PCV and Autotune SetUp Question
I know that there are many threads talking about this subject, but they are kind of "old" due to the newer version of software, so I think I would start this new topic.
First of, I've just added an autotune to the PCV, and after downloaded the lastest PCV software, the current map that'c come from Dyno tune is not shown on the screen anymore (it does show on the older version).
How can I bring it back, so I can compare with the autotune table?
Secondly, if I change the AFR in the autotune, and after I "accept" the trims, do I need to "clear trim", to start again, or just keep everything the same, keep riding and "accept trims" as many times as possible?
I hope I explain myself good enough!
Thanks for any help.

To answer your first question, when you hook the PCV up to your computer, click on the "get map" button and the map currently installed will show up on your screen. The map filename may not show up, rather it will show up as "device map", but it is the same thing. This is the original map from your dynotune (provided you haven't changed it). Save a copy of that map before accepting any trims.
Once you accept any trims you will no longer have access to your original map unless you can find it in a back-up file somewhere.
Once you have saved the original map then you can proceed to accepting trims, which will alter the original map. There is no need to "clear trims" after "accepting trims" because accepting the trims automatically clears them as they are hardwired into the base map.
At this point I have to ask another question though - Why would you install an autotune on a bike that was dynoed, or conversely, why would you dynotune a bike that you were going to re-tune with an autotune in the first place? Adding the autotune and subsequently altering the map that was developed on the dyno completely negates the dynotune. Kinda makes the dynotune and the money spent on it completely irrelevant and wasted.

Thanks for the info!
I haven't "accept trims" at all, so I wonder why the original map disappear after I installed the newer version of PCV software.
This brings up a question, if I turn the "hard switch" to "off", will i should be able to switch to another map, which is the original map? How it works here?
About adding the autotune, I have the Dyno done after I installed the new cam (TW6-6), and I like to know what the new HP and Torque will be.
But then, I realize that the mileage is low, and I travel long every year;my trips are always through many different regions, so I think adding the autotune will give me some different choices (maps) when I need them.

2black1s raises an excellent point...if you just wanted to know the HP and torque numbers you could have just gotten a baseline run on the dyno and not paid for a full custom map, which will be out the window the minute you let the autotune start tweeking. Plus who says those numbers will be the same after the adjusted map(s) take over? Maybe its me, but I don't get it

As you may know that there is a feature call "hard switch", so I can turn the autotune mode to "off", and run the dynoed map.
Even tho, I am still learning, but I think the autotune is doing more than just create a "good map" for your bike. Beside, the maps that created by Dyno, or Autotune at your local region, may not be the best, or suitable to another region that may have different temperature, humidity, altitude, etc...
I may be wrong, but so far that what I was told by the dealer technician.
