    you had 2 spikes of 3 or 4* in like 2 cells, you can take out timing in those 2 cells, but im not sure if it will help or not, not a ton you could do about that IMO. If there was KR all over the place I'd be worried but 2 or 3 frames of kr out of 6500 frames isnt horrible especially considering its transitional.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    Thanks for the info. I am not hearing any pinging I just wanted to make sure that things looked ok. Got a lot to learn that is for sure.

    Thanks,

    I agree. You have no KR issue. AFR is very rich in PE though.

    It's hard to tell and honestly you weren't in PE but a very short time during this log. At about frame 4800. You were commanding 12.9 AFR and were getting 10.7. Fuel trims weren't that rich... I'd say VE needs work. Unless things work different with an LS2 (I assume) you are also very lean at idle. LTFT's have learned +18% during idle. Might have to be this way with the cam.

    Hopefully somebody with experience with these beasts and LARGE cams will chime in if I'm all wrong here.

    Very good dyno #'s by the way!

    Use this config file, as you were not logging Maf Hz. And the histograms will now work for you. Did you apply the Maf patch? Post your latest tune file.
