Its very exciting, and you seem to have an excellent grasp of whats involved, and also a keen ability to share it clearly with the readership... Good job, Shiv!!
From what I understand...(shiv correct me if i am wrong..) the difference is that the XEDE doesn't necessarily reprogram the ECU per se...it intercepts, and modifies, the data coming into the ECU from the engines sensors.
