2002 Pontiac Trans Am Original backup not saved

[Luckyzach]

T1000 not saving the stock tune file, 2002 Pontiac Trans Am.

I recently bought a used Trinity T1000 from someone and the unit has been unmarried and is in working order but when I go to mess with tuning it, it goes through this. I can't seem to figure out what to do. I've updated it hoping that might fix it but it didn't. I'm stuck at what to do and really wanting to see the potential the unit has for my car. This is what happens when I click on performance and go to start tuning and tells me I need to backup the original tune.

It says "original backup not saved (-11)"

When I click on more info, it says "PCM: error prepare read (-1)"

And then it proceeds to try again with the same error codes. Any help will be greatly appreciated. My car also has its stock tune so that can't be the issue.

I've seen a previous post similar to mine but with no answer on how to fix it.

key turned to ON position? have anything aftermarket installed, like aftermarket stereo, subs, amps, nav, remote start, heated seats, etc? If so, anything aftermarket like that needs to be disconnected...

So for it to work, I have to disconnect the stereo and subs in my car? Because I had it running when I was messing with the performance aspect of the tuner. Do I just need to turn the stereo and subs off or do I need to disconnect all of it?

you may need to disconnect it for the install.

I'll give it a try as soon as I can, I'll let you guys know if it works or not.

I did that and it worked! Thank you guys very much!
