Having an issue with last tune written. I have a intune i1000 diablosport. I purchased a custom tune. I loaded the custom tune into vehicle. When i try sending the last tune written file to Lewis it only shows the canned diablo tune. i have deleted the custom tune then reloaded it to the tool but same problem keeps happening.

Seems like or NEW tune is not loading into your ECM
When you load it does the screen say that it is finished or done ? or something like that ?
Make sure that you turn off all the accessories in your car--lights A/C radio etc--
Make sure your battery has at least 12 volts
Make sure your cigarette lighter fuse is GOOD-----GM hides the fuse to the OBDII port on the cigarette lighter circuit--

When you load your custom tune into the Tunes directory in the File directory, you should get a confirmation on the Intune a few seconds later saying "Custom" tuned loaded.
When you flash the vehicle with the custom tune, the Custom tune will automatically be saved as "Last Tune Written" in the File Directory.
If it keeps showing the canned tune when you send the file, then maybe the tuner by accident saved the canned tune over the custom tune. We're all human.
