Morning gentlemen,
Have a question for you.
As I was intending to get a smog the other day, my car battery had died. Got it replaced, but apparently my emission data had been wiped from the system. I was told I would have to drive it around "a bit" before the data could be generated again so I can actually get my smog... but how far is "a bit" exactly? 50 miles? 100 miles? 200 miles?
Thanks.
The fact that they can make you do that is disgusting
10 miles or so.

Do you have any idea how a self adjusting ECU works?

About 10 to 20 miles, however long it takes for the Catalytic converter and O2 sensors to heat up and generate some reliable data.
Just go do some highway cruising.

up and down the highway ~50 miles total is what I have to do with my Mustang (it sits a lot). Most was ~400 on a Cobalt I replaced the fuel line on. Fucker refused to register the evap sensor for a week or two.
Google OBD2 drive cycle. It should tell you how to set the emission monitors quickly.
It can depend on the vehicle what conditions are needed to compete the readiness monitors. The hard ones are EGR and EVAP.
Egr will take some highway cruising, at least 55mph for a few minutes, then a coast to stop (such as an offramp) and stopping in gear for a minute or two.
Evap on the other hand cannot ready itself with a full tank, actually I think it has to be less than half. It will also need to sit overnight to complete this cycle.
Check your local laws as you are usually aloud to have one or two readiness monitor not complete for testing. This is to unsure grandma can still get her inspection even though it takes her a month to burn a half tank of gas and never goes on the highway.
I'm just glad I don't live somewhere with emission testing.
