I just got my dually out of the dealership and they charged me $98 for the latest flash.

What does the latest flash do for me?

 

i think it was mostly aimed at cold start isues, such as missing and white smoke.when i got mine flashed i didnt notice anything except a little less power, but ive never had starting issues with mine.

 

Jim it says you have an 06, why would they charge you for a flash? are you over 100k? im just curious.

 

Yep. it has 120K miles.

 

The latest flash preheats the injectors thru induction to eliminate stiction which causes cold start issues and after X amount of idling it exercises the variable turbo and idle rpm's. After about 3 to 4 min. of idle I can hear the rpm's change. I have not noticed any diff. in power and no change in mpg's.

Worthwhile to get this flash on an 04 manual transmission?

 

I would, even if you didn't live in a cold climate the latest flash will exercise the turbo vanes, helping to prevent them from sticking.

 

I bought my truck used, is there a way to till if you have the latest flash?

 

I'm with Miguy....how can you dtermine latest flash?

 

I saw in an earlier post that there is supposed to be a sticker with the latest flash recorded on it somewhere under the hood. I can't find one anywhere on mine.

 

Knowing that mine was just re-flashed, I just now looked for a sticker and could not find one anywhere.

 

Same question about how you know which flash has been performed...the diesel tech here told me they reflash with the latest one on every PSD that comes through no matter what it is in for. Sound right?

 

Yep same here no sticker

 

The easiest way to find out if you have this flash is to let your truck idle for a couple minutes when its at opperating temp.The turbo will whistle for about 10 seconds then a slight rumble with a less pronounced whistle for 10ish seconds then rumble like a big block for about the same amount of time.Then start all over again.
