Recently we've talked about getting a P1681 fault accompanied by a no-start condition after reading/writing certain files: http://nefariousmotorsports.com/forum/index.php?topic=981.0Here's the fix. Open your file in a hex editor and find the follwing string: "DB 00 28 02 84 00 ?? ?? C2 F4 ?? ?? 66 F4 80 00 2D" After finding this, change the last byte from 2D to 0D Example: Before: F4 80 00 2D 0D E6 F4 F0 A5 After: F4 80 00 0D 0D E6 F4 F0 A5 Thanks ddillinger for this cool feature!  As always, make sure to correct checksums before flashing. |

A ton of ram logging went into this. Anyone that can use a hex editor can now tune THEIR software without being relegated to switching versions Mazer did beastwork here. Thanks go to him  |

Which versions of ME7 are affected?
I think all ME7 seems to have this, ME7.5 and ME7.1.1 too. |

When you're doing multiple revisions, that can get more than a little tedious. With this, flash one and done. |

I could probably write a little patcher into visual logger when I get a chance. I have two vehicles that this affects, so good deal for me. So what does this byte that we are changing mean? |

7.1.1 Code doesn't exist in ME7.1 If you don't have a car newer than 03, just ignore this entirely |

Yes, the original string with all of the ??'s ensures maximum discrimination against false positives, as well as allows for the best possible compatibility.

I'd say unless you have a SINGLE match, DO NOT MAKE THE CHANGE

If you search for the pattern given, you will find ONE match (and only in binaries that have this code, check the DTC table to confirm). This pattern was derived running it against dozens of binaries, it's as refined as is possible. |
