Question about PCM flash...

I am thinking that I might break down and let the new flash get done to my truck. This being the inductive heating flash for the injectors. One question is this will the pcm flash for the injectors include all previous running changes? The one I am really after is the trans logic change that pertains to the TSB 07-6-9 6.0L DIESEL ENGINE - BUCK/JERK WHEN PULLING LARGE/HEAVY GOOSE NECK TRAILER and want ot make sure if I step up and have the latest flash done it will actually do what I want it to do. Secondly, my dealer knows I have a Edge Platinum, I know they know, they have done warranty work in the past with it hooked up but never a flash. Do I need to unhook it just for the purpose of the flash or will the Edge even make a difference? I wouldn't think so but just want to be sure. Thanks all.

I have the equipment so I do my own PCM/FICM/TCM flashing on Ford vehicles. You will need to disconnect the Edge before flashing. I tried to flash my '03 F350 with an Edge connected and when I tried to do the flash, I kept getting an error when the computer tried to rewrite the PCM or any of the modules. When the Edge was disconnected, the flash would take just fine.

You will just need to unplug the Edge from the PCM and plug in the original OEM wire harness. Any connections to the MAP or EGT pyrometer may remain connected.

Being the owner of an early '03, I would highly recommend the induction heat flash. The buzz flash didn't help much at all. It was just annoying. Even though it only gets down to about 25 deg. F in the winter, it made a huge difference in starting and drivability while the engine is cold. Since I have a manual transmission, I can't comment about the Auto shift patterns or Tow/Haul.
