Any idea what the latest pcm module update is?

Hi all,

I just drove my truck and got a message on the center screen about a pcm update relating to on board diagnostics downloading. Says it improves on board diagnostics to help my engine perform to specifications, whatever that means. Anybody know what this one is about?

Saw that as well, I will hold off on that for now I think until I hear some details.

Well, mine has it now I guess. I went ahead and let it download it.

Let us know if your butt dyno notices a huge increase in power due to "engine performance" lol

I didn't notice much difference at all, but only driven it once since it updated.

Mine had the same update last night as well.

Mine did too.
I noticed some gauge graphics changes within the LCD Dash screen i.e. a line indicating speed control setting on the speedometer.

Mine is supposed to update tonight. We shall see. I'd really like a few minor engine tweaks. Including a more steady throttle response (no surging) and the auto-stop feature to be configurable in settings.
