    That tune is pretty agressive with timing. Started to get some knock at higher RPMS and I am working on that. I was wanting to see if some of you guys can look over the o2 volts and LTFTs to see if there are any problems so far.

    Thanks!

    LTFT is dead on @ WOT. Gets pretty out of whack in cruise.

    I thought you only saw a Pulse Width reading on bank 1?

    Low injector duty cycle.

    O2s about where they should be, but I'm always skeptical of those.

    MAP seems a bit low, but that's probably from the environmental conditions and/or altitude.

    Same goes for MAF.

    Bit of KR like you said.

      Yeah it started working for whatever reason.
      Injector duty seems ok, but lower than what most see.
      In colder conditions, I took another log, the KR is gone, so I made some adjustments to the ECT vs Spark and IAT vs spark so It will pull a little timing when its hotter.
      With IATs under and around 70* the MAF is about 1-2 lbs-min higher. MAP is higher too. Injector duty also goes up when its cooler. I see 83-85% when its cool.

      I will post the log of the cooler run when I get home in a few....

      Thanks for looking it over.

        In your bin. file I saw that your high oct. and low oct. are the same. I would -4 from the high oct. and copy and paste it to your low oct., just in case you get bad gas or something.

          Also if your not running a cat on there you can set your COT at 255 deg.

            I have a cat.
            I have the table copied in both so I can tune the high octane table for sure.
            When I am done, I will just put the stock table back in the low octane (or something minorly changed) as I don't need a ton of timing if I am running cheap gas.
