Besides the parameter trigger points stored in logs like boost and torque the ECU stores a date stamp and a type of a dealer code. I have stated this from day one. A big concern would be if there was a emissions non voluntary software update.
Curious then....how long does it keep this stuff for, do you know George? and is the JB1 virtually immune to any type of ECU digging, etc? I only say because there has got to be some values that the ECU is going to see are out of range. I.E. injector pulse/fuel used.
