But I thought 1 hr was pretty good, though I don't know how long it takes to load, recode and write back to the car. Was under the impression it was a fairly slow process...
If it goes smoothly it is well under an hour. Should be less than half an hour. But things don't always go smoothly.

Probably a dumb question but...if you code for a new battery, will it overwrite your DME if you have a COBB tune?

No it will not

I have a cobb tune, its basically a parameter change and not a flash

Its basically changing an option in your computer, best way I can describe it
