i am trying to "read" my stock tune for the first time and with the key in the on position & the autocal hooked to the truck all of the "read" options have N/A listed below them and even if i hit the ok button on read 1 nothing happens. I have tried multiple times. What should i do to get it to read the stock tune for the first time?
What am i doing wrong or am i missing something here?
Thanks
