Hi All,

I have an Autocal that came with a VIN license an delete tune. Another tuner used the Autocal to re-tune my truck, and as he put it used it as a 'pass through' with his laptop. He has since emailed me the tune file which I want to put on the Autocal so I can reflash the truck if needed. Can someone walk me through this please? I have Scan and Tune, and Explorer software on my computer....just want to make sure I do it right. The old tunefile from the original Autocal is still on the unit.

Thanks
