Anyone loose their computer? 2013 XLT with 22K miles wouldn't do anything except flash a lot of things on the dash screen and of course not start or even turn over. Went to he purchasing dealership on the hook to be investigated... They and said the computer was toast and will be replaced under warrentee. Only warning was the the throttle (by wire) would not respond once last week. I had an Edge CTS plugged in and used as a monitor only; never loaded or tried to load any performance or mileage upgrade, I removed it before sending to the dealer just in case. No mention of any was asked or said.

Anyone else ever have this?......JD

 

I have seen shorted' bad batteries scramble puters ... Have the dealer check all aspects of your issue .
Could have been a bad unit . Ask them to verify the cause of the failure .

 

PCM has been replaced. Could not determine what was the problem at least to me.
New question. Transmission now shifts earlier than before and will go into 6th gear at 40 mph when driven easy in town. Never went in before 60/65 on freeway and never in town. Do they sense load? It is a max-tow with 3.73 gears if that makes any difference. In tow mode seems normal but I haven't towed yet. Should they have had to program it or at least check the program after installation? How about 2014's and 2015's do they shift earlier and spend more time in 6th for milage? Thanks
PS: where is it located?

 

It should learn your driving habits and adjust accordingly over a few days. Same as disconnecting your battery.

 

OK not complaining on early shift or 6th...may help mileage. New thing. I always had a monitor plugged into the OB connector to see some things the dash didn't have; all still work withe exception of the Boost which I really liked. Any ideas on a way to check that out with a fuse or something?.. Thanks

 

Found it... Selected MAP sensor for the intake manifold pressure and it can up on my screen.....
