Hi @
Sportsguy83 ,, I believe the rom is 100% stock tune wise but their is some embedded liience info in an unused part the rom that thue euteck sotware wants to see to veriy your ecutek liience.
if the dealer flashes you a rom update at service this info is lost and you have to contact ecutek or your tuner to reissue your licience
this leftover liience info also upsets the oft autotune generation process as the rom checksum is diferent.
A few minutes with a hex editor comparator and you can tell if a car has had ecutek tune with stock ecutek rom writtem, i believe the additional info is only written to ecu when you lash so you compare the stock ecutek rom before a flash its no diferent but if you pull a stock ecutek rom with tactrix\eculash you an pick out the licience info in the unused area usually padded with FF or OO hex characters
pulling you stock ecutek rom with ecuflash and then rewriting it after dealer flash with ecuflash may be a way of renewing you ecutek liciene which is individually coded to each car
