Can anyone confirm/dispel that the 2006GT ECM is now ‘smarter’ than the 2005GT ECM? I’ve seen some threads stating that starting in 2006, that technology now exists which can tell if you have EVER reflashed your ECM, even if you put the stock factory tune back on. Some posts suggest that Dealers can now tell if the ECM has the original factory flash.. even if you download the original tune stored on your tuner and reflash the ECM just before taking it in for warranty service. Something to do with “# of flashes”. For example, even though you reflash the original factory tune, it will show up on the ECM as “#5” flash instead of “#1” (out of the factory)… and dealer knows what’s up.. any Ford techs out there that can confirm/deny?
