Can you over AutoTune?

From experience with a car, you have a couple things to be concerned with:
* Eventually the tune will just stop adding any value at all. Changes will be minimal and pointless
* Every time you reset the ECU, you lose any learned values. These are a way for the ECU to adjust to current conditions as well as long term changes. The ECU will re-learn these, but...eh.
* The flash memory your ECU uses has a maximum erase cycle expectancy. Getting anywhere near that number will cost you a new ECU.
Best case scenario, you end up in a feedback loop where a change you make causes the motor to learn a new value. When you flash that new value, it learns the original value...forever. There's a limit to the detail a narrow-band O2 sensor can collect, so you're not really doing anything that great anyway. Getting a professional tune on a dyno would be a much better use of time as long as you choose a reputable tuner with lots of working motors under their belt.
Good luck!
