I don't know the answer but this related topic may help:
When taking your car for inspection I've been told that if you reset
the ECU, you have to wait 2 weeks in order for the car to be able to
pass inspection by reading the computer. My guess is that's how long
you'll have to wait as well, and I mean wait to check the computer
again while driving the car, not just have it sit there, of course.
Hope this helps
