    Nice! I plugged it in with another USB and it powered on. I was able to re-sync it so it looks like it's time for an upgrade!

    I'm having difficulty getting my shifts correct. I've finally got it shifting before the rev limiter kicks in, but now it still shifts way too late.
    I have the WOT shifts set at 6200RPM @ 51MPH...

    Got it! I knew I was missing something. Zeroed out Burst knock and bumped the timing up. Now just working on getting the last bit of KR out. Feels like a different vehicle.

    I only noticed this in the WOT runs.
    Throughout the tune, I've been using tap shift to hold third to get a lot of the cells populated, but there's no way without a dyno (or at the track) to get WOT...

    I finally got my Wideband installed and have made decent progress. :yay: The only problem I'm having now is in SD tuning going WOT, I can't do better than ~3% lean. No matter what I do (multiply,...

    Ok, looks like I'm going back to my stock tune until my wideband comes in. The numbers I'm getting are scaring me.

    I did the VE tuning then MAF calibration and PE to 12.8 (Stoich 14.3 for E10). ...

    Am I on the right track?

    Nevermind. I figured it out. MAF-STFT histogram was filtered for commanded AFR. I changed the stoich for E10 gas and it was falling below the filter. Back to the grind tomorrow.

    Yep, they're clearing up. I'm down to just the Evaporative System. Which in Texas we can pass with only one Not Ready. I didn't realize that every time you flash, it resets the Once Per Trip Tests.
