I would guess its another update to the base OS that Dodge has released. This is pretty normal for Smarty to do, about twice a year, to keep the software synched to where it will load correctly.
The downside is you don't know what other effects, adverse or not, it will have on the truck. Kinda like getting a flash from the dealer to fix one problem and it changes something else.
Hence, I have not updated my Smarty software for over 2 years. Don't want to screw up a good thing. :-laf
Check out the "news" on the madds website. It said part of the s06 update is better timing.
There's another update today! High idle this time.....
How do you enable high idle on an '03 CR??
