Tuner Question For 2016 5.7 Hemi

[cubmedic]

So If I install the ECM and tuner on my Ram and have to take it to the dealership for anything, will they be able to flash the ECM and disable the tune?

If you have a tune installed and take it to the dealer and they do a PCM flash it will put it back to stock.

Will I be able to reinstall the tune?

Depends on the tuner. Your best bet is to put it back to stock before taking it to the dealer.

I'd return the unit to stock before going to the dealer so that the tune or the PCM won't get scrambled.

echo... LOL

But doesn't it lock the PCM if the dealer flashes the PCM. That's why I bought a Diablo PCM so I could switch them out.

No it doesn’t.

I thought that 2015 and up they locked the PCM

The PCMs are locked from the factory in that you need a PCM that has been unlocked by someone like HP or Diablo. Flashing the PCM does not lock it.

OK. I thought the way they told me that anytime the dealership flashes the PCM that it locks it. I must have misunderstood.

all ive ever heard that if the dealer flashes it it relocks it. if you buy a seperate pcm then just put the stock one back in and then take it to the dealer

That's what I did I bought one from Diablo and when I take it back to the dealership I swap them out.

Thought the "lock" was a hardware thing that needed to be physically removed vs a software lock

 

[whetrick1]

No its a software lock

How can that be if it can't be unlocked via software? That's why we have to give a pcm

 

[whetrick1]

It can if you have the right stuff. Diablo can unlock them but they will charge you to do it. That's why I change out my pcm before I take it to the dealership.
