THKS Sorry I may have exaggerated the number of authen codes I did buy that did not work ---- Actually there were only 3 of them. However I do have 9 2019's that I tried to read and could not get the auto detect to work so I did not buy new codes for those as I suspected there was a problem
So just to clarify ---IF the auto detect does not pull up an E92 then that ECM is not supported ???

PS I have been a Pro tuner for 15 years now and I am not going to quibble over getting a refund on the 3 authen . codes that didn't work
