The OEM ecu will try and run rich if it doesn't come up to temp. And the 180F t-stat will affect this on a stock ecu tune.
Been running mine for 4 or 5 years now with no issues. Some people in the colder climates have set off codes which can be easily cleared but it can be annoying . I would recommend changing them out for the summer months if you are located in that type of climate it is not a big deal to do so. The 180 running temp is still within the proper parameters and the car will not run rich as has been rumored .
is there a sticky on this, are we talking 30mins, 2hours?
I am not sure about a sticky but it is in the Bentley manual. I would guess about a hr for the first timer and much less after that . As I recall the housing itself is only 3 bolts but you have to move a few things to get to it . As I said in my previous post it was four or five years ago and my memory isn't what it used to be I did find this link to a thread here with quite a bit of info.
