    I wish more people would dig in and work on alternatives/solutions. So far the changes I've made have been very stable though. Enough so that I don't have the energy to invest more time in the o2 sensor game.

Net net it's good enough but would be nice to find a way to convert the car to a single bank and run one wideband post turbo some day.
    Check this link out Terry. I found it informative.

    Interesting data point. I would have expected to see some split between pre and post turbo readings. Tks.

    If that area were my cup of tea, I would gladly look into it. I'm more of a mechanical kind of guy. I hate electronics. Not trying to criticize you. I know you would do it the "right" way if the option was there right now.

    No offense taken. Like Andy I suspect we find something that works and decide improving it isn't worth the effort. For example we've programmed the JB4 to reset lambda adaptions each time the car is started to keep the banks from diverging over time (CANbus FTW). But that isn't to say a better solution doesn't exist. Hopefully more people dig in to this.

    On what version/firmware did this go into effect? The Lamba adaptation reset?

    Its not out yet. I think He's still testing it. 11_6 IIRC will be the hex rev
    Formerly 3000GT MR

    Have a single turbo and/or tired of burning up O2 sensors? Ask me about the new ADV retro kits!

    Do you just disconnect them? and how do you disable the signal wire fault in the flash?
