blackbear said they can work with it as it is so no biggie really I guess, previously they said it had to be stock.

You said BCM before, I wasn’t aware you were talking about BB flashing the ECU or TCM. Yeah they can be flashed with an Autocal as long as they aren’t bricked. BB doesnt flash BCM’s. I used the Autocal to flash my BCM with BT Dieselworks custom tune for it and same thing- it doesn’t look for software versions unlike the Tech2, AFAIK. It can get confusing to me. Now I was just wondering- I’m pretty sure I can’t use the Tech2 to flash my BCM back to stock since it has a custom tune on it. Not that I would want to anyway.

Meh,
I ordered the rod bearings, ARP engine mount bolts since i lost one of the factory ones.
and a set of plugs.
I figure it's probably not a bad idea to change the plugs after engine break-in.

From all I've heard this is correct. Pretty sure we can't use a programmed BCM from another truck to reprogram to ours; the remans come with the VIN cleared, I think, ready to be flashed.

ya I thought about looking into going backwards on it but it's not worth the hassle at this point I just setup the autocal with the configuration for the nnbs to take a log file, I was little afraid to erase it because it has my 2018 files on it but they are saved in a folder and switching it back & forth just takes a couple clicks.

Uh huh. I flashed my BCM with the Tech2 but it did no good for what I was trying to do- fix an SRS issue.
