Mail order tune - "Saved data"? When you send in a your pcm for a mail-order-tune, is the tuner able to pull any data from the pcm about how the car is running?
For example, can they see what your air/fuel ratio has been and what your timing is, etc?
I'm not sure if any of this info is "saved" to your pcm or if the tuner is just applying a general tune without any data about how the car is runing?

They will have the ability to see your entire tune. So yes they could see your spark tables and your commanded AFR. At WOT your pcm ignores the o2's so it has no way of knowing if the engine is going rich or lean. The tuner wont be able to see if you have been getting knock for whatever reason and they will probably just take your pcm and flash it with their own "mail order tune." Or maybe they will just alter your original tune im not sure. Seems a little redundant to save everyone's original tune.

As for the last sentence, I guess that depends on your tuner.

yes, they can see how your current tune is set up and what things are set to... but they won't know how well the car is actually running with those settings, unless you provide them with recorded data logs so that they can see data from several different parameters...
