Basically I have a harness that plugs into that pigtail, and has a switch on the other side. When I close the circuit, I key on, wait 3 seconds, then open the circuit. BAM! boot mode!
And then? Are you able to read the flash using Tony's software? Nik |

I will hold my breath for the version of your software that will be able to read already tuned ECUs then, ha :S

Really, the only reason to read your existing flash is to re-flash it if you are unsuccessful at tuning it yourself. It's worth spending the $20 on a Galletto 1260 cable for that purpose. It's also important to have one in case there is an issue with a flash operation failing (due to a voltage drop, etc) and your ECU turns into a brick. You will need boot mode to recover from this.
Additionally, most tuners move/encrypt/obfuscate maps and inject additional code for map switching which will require more time and knowledge to reverse-engineer than simply starting with a stock file will require. And even if you are able to understand what they've done, you'll probably be appalled at how terrible they are at what they do, and will end up starting over anyway.

I started modifying a tune from a professional tuner. I gave up and retuned everything myself because it was so bad. This was from a large well respected Audi S4 tuner in the US.
The NefMoto flashing software should be able to recover from almost all programming errors. But if something goes horribly wrong, you will need to use a tool that supports boot mode to fix it. No one has reported a case of this happening though.

doh... I had an issue last weekend with the flash bombing out and I couldn't re-flash or read the ECU, so that's when I installed the boot mode mod... If I had known that I'd have dumped the flash so you could look at it.

If that happens again, please send me the log file.  |

Don't feel bad... I ordered mine from what I thought was Texas... 2 weeks later it showed up from Mexico. Apparently e-bay doesn't check what the sender puts in the actual location field. |

As said using boot mode to make the initial 'read' and then write back in.
Open the tuned file read out of bootmode into HEX, search for the NOREAD parameters and change to 00 or FF. Then you can read and write using the NEFMOTO.

That won't work. The NOREAD ASCII strings visible in HEX only affect loading the file in WinOLS. |

I'm not thinking straight apologies.
Search for 8bit 009 010 011 012 015 013 and change 015 to 000 to protect the file, and vice versa to unprotect file.

Yup, that should work to allow reading over the OBD port. This of course assumes that all ME7 ECUs have the same layout of KWP2000 message handling functions in their function table.
