-5 right after i plug it in and the engine is already running and after about 10 minutes of driving its as low as 6 and as high as 11! Any ideas on how to fix this?

[mikel]

misfires are not caused by a tune....put it back to stock, I bet they are still there

[eric.hauptman]

I'll try that is there any tuning i can do to get rid of it?

[Mike_Levy]

Misfires have nothing to do with tuning. Its either a plug or coil issue.

[eric.hauptman]

I noticed that the misfire count is a lot higher when it's cold it was up at 16! When it go was warmed up it was at 4

[mikel]

makes sense...

[eric.hauptman]

I was wondering if there was any monitor guages that could be set up for data logging to determine where the misfire is coming from?
