Ducati 821 Hypermotard Guzzidiag

[Italianmachine]

Hi everyone,, I have tried to get my bike to connect to guzzidiag to no avail up till now (IAW7SM ECU), I have used all the methods at hand, bought the cables from lonelec etc, still nada, searching the net I have found out the following for Hypers (821 models I guess) :

I just had PMed the programmer of GuzziDiag and he told me, that he also found a 3-pin diagnostic plug (the old Ducativersion one) on wiring diagram of HS, but with wrong assignment of GND, which should not be the biggest problem to change on the connection plug (FIAT diagnostic cable)
Beard, the programmer from GuzziDiag/IAWDiag wrote me following to the Hyperstrada

Normalerweise ist GND auf Pin 2 (in der Mitte) und auf Pin 3 K.
Die Masse ist also (laut Plan) falsch, geht nämlich auf 1 (schwarz) anstatt auf 2.

translated:
normally ground is pin2 (in the middle) and K is on pin3.
as of HS plan mass is wrong, it is on 1 (black) instead of 2.

The information out there seems to be pretty vague, at least to me, although after reading it many times I think I might be getting there, just not 100% sure as it is pretty confusing, the other thing is trying to swap the cables in the fiat connector is nearly impossible, because of the way they are made, so if anybody got around this problem and would like to share their knolodge, It would be greatly appreciated

Hyperstrada? I had one, Fast and dangerous for me.. what are you trying to do with Guzzidiag?

[Italianmachine]

Hi fotoguzzi, Hypermotard sp, pretty much the same bike, they are good fun to ride , i'd  like to sort the fuelling out, turn off lambda sensors, install a different map ect 

[fotoguzzi]

You know about Ducatidiag right?

I do Brother in this bike's case is Melcodiag that has to be used, only thing with it is that is quite limited on what you can do, clear errors, oil and service reset and a few other things.
Not only is she a pain to work on but also difficult with everything else  I'll get there at the end... hopefully

If you are right that the ecu is iaw7sm, Guzzidiag can do it. reading and writing maps too. 

But A 821 could have a non Marelli ecu, where melcodiag is needed.

The connector on the bike is non standard connected  what Beard means. But you do have a 3 or 4 pin connector ?

Got there at the ends gents

Hi Paul ecu is defo an iaw7sm, the problem was as you say, the female three pin connector on the bike has the ground wired different to the other ducati models, so in order to get guzzydiag or iawdiag to be able to connect to the ecu, pin 1 and 2 needs to be swapped around on the male part of the fiat connector, it took me a while to work this out as most of the info that I could find online was quite confusing, mainly showing photos with the female end part of conector (16 pins) and at that end there is no cables connected to pin 1-2 & 3. The bike does have two connecting ports, a three pin on the right handside and on the left a four pin one which is were the gear indicator is connected to and that is the one that I use to connect melcodiag.

Dankjewel

Melcodiag uses Can bus I think, but iawdiag should do normal diag and be able to read/write maps too. Did you cut the 3 pin off ? You could have made a male<> female adapter cable that swaps the wires.

[Italianmachine]

Hi Paul,  that's correct mate Melcodiag uses  can bus. To be honest I've not done much with iawdiag yet, but the plan is that, sort out fuelling, install a map for termi without db killer and pipercross air fillter etc. I had two fiat connectors kicking about, I butchered one to help me work things out and the other one I used it to make the right connector 😁👍

Hi everyone, unfortunatelly back againg gents Although I have been able to conect Iawdiag with my bike, I don't seem to be able to use the whole program or the reader for that matter, I seem to have the following problems with Iawdiag:

No able to read faults, can not use Handle Self Learning or Throttle Self learning, the following message is displayed when triying to use any of them (ErrorError) , not able to use Co trim either.

Reader connects then I get the message Login Failed.

Any help would be greatly appreciated

Hi I'm new to the forum. I have a hypermotard 821 too and I  am in your identical situation too .After making the change to the 3-pin male cable I was able to connect to the bike but unfortunately the writer does not read the map and gives me the login failed error. Did you solve it??
 As regards the other operations (reset tps,error reading and reset desmo) I can do everything but by connecting to the 4 pin socket with melcodiag.

Hi Orazio, no yet brother, still working on it the little spare time that I've got at the moment, 😡😡 this bikes are a pain to work on I have used melcodiag too, straight forward thing  I will let you know if I ever crack the case 

[pauldaytona]

It could be that the 821 software in the 7sm does not allow the typical things with the 3 pin connector, with kkl, only with can bus. Why not use Melcodiag when it works?

Hi Paul, there's definitely something different between this model and the other bikes using 7sm ecu, I have tried many things, different laptops etc, no success yet, there's a few other things that i wanted to try but at the end i gave in and went down the easier-more common sense route, i have spoken to Bernd and he is looking in to things, I have offered to send him my ecu if it needs be, If after all that still unsuccessfull, I've two choices, wait for like you say further development with Melcodiag or sell the bike  don't like something i can not work on myself
