Hi,
Was thinking about buying one of these dohickies. Don't know what the hell I'm doing. Started researching.
First question I have is. Does the e38 ecu have to be unlocked to use this?
The 2nd question is that if the ecu is unlocked, and you flash back to factory tune. Will the Cal Id-s and CVN's all match factory?
Need info.
Make it so!
