Title: Trouble getting into bootmode? (me7.1 f29400bb) Post by: cyril279 on February 01, 2013, 09:44:53 PM I have a junkyard me7.1 f29400bb on an 11.6V ATX powered bench harness, and I couldn’t get it into bootmode to save my life.
My harness was originally wired to match this schematic (http://wiki.obdtuning.com/?title=Bild:AudiPorscheSeatSkodaVAGME7.jpg) (I also grounded pin one, and did not use any resistors). Kwp protocols worked fine, but I couldn’t get the ecu into bootmode to save my life. Not with two seconds or six, not with nefmoto or galletto or me7_95040. I found remarkable success after adding a switch to pin 3 at the ecu. Now I can avoid cycling the whole power system. The harness and cable are always energized by the power supply, and I use the pin 3 switch to engage bootmode and power cycle the ECU. fast easy bootmode everytime now, I hope this helps someone else. sick amounts of bench harness info at this german wiki (http://wiki.obdtuning.com/?title=Debugger-Instruktion#ME_7) and of course much credit to the stickied bench thread (http://nefariousmotorsports.com/forum/index.php?topic=417.0title=) thanks ddillenger (http://nefariousmotorsports.com/forum/index.php?action=profile;u=4744) -Cyril Title: Re: Trouble getting into bootmode? (me7.1 f29400bb) Post by: 1gcrazy on June 07, 2016, 11:56:46 AM I know it seems redundant but could you add a schematic of this? I've got an ECU similar to this and I can't get it into boot mode... I've tried 50 times, 20 different ways.

I recommend using 12.5volts to 13.v |
