Not to stir the pot and cause any more dissention, but......the instructions that we send with EVERY tuner we sell plainly states to hook a battery charger to the truck BEFORE downloading a tune. The screen on the Dashdaq also communicates the statement "DO NOT TURN THE KEY OFF". Choosing "cancel", pressing the power button on the Dashdaq, turning the key off during a download OR.... NOT having a battery charger connected to the truck can and USUALLY WILL fry the TCM (transmission control module). We also heavily stress this to customers who call in to order one of our tuners. Just because it only takes 15 to 35 minutes to load a tune, a lot of folks think....."oh, I have new batteries" or "oh, my voltage won't drop enough to cause any issues". The possibilites are endless for ways to cause issues when administering tunes to these trucks. Occasionally, we hear of Ford techs who mistakenly diagnose (after a download failure) the PCM to be fried when 99% of the time, it is actually the TCM that gets damaged. We hear stories from day to day that would blow your mind. Wives doing the hubby a favor and turning "Joe's" key switch off (doing him a favor). "My buddy interrupted me while downloading a tune, so out of habit, turned the key off--- got out of the truck and then realized my mistake". Unfortunately, this is not a perfect world; nor are there any perfect people. We are here to help any and all who need our assistance and would prefer a call for advice or help BEFORE you do anything you are not sure of. Your apology is accepted and appreciated.......BUT, please let this be an example of how to use good business practice and forum etiquette, and as my Mom would have said "if you don't have anything good to say, just say nothing at all"! (or at least discuss it in private)
