I have read ALL of the threads on this. I've been following it since Shiv got his 335. I will say that although Shiv has never called it a "piggy back" he has responded to posts calling it that such as this one
and never corrected anyone.
I wouldn't call it a standalone ECU as it does not work all by itself. It works in conjunction with the stock ECU. To me that implies a piggy back type scenario where the Xede is working with stock ECU instead of replacing it like a stand alone ECU would.
Either way, no matter what you call it, it's an awesome piece of work and I plan on getting it sometime in the near future for my 335 that I'll be picking up tomorrow.
