Default New heads/cam now it doesn't learn

So i just swapped the heads and cam, nothing huge just 243 heads with a TR224 cam
Now it takes the computer about 5 minutes to learn how to idle on top of dying on falling revs, it does it EVERYTIME I start the car. It's not remembering anything.

Auto or M6?

Thats fairly normal especially if A4 , your gonna need a tune to raise that idle and correct your AF ratios

True you need a tune! EFILive or HP Tuners and someone who knows how to use it.

It will never, ever "learn" how to idle with that cam. Any cam beyond stock will require some level of custom tuning for best idle quality. With a cam that sized, idle will never be good unless you tune it.
