Possible to revert to stock tune if backup not available?

[SQ13]

Hey guys. My E46 came with an Epic tune already flashed in when I bought it. I am getting ready to do a manual swap, and I wanted to go back to the stock software when I do the swap. However, I don’t have a copy of the file. How would I go about obtaining a stock file to flash, if possible? I’m willing to pay someone to help me with this. Thanks.

Just flash it with WinKFP

I haven’t used any of the BMW software in years. Will WinKFP have the correct file need to flash the DME? I don’t want to flash the wrong file or brick the DME.

Should find the original OEM bin here: https://github.com/saildot4k/MSS54-X...mps%20-%20Full

Need to know the version number of the software on your ECU though. The strings in the filenames (e.g. 211322001501JD34) are generally found as a string at the beginning of the bin. Have you tried pulling the bin from your current ECU?

ECUWorx has a list of stock DME tunes for free.

Why not modify your current file to manual? Quite easy to do.

The Epic tune is locked, and I don’t want to keep it anyways.

That’s interesting. Our car came with an Epic tune but it was not locked.

For what it's worth, I'm running Epic on my manual car and I love it. Hard to get much better than Randy's support.

just read your ecu. this file won't be locked and edit the file with ecuworx or tunerpro

Hmm, maybe it isn’t locked. I’ve heard from many people that Epic locks their tunes, so I just assumed mine would be, too. I’ll let the shop thats doing the swap find out for me..

in my experience, MAF tunes are usually unlocked. The alpha-n tunes are generally locked.

Not sure why, this has just been my anecdotal experience.
