Title: Unable to read contents of R32 ECU 022 906 032 CP Post by: G60Dub on October 17, 2013, 11:58:50 AM Okay bear with me as I am at my wits end with this.
I have the 40MHz version of ME7.1.1 and for the life of me I cannot get it into boot mode nor read off the contents using NefMOTO or the English version of Galetto posted on this forum. I have made up a bench harness which will happily connect in Nefmoto and read the ECU data but I cannot get it to read the flash nor connect in boot mode. Incidentally I can read out fault codes in VCDS when using the same bench harness. As fas as I am aware the ECU is standard. I have removed the 0 Ohm link on the underneath of the board as shown here: http://wiki.obdtuning.com/?title=Bild:VAG_ME_711_platine2.jpg and my harness is exactly the 'Hybrid' item as shown here with a push to break onto pin 3 to simulate an ignition switch : http://wiki.obdtuning.com/?title=Bild:AudiPorscheSeatSkodaVAGME7.jpg My harness proves out and there are no errors in the harness 'circuit' I am now extremely frustrated as I have two ECUs to pull the data off as a friend (who lives 600 miles away) has agreed to make some mods for me. Anything else I can check? What memory layout do I use in Nefmoto and what ECU type do I use in Galetto as I'm fed up cycling the retrying.

Title: Re: Unable to read contents of R32 ECU 022 906 032 CP Post by: G60Dub on October 17, 2013, 12:25:14 PM My board is different to the above - Under where it states the boot pin is I have unpopulated 4x twin pad and 2x tri pads and in the area immediately to the right I have two transistor type devices and 6 populated with resistors/caps as such:

16 bucks and works every time.

Not FTDI based at a guess then :) and can I use it to pull the contents of a modified flash? ??? Title: Re: Unable to read contents of R32 ECU 022 906 032 CP Post by: ddillenger on October 17, 2013, 02:16:54 PM It uses it's own program.
As for pulling a modified flash, I can't comment on that. Title: Re: Unable to read contents of R32 ECU 022 906 032 CP Post by: G60Dub on October 18, 2013, 12:08:31 PM Success ;D
Turns out I had actually made an error with the harness. I had assumed that pin 3 was the only ignition switched live and pins 21 and 62 were perm live. So as a last ditch attempt I put a toggle switch upstream of my nice push-to-break 'ignition switch' house in the ME7 connector in short switchng all 3... first try... pulled the binary off ;D Thanks chaps Title: Re: Unable to read contents of R32 ECU 022 906 032 CP Post by: Brumbassen on October 25, 2013, 01:39:08 PM Success ;D Turns out I had actually made an error with the harness.
