2012 6.7 flash advice

[Reini]

Hi all

as you guys know, when you cannot read out a 2012 6.7 ecm, you are supplied with a stock file.
as stated by hptuners, you just can flash in the modded file, the patch seems to be applied on the very first upload, no other action is needed (VIN from the truck is transferred to the new file??) ..correct so far?

my question now, if someone sends me over a tune for a 6.7, same year, etc. can i upload this file, or must i change something? if yes, how can this be done?

any answer would be great!

thank you

Hey Reini
I'm a nooby so don't take my answer as set in stone.

Reading through the forum it appears you have to add ALL changes everytime.
The best way to do that is Compare file, you can go tab by tab, table by table and see/change the differences.

I haven't been able to get into my truck yet due to Check sums issues.
I did compare file on my Camaro and it works pretty good, any differences are highlighted.

Take care

yup agreed with above. When i received a tune to try i just went tab by tab and changed it over to my read file. You can not just upload it.
