Yeah wrong chip then.

VCDS will never work though, only VCDS Lite.

i have now got the cable that shows up in nefmoto   time to try it all out. for just reading the map off the ecu do i need to go down the route of grounding the earth pin?

this is what im getting so far on my older 551 ecu

Connecting...
Starting slow init connection.
Connecting to address 0x01.
Slow init succeeded.
Switching to KWP1281 session.
KWP1281 connect info: 8D0907551   2,7l V6/5VT         D04

though im stuck on where to go to actually find the map to load into tuner pro.

if i click on read i get

Disabling Windows sleep mode.
Reading all ECU info.
Unable to validate programming session preconditions, attempting to continue.
Negotiating communication timings.
Successfully changed to new communication timings.
Starting diagnostic session.

please be gentle with me im still learning

Try bootmode with argdubs tool.

right with a few tweeks i managed to pull a file using argdubs tool. so im getting there slowly, cheers for the info peeps. so is this the same info i would have if i was pulling a file using nefmoto or something slightly different?

mine has the smaller memory, think thats where i was confused. ok so if i can pull info in boot mode should it work in nefmoto?

Nefmoto won't read the ecu in bootmode, it'll simply connect allowing you to confirm the ecu is actually in bootmode.

You need the galletto software to read the bin in bootmode. What you DON'T need is the galletto cable, as long as you have an ftdi based cable that contains a serial number (232bm/245bm devices do not, whereas 232r do), you can edit the galletto executable to work with your cable.

You can also change the serial number embedded in the cable to match the galletto executable, however this is not a viable option if you have a premium nefmoto license. Neither way is better than the other, both take less than a minute once you know what you're doing.

Yessir. Until you change the serial Galletto will display an error, something along the lines of "failed to open com port". Once the serials match it should work, if not, use the galletto drivers.
