when i last spoke with cobb tech support they would not confirm for me that they had not only cracked the ECU but had been able to stick a reflash on it that actually held. not to mention the release date has been pushed back more often than not, as well as the MS6 system all but officially having been canned.
as i've said a million, well more like a zillion times, if and when they make it viable i'll support it 110%. mazda ECUs have been notoriously difficult to crack and to reflash and actually make the program stick by anything outside of dealer WDS systems. many companies arguably more experienced than Cobb have tried and failed, so between that bit of history and the lack of real enthusiasm on thier part since - even by your own posts above - April, you'll have to understand my skepticism.
this doesn't even address the possible shortcomings of ECU reflashes which have already been covered here and other places many times before.
