    Minor correction, the vehicle could be as early as a 2007ish depending on model. The NNBS GM trucks started can-bus in that 2007.5 year, anything else running a E67 or E38 from an early corvette or something would be the same as well.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    I use the obd2 aem and it has been amazing. It was a great starter for introducing someone like me as it is super user friendly and works great with the vcm scanner

    I thought the 0334 worked with any GM that needs the CANDi module, and that's a whole bunch of stuff, but not everything, starting in 2005ish?

    This is great info for me too as I am installing my LS into my car now and it is running an E38 ECM.

    I have a follow up question to this. Would you still run narrow band O2 sensors and the wide band sensor(s)? Or would you replace the narrow band sensors with the wide band sensor(s)?

    I am asking because I am finishing up the wiring and have headers with the O2 bungs installed already. I was thinking that I would use these for the stock type narrow band sensors and add a new bung in both banks just after the headers in the collectors for the wide band sensors.

    Learning a ton and looking forward to tuning with the HP Tuner Pro.

    Cheers, Brew

    wideband is for tuning purposes, not for replacement of narrow bands

    Thanks mbray. Does that mean you completely remove them and plug the bung when not tuning?

    You can leave the WBs in all the time, BUT, they must be powered up and operating. Running the engine with the sensor installed and the gauge/controller switched off will kill the sensor right quick like.
