Hello guys

I have ecuflash tune on my car right now. If I flash a cobb tune, the rom image that cobb save on AP is probably not stock, correct?

do you guys think if it is possible if I do the following to get stock rom back on the car:

- use cobb to flash a good stage2 map
- replace the rom file (ecuflash) that on AP with stock rom.
- un-install cobb. this would restore the stock rom back on the car

possible? what do you guys think? let me know

I guess you're looking for a stock MR ROM so you can flash back to stock? If so you'd need to tell someone your ECU ROM ID.

I don't know why you want to use the Cobb AP to go back to stock tune. I'm probably missing something here.

You'd best get a stock MR ROM for your ECU ID, fire up ECUFLASH then write the stock ROM on and you're done.

I have my stock rom, but the problem is I don't have the tatrix cable. I do have AP laying around.

I want to go back to stock first, then do the cobb tune.

Oh right I understand now. Sorry I have no experience with AP.

Why do you want to use the Cobb tune over the GST tune?

some issue with SST. I want to put cobb back so I can compare.

The Cobb AP includes a stock ROM as well so you can perform the test you're attempting to do, it will just save your current tune as your base and will put that tune back on your car if you ever uninstall the AP.
