PCV and auto tune question

After installing a PCV and auto tune with wide band sensors, do you need to first download a map that is close to your setup or will the auto tune make enough adjustments to get the fuel mix right?

If so, after how long or many restarts?

The short answer is no. I have actually 0 mapped and set the afr's for the autotune, make sure autotune is enabled, and accept trims. First on short rides then on longer ones. I did increase my ability to adjust in configure to 50 from 20. This is a little more work but my 113 has never been on a dyno and runs great. The map is pretty much dead on now and fuel trims in autotune are single digit. But this does take some time. It is not how many restarts but really how many miles.

The advantage to having a base map that is close to your set-up is the amount of riding needed to get the tune where it needs to be. As mitchdm pointed out it is not an absolute necessity but greatly reduces the amount of tuning required.
