I have a 2017 zl1 that we want to tune with my auto cal. The auto cal was used for my duramax and has been unlocked from previous tuner and licensed by new tuner. It gives my the 0552 code as it should when I try and read. I then hook to computer and go to tunef3 tab then to the f8 authorization tab and click. The only thing that is there is the info from my e35 controller from my duramax. I have tried 20 times and I can not get that in authorized code to go into the f8 page so I can send that info to my tuner. I even get a message when I am in pass thru mode that the auto cal has sent the info to the f8 page. Is the e35 info in there messing me up?
