The first public release of the NefMoto ME7 ECU Flasher is now available in the forums.

I have almost finished working out all of the issues with the slow init connection mode. I have one more timing issue to handle, where the 2000 ECUs take too long to send the key bytes. Once that is resolved I believe everything will be ready for the first public release.

I has also found that I can flash 2000 S4 ECUs as long as I connect with slow init. When connecting with fast init, the 2000 ECU get stuck in an infiinte loop when trying to start the programming session.

So currently I have tested and support flashing of 2000/2001/2002 S4 ECUs. I believe my software will have no problems with any 2.7T ECU though.

Hopefully I will be able to release in the next few days.

I have succeeded in getting exact timing in the ECU KWP2000 connection code for fast init. I ended up using the bit bang methods in the FTDI D2XX driver to accomplish the exact timings. Logic analyzers are a great tool.

Problem is, I still can’t connect to the 2002 Audi S4 ECU. So I decided to contact some people who write professional VAG diagnostic tools. They confirmed my suspicion that KWP2000 fast init is not properly supported on all VAG ECUs. Their recommendation was to use the slow init method instead.

Alright, now I know what the problem is, and with my mad bit banging FTDI skills, I hope get the slow init method done pronto!
