i have a customer who've done a custom tune by me couple of months ago

then he installed full exhaust and want another custom tune


the problem here is when i plug it to the laptop and oped the DS the message above appears, even when i plug it back to the car in order to return original backup.

the car is Dodge Charger R/T 2014

the version of trinity is 1r13c for DCX

the part number is 6QKLZBD-4

try erasing the custom tune off the tool through the options menu.

i did and worked perfect

until i retune the car another issue comes

"unable to write 1024 bytes"

not kidding i tried to retune 3 times

here are the files


what i do initially is to adjust fuel on 93 Pref tune, i discovered that Trinity wouldn't accept any adjusted files especially with this particular car !!

Facing the same problem

export a new backup to replace the one you have and iit should resolve the issue.
