Otherwise I'm going to step out for a bit and be back after while....
    Wow, i would have thought it would be more complex to tune a blower. Got lots to learn yet lol

    This what you are talking about doing for the refinement? Not sure if you caught it or not but i actually tried that with the BRAF table to dial in the 14-1600rpm column a little more. Greg, buddy, you are more than fine to step away if you want to. You've been a tremendous help and i cant thank you enough!

    Didn't mean it like that - wouldn't leave you hanging. Was just really tired and still had some other logs to go over. This one has the manifold volume increased and the VE table updated to a finer resolution. You'll have to dial the VE back in - sorry didn't do that in the earlier one...

    It's 11:45 right now. Think I'm going to hit the hay early tonight. Just glad she's working out...

    All good brother. I'll flash it, clean it up and go from there.

    Hey Greg! Car is starting to feel crisp and smooth throughout! I can definitely live with it now and i suspect it can be cleaned up even more with the VE and MAF tables. I do have a question though. Am I good to turn DFCO back on or do i just need to budget an extra $20 in gas money each week?

    Yes as long as you're happy with your fueling corrections. DFCO transitions should be smoother now too.

    Ok cool. I'll try to get another nice log and tune revision in the next day or so then turn it back on. Otherwise, It feels pretty dang good right now and about what I would expect from it, drivability wise.

    Attached is a quick log that i took today. This is where the VE & MAF ended up at. I'm sure it can be tightened up even more and maybe when I learn how to create a filter, i'll give it a shot but i'm pretty satisfied for now. Any objections as to why I shouldn't move on to spark tuning at this time or any tips, tricks, or comments on how to improve the spark tables?

    Looks good. Good smooth transitions. On the timing side you're already running more timing in the 1000 to 3000 range where cams typically want more. I would get rid of the idle high load area dip over to 1200ish rpms. Other than that you can play with a degree or two in the mid load area.
