How would I go about going back to a stock tune from a Trifecta tune? I know I need to rent the cable; however,

A) where do I rent/buy a cable

B) wher do I get the stock file for my car


(Bought the car with the tune, want to go HP-Tuned)

EDIT: I now realize I probably should have posted this in the Tuning section. Sorry Mods. Move if required.

Well u can buy the cable from trifecta. Or borrow from someone. U need ur original tune file to flash it back to stock, if u know the previous owner, or contact trifecta see if they have it. The stock tune file is built into the tune file that is flashed into ur car

or you can force the stock file over the trifecta **** and go about your day.

I have the Trifecta cable cord for sale if you're interested.

What if the original owner does not have the stock file?

Go to GM and have them flash a stock tune.

Adecker

Thats a good idea; however, would getting a PCM from like ZZP do the same thing? Just retune it immediately?

When you open the Trifecta software (available on their site) there's an option to go back to the factory tune.

Adecker

Oh really?! Sweet. Which website, googled Trifecta but there isn't any hits with a software download.

Found it. Sorry lol

Adecker

Downloaded the software, obviously not hooked up to the car; however, not seeing an option to go back. Do I need to be connected to the car?

You still need the car's Trifecta tune file;
You might be able to request it from WOT - since your car is on their database, they should have no problem emailing you a tune file so that you can go back to stock.

There might be a fee - but it would invariably be less than what a dealer would charge you to put the stock tune for your car back on.

Adecker

Sweet! Got the file! Thanks all for your help! Now I just need HPT

incase i'm interpreting you correct;
now that you have the file, you need a trifecta cable (you cannot use HPT to flash the stock/trifecta file to your car);
then you start up the program to flash your car;
select the trifecta file, then on the following window you select that you are going to flash the stock file.
be sure your laptop has a full battery, and that your car battery is good - needless to say, bad things happen when flashing and the connection is lost.
Same goes with HPT (afaik).
