    Ah, sorry, I meant raise VE a little in those spots, and see if they go away.

    where back at it

    heres the tune file ive come up with

    we had a little knock on the high rpm right before rev limiter at 5860 rpm and 72kpa I believe

    what do you guys think? it was hard to keep it not jerky due to road conditions

    He has Dyno day setup July 27th I'd like to have mad turned on and all the other stuff.

    What would be best to copy and paste be and maf table over to stock files- or undo all my mods to do the calc.maft

    It's mostly good, a few places could be tighter, I see a few places where DFCO might be getting in the way...

    how is throttle response...?

    Snappy- crisp I thought

    When you say it could be tighter are you saying less spiky in the VE table?

    There are some places where trims and/or WO2BEN are out a little further... might be due to DFCO being enabled... I'm still looking.


    Throttle response being good like you said is an indicator that fueling is good which means VE and MAF are correct.

    Wonder if your seeing the part of when it up shifted when it was not supposed to!?! Had it in manual 1 and it went into 2nd twice on me when at light throttle going about 30mph

    And me out of frustration letting off throttle quickly? For maybe dfco to come on

    So what would be best to get this thing running off the maf again and PE settings staying or switching back also?

    Would it be best to copy over VE and maf to original? Then re adjust idle settings for cam.?

    Try this: drive it some more, keep an eye on PE fueling, make sure it is always sufficiently rich.
