griso 1100 dash

[harrytief]

Is a griso 1200 dash a direct replacement for a griso 1100 dash?
Harry

[Moto]

As I recall, yes. Best to check the part numbers. I'll do that when I get home.

[pete roper]

Yup. Griso dashes are all the same. If thinking of buying second hand make sure you get given the user code or it will be useless.

[Moto]

Yes, same number, GU0676000, as per Pete. Also his second point is very important!

[harrytief]

Not to argue with you Pete but the seller asserts that I do not need a code to install and use the dash. Is there any work around?
Harry

[Kiwi_Roy]

Wouldn't it likely be the default code, same as it shipped from factory?

[guzzisteve]

Most likely the guy bought it w/o knowing you needed the code or someone told him BS and is trying to unload it.
Dash's do not go back to a default, you need the code. No work around. Pete knows.

[janguzzi]

The default service code for Griso 850 / 1100 / 1200 8V is: 12425

Are you telling me the code is different than 12425
Anyone who changes that needs spiflicating
I understand the Key Code would be unique

[Chuck in Indiana]

Not the service code.. the owner's code. Without that, you're up the proverbial stream.

[Kiwi_Roy]

Is the owners code different for every single bike?
I don't recall using a code on mine other than the service code 12425 including when I added a pair of new keys.

Is the owners code some sort of a password added by the first owner, what is the point of that.

 

Never Mind, I see it on page 40 of the owners Manual ( I must have used that when I added the keys)
A stupid idea, how many times do we forget our passwords
True, you can write it in the manual but who takes that with them
I never use passwords on something unless its absolutely unavoidable and then I would write it somewhere for the next poor bugger e.g. on the back of the dash.

Knowing how hard it is to find someone who can even cut a new key from a blank, it's not something  any locksmith can do, the last thing you need to deal with is some stupid password. Rant Over

[harrytief]

Roy
Your rant is my rant as well!
I just spoke with my local dealer and he confirmed that a known USER code is necessary to activate a replacement dash.
He uses a service tech with a programme that cracks an unknown user code and keeps several harvested dashes around for replacement. No need to keep a spare on my shelf...I hope.
Thanks to every one who chimed in.

If you have two keys that have been matched to the dash you can recover the owner's code, as described in the Owner's Manual, p.  17, as seen on this clipping:





Then you can use that code to change the recorded value if you like, as seen on the previous page.





If you have neither the code nor the two matched keys you can follow Harry's lead -- especially if he tells who the dealer is.

You could also guess the code. Some use 12425 (the service code) for the user code, some use the last 5 digits of the VIN. No doubt some leave at the original setting, which I think is 00000, and others use 12345 or 54321, or the birthdate of their first child, etc.

Good luck.

P.S. Can somebody remind me what the point of this code is? How does it increase security?

So your dealer has a back door, I imagine he would want to reset the odometer to match the old one as well otherwise I can see owners just slapping another dash on to flip when the bike gets up in miles.
 
BTW, in NZ if you ask for a report on a bike you can find out if the Odo has been tampered with by the sequence of mileage readings from WOF inspections, I'm not sure if you can get anything like that in NA

Moto,
        Yes I suspect my PO left the code as 00000 otherwise I would remember being pissed off about it LOL

[guzzisteve]

Harry,  There is a back door, after all there is a plug under the seat that goes to the dash for updates. I did an update on Mana dash's at the dealer using the Axone. So anyway, who's the dealer? 2 Wheel or Corsa? May get more work if riders knew about that service.

[pete roper]

If the code is left at the default of 00000 every time you turn the bike on you'll get a message on the dash saying 'Don't forget to insert your user code.' I don't know why everyone seems to have a problem with it? It's pretty simple.

Pete

Pete
What do you mean, "it's pretty simple" ?

Until you meet a new to you lump of modified sand and you can't crack the code. LOL

[pete roper]

It's a lightweight security measure. In the event of someone trying to force the ignition switch they will encounter a problem that the dash will recognise that there is no key chip present so it will ask for the user code. If this is inserted the bike will start. If not? It's immobilised. Having the close option also means that if for some reason the antenna fails the bike can still be started. Without the code option once again the bike would be dead in the water.

