I am new to all of this and have dug into the me7.1.1 platform. I'm in the states and have a 2.5L VW Jetta. I bought a ktag box/cable and have already accomplished getting into boot mode and extracting the 3 files. So I feel like I've done pretty good. I have extensive automotive electronic background +solder skills, but don't know what I'm doing when it comes to tuning...

My main question is, if I buy a used ecu that is already tuned by a pretty big tuning company:

A. If I try to immo defeat the already tuned ECU are there any chances I can screw something up. Also I'm curious if I send it off somewhere could THEY screw it up.

B. I have an automatic and the ECU is for manual. Can I copy the map file to my ecu and it just work?

C. What's stopping someone from taking and tuned ecu and putting it into boot mode and copying the tune for a friend or whoever/making a backup of the ECU for yourself? Are there security measures setup to stop people from doing that?

Thanks for the help. I appreciate any feedback.

awesome thank you for the quick reply. So i am working with the me7check and using the files created from ktag. Im assuming this is only able to check the maps file from ktag and not the eprom file? Ktag outputs 4 files .bin .epr .fls and one more file that doesnt have an extension. Im checking the fls file (what im assuming is the map file) and I keep getting this

me7check isn't for eeprom, its for the flash, and you should really be using me7sum instead (which also won't do ST10 images, unfortunately)
