Just got a Galletto 1260 and built a bench harness.  I'm using a regulated 13.8V supply
I just can't get it to go into boot mode.  I'm grounding pin 24 on the flash chip exactly as described here:

http://www.audizine.com/forum/showthread.php?269322-Tuning-your-Motronic-ECU-%28ME7.1%29

and I get 'BOOT MODE INACTIVE'
Is there a possibility the pin for the k-line (43?) are different on this box?  I can't find a wiring diagram to confirm.
I know that communication to the cable is working because the light flashes when I try the non-boot mode (Audi VW 2.4,2.7,3.0, V6 /4.2 V8 ME 7.1.1 29F800BB).  But then it just sits and cycles forever

do you have ignition pin as well??Bosch me7.1 and 7.5 are all the same,I built a harness as well,But I havent tested it yet.My pinout for boschy me 7.5 is like this.Pins 1 and 2 are grounds.Doesnt matter if you switch them between each other. Pin 62 is battery power, pin 3 is your 15 power or ignition source, and 43 is your k line. I havent had the chance to test my set up hopefully tomorrow.Let me know if you have any other questions.Im learning this as well.But ive done some extensive readings. I ll try to help you as much as i can.I have spare me7.5 ecu i am using to test.to see if ill be able to read a bosch me7.1 for my car.

Only other thing you can try is the 29f400BB or the other one.

I was able to get it to do 'something' in non-boot mode, so I know my bench harness works now:
BENZINA 
Audi VW 2.4, 2.7, 3.0, V6 / 4.2 V8  ME 7.1.1 AM29F800BB

.22906032C
MOTRONIC ME
0261207881
1037366374

but then I get:
errore Skl
Errore seed key

beware, there's a post on here with a bench diagram that is backwards
pin62 should be constant +12V power source
pin3 is switched ignition power.  I also hooked up pin 21 to switched power

But I still can't get into boot mode.  I checked my flash and it is 's' type which is 44 pin, and that puts the WE* pin at #47.  But all instruction point to grounding pin 24 which is DQ4? (data 4)
I've read that pin 3 of the serial eeprom also works, and that is the write protect pin.

Perhaps some implementations don't have boot mode?

Yeah Sorry.I just looked any my wiring diagram.You are right pin 62 is 30 power aka battery power and pin 3 in 15power of ignition on.I dont think you need pin 21.I havent had the chance to tyest my setup yet .Im not in a hurry but I hope to test it this sunday perhaps.

Ok I successfully Test my harness and It work.However I get a message that tells me to put a short to pin 24 which i do and let go right when i click ok and it read out the ecu numbers.Then when I go to read out the flash i hold the ground to pin 24 during the whole reading process.I have a file from a bosch me7.5 ecu.is it possible the whole file is only 512kb???

which version of galletto do you have???Also I do mine like this.I turn on my power supply which is a regular 12v car battery at this point in time,hook up my bench harness to battery and the other end to obd2 connector for galletto and the respective pins on the ecu.I plug in the usb into my laptop.Then i ground pin 24 and hold in on pin 24 until i turn ignition on which is pin 3 on the ecu.after ignition is on for 2 or 3 seconds i take the ground off from pin 24. start galletto and hit ecu data.Then i get the message from galletto to GRound pin 24 so i ground it and hold it and when i hit enter on my laptop immeditaely after i take ground away from pin 24. it reads out the ecu numbers,sometimes yes sometimes no,then i do the same procedure except i hit read ecu and it reads out the file and ask you to save make sure you make your file <exmaple>.bin.Its best to save as a .bin.And thats it. if you have pics of your harness please post or send.

Its a Galletto 1260.  I just tried on my buddy's EDC15P  TDI, which is directly supported and it didn't work.  So I'm wondering if I got a crap cable.  It just says 'errore sending wake'

yeah, I tried without pin 21 and it was the same.  Looks like I don't need it.
I know the ECU is working because I'm getting intrument cluster messages on the CAN line.

I believe galletto only  read and flashes me7.5 and me7.1.5 ecus not 7.1.1 but I could be mistaken.I believe there has to be a resistor soldered inline in order to enable boot mode on me7.1.1 ecus.
