Yet another flash question (taking data off the ECU/saving)...

[turbolarry]

So my cable got here yesterday, software is on the laptop, I think I'm ready to go.
Plug it all together, power the ECU, turn on the laptop, open ECUflash and;
Click "Read from ECU" right? That will be my stock map? As far as I know I have to save that somewhere safe and warm but;
Should I make a copy and work off of that, just change the file name?
Can I click "Read from ECU" again and have another working copy?
I can "Read from ECU" and still have a running car while I work on the maps right? It doesn't blank out the ECU anything right?
It's the "Internal ID" that is important not to change and be careful with? Anything else to watch out for regarding file coping/saving? Oh yea the immoblizer too huh?

Nothing happens to the ECU until you upload another map. Once you do that, to return to stock, you need to upload your original stock map. Read the first time and name it "stock" or something, then make a copy and start tuning with it. Each time you make changes, you will upload your tuned map again and go log until you get it right. At the end, you'll have a stock map and a tuned map. You can then make as many different maps as you want.
