Anytime
So, you've had two jeeps with that same problem right? I have used that particular tune a time or two, with no such problem. I'm thinking that your copy is corrupted. I would try getting a new copy from the diy thread and try that. If you still have the problem. I would get yet another copy, with a different mpps cable and software. Or, better yet, if the file isn't corrupt, the there's, however unlikely:
Use a different:
-The mpps cable (bad ones reported on lostjeeps)
-Copy of the 808 tune
-computer (if available, or a really cheap laptop from a used place)
-And let's not forget the mpps program. Try downloading from a different source if possible.
-you should be able to avoid the Yeti route if you have this on 2 seperate jeeps, as this is the first report of this problem (I believe).
Something is causing you to "lose" a 1 or zero in the file...
Unless its hexadecimal code, whatever lol
