    Add knock retard and your injector pulse widths into your logs, it's stuff you should be watching. Add cylinder airmass if it's not already there as well. See if you are picking up any knock or if...

    People that know GEN 5 stuff like to keep to themselves and I don't blame them. Big money is made on these things.

    Well, that sounds like fun.

    Do the basics I guess, like checking fuel pressure with a mechanical gauge.

    Even try disabling the MAF sensor and running it off speed density in closed loop. That...

    You can't write a P01 file into a P59 computer.

    The engine doesn't care what the calibration says, so being a van OS makes no difference. We have no emission testing in Minnesota so the VIN is not...

    Your other thread has that answer, the guy changed your tune file to run in speed density.

    Or wire the wideband into a 5v circuit on the computer like a lot of people do. Most use the EGR circuit and create a custom channel to log it.

    I haven't run into that problem yet. Did the same thing to a 2000 5.3 that had EGR and went with shorty headers because of space issues in a swap vehicle.

    When you log the misfires, how many...

    Part of it looks like an o2 sensor issue in closed loop. Bank 1 sensor is doing one thing while bank sensor is dropping out or reporting really odd values. That then cause your fuel trims to go crazy...

    A little high?

    It's right within 3% of zero almost all the time, that's more than good enough for me. I'd go straight to the MAF now.

    Even stock calibrations have that much swing in the trims,...

    Not sure if it'll do anything but try disabling the master enable/disable for the ETC cut off control.

    Cylinder 5 has a mean misfire too.

    Go for it.

    You could see if anything changes after open loop tuning with your wideband as well.

    You're missing your IAT sensor, that may have been built into your MAF previously. If you ditched the MAF, you'll be required to wire in a new sensor or wire in a new sensor if it's just plain old...

    If you get off the throttle and coast, which I did see in that log. It is normal to have them drop away, you can also watch your injector pulse width drop to nearly zero. The engine is entering DFCO...

    De-acceleration fuel cut off or DFCO is why when you are off the throttle and coasting it will peg the wideband lean. That is a stock function of the computers calibration. It saves fuel by shutting...

    Yep.

    They used their tuning device, so they payed for the credits then. Now you have a different tuning device, so you have to license it to that device, thus 2 more credits.

    No matter what it...

    Many people do this and it's not uncommon, they remove the o2 sensors completely and run open loop only and use a wideband o2 sensor to correct the fueling based on special graphs/chart they create....

    Seems odd that everytime you floor it the o2 sensors take a noise dive. Normally they should swing rich up around 880-930mv to show that fueling is there. It's not a super accurate way to judge but...

    Use paste special by half, you are making too big of changes at once. Look at the 3D view, there are so many huge spikes that it's tossing your fueling all over the place. Probably want to start over...
