NA Nytro with Bolt Ons, AFR readings help

[Tvatcher700]

Hey what’s everyone running for AFR on there nytros?
I have full hindle exhaust, K&N intake with PC5 and Autotune. Right now I’m running 12.8 full way across the map. But finding it studders/pops when accelerating. So I been thinking I’m gonna try running 13.2 AFR at low Rpms. (500rpm-6650 2%-40% throttle) and (6670-9500 rpm 45-100%) afr at 12.8 see if that will make it any better. I Am getting black gas clouds when accelerating now at 12.8 full way across map.

The autotune doesnt work properly on these sleds for some reason, it keeps making your tune richer. Plug the PCV into your computer, and shut off the autotune, should run much better.

Did you buy from hurricane? He should have a PCV map that works perfectly with the hindle.

Ulmer and Dave at hurricane both have good maps. Check out this.

I have tried both of there maps. Sled ran very rich on both maps. I guess it’s because it’s base maps for all the sleds. Not tuned pacifically for each sled. Since all runs a bit different.
There maps in my sled the afr stayed around 10.1-10.5 AFR

Autotune has been working for me. I have ulmar base map in and autotune running at 12.8 has been taking a lot of gas away, and sled is running better. But still bit to rich. Here is a picture of the autotune running on ulmar base map.

Mine definitely runs stronger the colder it gets. May bite the bullet for the auto tune this summer. Runs like a stuck mule around 0 deg.

My personal experience with autotune is awesome, nytro is runing much better, and my gas milage is way better. takes awhile to do though.
