I will try to explain my problem now apologize for my English is not good.
I tried to apply diablo tune + AFE intake in my LT1 C7 2015 without success.
Let's get to what happened ..
I remember that I did READING backup first step successfully but during WRITING process to get close to the end (about 80%) the panel of my car went out (as if off) and saw at Trinity screen that the process failed after that I started getting errors.
so when the trinity stopped try apply the tune and went back to the home screen i tried to turn on the vehicle that did not work.
after a while I tried again and the vehicle turn on normally.
tried again apply the tune however now get an error (-11) for the PCM saving process and sometimes the system reports as if I already had one applied or something tune.

in short, the tune can not save more back up my car and also says not have any backup therefore also can not apply the tune

when tuning the C7 be sure to press and hold the start button for 8-10 seconds to engage RUN mode.

What does the trinity display for options/show last tune written?

When i tried again i the trinity try READ PCM i think and after try a receive the error code (-11)

and thats it on first try i don't hold the the start button for 10 secs =[

try do again, so..

Step 1: READING... PCM...... DONE!
Step 2: waiting 20 seconds..
Step 3: "Original BackupTCM NOT SAVED (-11)"
Step 4: "Trinity will now make a 2nd backup attempt."
Step 5: Please wait
Step 6:"Original BackupTCM NOT SAVED (-11)"
Step 7: "Trinity was unable to save your original tune after 2 attempts. This can happen if the vehicle already has a performance tune"
Step 8: "Not tuning vehicle because of backup (4)"

End =[

You need to make sure the tool is up to date and go to options/change trans type and select manual so it will ignore the 8 speed for now since it is not yet supported.

Thanks

Ok, select manual transmission and follow steps
