Dealer Computer Reflash

I have been reading several threads discussing computer reflashing by dealers. I was wondering why these computers are being reflashed and how do you know if your vehicle needs this? I have an '06 and was wondering if my truck need/benefit from this?

You would do a dealer re-flash (primarily) for 2 reasons I can think of:

1) There is a factory service bulletin on the ECM that would fix some problem you have or is required by Dodge as a preventative measure. The dealers will flash your ECM a lot of times when you take the truck in for something completely unrelated; it's how they keep the ECM's current and protect themselves from warranty expense for known problems.

2) You bought your truck used and have no idea what the ECM really has on it.

2)

My truck got flashed once from a 20 year old blonde on the interstate. It really improved my driving experience!

If your truck is having hard cold starts, missing, excessive injector knock, or other drivability issues, then an updated ECM flash (reprogram) might help. If it is running fine (no white smoke) I'd say leave it alone.

I don't mean to hi-jack the thread but is "reflashing" what the dealer does when they reprogram the tire size?

I work at a dodge dealer and the info they have already put is correct. If there is a service bulletin that is related to a problem you are having then the tech will flash the controle module if the service bulletin says to do so and sometimes they will send out a recall and have all the vehicles flashed due to something that has effected that paticular type of vehicle and they are having problems with it.

As the tech told me the last time I had it in to clear a CEL that I caused, he told me that yes they have ECM updates for the truck but if your not having any problems its best to leave it alone and not update it. I've read a few post about those who got a reflash done just because they were told it would make them get a better running engine or some other BS. Well some lost mileage and some had problems with power loss so don't get a reflash done just because you want it as you can never tell what can happen to a truck that doesn't need one.
