I thought it was called a CASE Learn? Where the car basically had to recalibrate itself after a major changing in how its timing and stuff is done. I know I am not using the proper words, but it something a lot cars go through when changes occur that are out of the norm from what the car has learned prior. Hence the "learn" process.
Here is a link I think you might useful in gathering the information you need to do this.
