fried my ECM: HELP!!

Well I pulled a good one , I am new to tuning and fried my ecm. Swapped a 6.0 4l80e into my CCSB had hptuners support do the segment swap for the tranny. I decided I would copy and paste the remaining files from the donor file. read the warning about the desired throttle area soo I decided not to copy this I went back and changed the area back to stock or so I thought...hopped in the truck rewrite calibration and truck goes apeshit, reduced engine power ect pegs and now it wont start or even click for that matter. I guess I will visit the junk yard for a new computer, should I get one out of a 2005 half ton or can I get one out of a 2005 2500 so I wont have to do the segment swap again. I have a lot to learn about tuning, a little more to it than turning wrenches

Isn't a 'write entire' required for a segment swap?

Ok. I've never done one, didn't know. Probably wouldn't hurt to try it at this point, though.

Care to elaborate on how this works? I had to do a minor wiring change to get the trans to work with my harnessand anything to simplify this swap would be a big help.

+1 on the 4L60E segment to drive the 4L80E, need minor wiring change as said above.

The F-car 4L60E segment keeps the TCC applied on closed throttle decel (until vss drops below the TCC release curve).
