A new update came out, not sure if it was this week, last week, or the week before BUT i know one of the items in the PCM (or whatever dodge calls it PC brain) fixed the OAT sensor calibration.

Does anyone know what ele that update did??

 

No, but I will take mine in soon for all of the fixes. I was waiting for a few to come out before I took it in.

 

Slightly off-topic but where do I look to find when updates come out?

 

I'm just going to wait until I need my first oil change, then I'll take it to the dealer and let them fix everything.

 

i was told that a new harness is what fixes the temp sensor problem. i had mine replaced on wednsday afternoon and now my temp is reading correct.

 

can someone plese tell me more about these updates? never heard of them.

are they performed automatically when you get your truck serviced, or do you have to specifically ask for them??

 

Just a word of caution on these reflashes to the PCM. Back when I purchased the first model year of the electronically injected Cummins diesel from Dodge, we would typically receive notices of "upgrades" that were available from Dodge in our snail mail at home. I don't know how the upgrades are announced now. All of these upgrades promised to "fix" something, or improve performance somehow. I took my truck in for a reflash of the PCM, and the truck ran WORSE afterwards, with noticeably less power, but also with noticeably less diesel smoke on cold mornings before the engine warmed up. Later, it came out on the diesel forum that the reflash I had taken my truck in for was in reality a reflash to make the truck more emissions compliant, and it actually decreased performance, just as I had thought from my seat of the pants impression. Since that time I have been more cautious about letting a dealer (or Dodge for that matter) reflash my vehicle. My current Hemi Laramie runs FANTASTIC, and as long as it keeps doing that it isn't going to be reflashed.

Thanks for the great information. No way they're going to rob me of more power

 

Just like MOPWR2U said, I came from a Ford F-250 with the 6.0 Powerstroke and it was one of the first years for the engine. Ford had some serious EGR valve issues with the engine and I was constantly going in for PCM updates. Every time I went in for an update, they may fix one thing but took away a couple other things like power and some other nice features. The biggest thing (with Ford at least) is that once they reflash your PCM, if you don't like the new update you are stuck with it and can't go backwards. It may be possible but I doubt you will find a dealer or tech that would either know how or be willing to do it.

 

same w/ chrylser, no backwards flashing. only way possible is to get a new module, and hope someone somewhere has an flash file saved. other than that, SOL.