Is it 'Necessary'? No, few things are! But it's simple and hardly arduous to use. As for making the code something hard to forget? How difficult can it be? I simply use the first five numerals of my birth date! I may be approaching senility but I can still remember my birthday!

Pete

PS. Roy, as long as you have two keys it's not a problem. You just use the ' Code Recovery' function in the dash.

[Moto]

Pete,

Thanks, now I remember having understood the point of it long ago.

Roy,

They won't be able to reset the odometer, I'm almost certain. Its value is kept in a special ROM, according to the findings of a fellow who cracked the RS50 Aprilia SR50 dash, and whose postings I found when I was investigating the related Griso (and Breva) dash. The value is encrypted, and he wasn't able to decrypt it or to reset it to anything but 000000. The federal government (and other national governments) have laws intended to prevent this kind of thing, I believe, and encryption is the mechanism Digitek used to comply.

The user code, on the other hand, was easily read and reset by this guy, whose user name on another site is now forgotten by me, but was mentioned in my long discourse on the Griso dash. (At least I think it was one of the things he could read/reset. It's not worth the trouble of going back to find out, I think.)

Moto

EDIT: Well, of course, I did go back to check what I just said. The mileage and the user code are both kept in a separate EEPROM, a kind of persistent memory module. Techrat1 was able to read and reset the user code, but only after disassembling the dash and soldering an interface onto it where the manufacturer had left some solder terminations that he recognized as being for that purpose. So the user code could be reset by someone similarly ambitious and knowledgeable. However, I would expect that a more direct approach of trying all 100,000 - 1 possible values might be what the dealer's software does. As for the mileage, however, that was protected by a checksum, and recorded in two separate locations. Techrat1 could not solve the problem of resetting it to any value except zero. (I was in error in saying that the mileage value itself was encrypted.)

Here's what he said:

"The mileage is the only thing that has any redundancy or checksum, it stores two identical copies of the mileage string in two separate pages, the mileage is always in KM, bit 2 of byte 6 selects the display between KM and Miles, but it is still always stored in KM... If you corrupt one page or the other it recovers and fixes itself, if you corrupt both it resets to ZERO KM and display in KM... I placed the cursor on the mileage and you can see at the side it decodes to "4442" that is the actual mileage on this dash... the last byte of the string is the check byte, it is not a simple checksum, I am not sure how it is calculated, maybe best left that way, since that prevents altering the mileage to anything other than zero.

"The user code is not protected at all and can be read straight out, the dash code is "91700" I bought this dash, code unknown..."

Moto,
        Wow, lots of information from Techrat, more than enough to put anyone off attempting it

It's somehow reassuring to know the odometer cannot be reset.

Thanks for digging it up

I remember Techrat's posts, and that's when I had an epiphany.. I really don't want to learn anything about this stuff.  I'm now an official curmudgeon. The Mighty Scura will be my highest tech bike from here on out..

I feel your pain, believe me.

We have a few really code savvy folks on this forum that are capable of modifying ECU codes for performance increases.  One has even constructed an ECU emulator (at least that's what I think I read.)  Could one of these code savvy folks take a look at what would be required to modify or remove a few lines of code in the dash programming that would permit it to totally ignore the key code? 

I'm fine with the stock ECU mapping on my 1200 Sport 2v and have been so for over 65000 miles.  (I know, I know, I don't know what I'm missing........)  but I think this would be a useful service, and would eliminate some of the uncertainty about swapping dashboards.

Actually, the correct solution would have been for Piaggio to own up to the problem, and replace a defective dash with a new one.  Not "take your bike to a dealer (as in flat tappet issue) and have them determine if you're worthy of an exchange," just do it, like Ducati, (after a lawsuit) finally did with their fuel tank problems.

Those savvy folk are reading and writing tables of parameters that the programs use, not the actual code of the programs. Though the program was written in a language or languages of some sort (e.g., C++), the source code is very unlikely to be present in the ECU. Instead, the program would by now have been compiled and no longer be readily interpretable by a programmer.

At least that's my understanding. The more savvy ones could still reply.
