    Finally purchased a WBO2 and then finally got it installed last weekend. Fits perfectly in my suburban's ash tray! Kind of cheesy, but I like it because I can close the ashtray and not always see it. Sorry for my upside down pics, not sure how to fix that (it's a mac thing) IMG_6481.jpgIMG_6482.jpg

    I have not had much chance to do any tuning with it. And of course as mentioned earlier, it's just a visual tool at this point, not feeding its output into anything other than my brain, and it doesn't sound like my '7060 has an available input for it. But even with just the visual, it's pretty obvious to me what is going on with my odd surging during decel - gauge is pegging lean in perfect rhythm with the surging so seems like getting a fuel cutoff even though DFCO is not being triggered. More research and data logging required, I guess.

    Yep, I've done that same thing but it was a time issue last night when I posted.
