Default Can you over AutoTune?

Like the title says...can you auto tune too much? Or does the Power Vision auto tune prevent any possibility of "over tuning"?

Thanks,

Robert

according to ken peters from dynojet yes you can auto tune to much and it will effect your tune.

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!
