Quick history, my first tuner quit working after I installed the 93 oct tune. Sent it back to vendor for exchange while married to my car. Downloaded a updated stock tune from your website, got the new tuner to load my custom tune from vendor. A few weeks later my car failed inspection due to 02 monitor not ready. Put about 100 miles on it and still no go, went back to stock tune and 400 miles later still 02 monitor not ready. No cel and my scan tool has no pending codes. After researching obd II monitors the 02 monitor should go into ready state the first drive after it goes into closed loop. I disconnected the battery and after two drives all monitors ran except for the 02. I did live data with my scan toll while driving and all four 02 sensors seem to be working properly. When I reinstalled the stock tune it took several tries it did not want to load for some reason. Is it possible the stock tune I got from you guys has a bug? Passed inspection last year with the original factory tune. Any ideas I'm driving around with expired tag...

post a copy of the backup file please.

Here is the requested backup file in the only format I could send it in. I hope that helps.

there is nothing out of place there, its 100% stock, so I cant see it being a tune related issue.
