View The Full Version : Doubt checksum
Hello to all the forum, I would like to ask a question...
Finally, I have the file ori for my Grande Punto 1.3 multijet 90cv, so you can start studying for well also these hateful Marelli...
(it's the first that I'm going to write)
In the meantime, I started closing the egr, also because it begins to give me problems, but I noticed that Titanium does not recalculate the checksum.
In fact, the selection of the file ori I highlighted only reading BDM (28) and KESS (82)...
My doubt is...:
- it is necessary in some way to make it calculate to Titanium before write via OBD?
or...
- I try to write it anyway via the OBD (I have a KessV2 clone) as the same interface ricalcolera' the checksum?
according to me go via obd only if you have all the full backup of your ecu. if the kess is abandoning you in the process of writing you will have a nice problem to solve. if you already have all the backup then write, and if you block the reset by writing the complete file from bdm

for the checksum, the kess should calculate it before writing it without problems
I have the BDM full... as up to now my Kess I have never been disappointed trust is good but trust is better...
For the checksum, I know that does it automatically before burning, but I wanted to feel the experience of the forum...
If you write via obd on the basis of the programmer used the automatically corrects
then go to the obd and if it goes badly re-enter everything in the bdm
Then... will update on the situation...
To recap, my problem is that on the Titanium I have the driver for this ECU but not his family checksum, in fact, does not make the calculation nor on the file ori... I Believed that kess the correct automatically during the writing, but instead nothing...
This morning I tried the writing on the CAN and it worked fine, but the machine does not put in motion... after having rewritten the ori, however, was ok... I assume that the problem is the checksum is also why the kess asked me autocorrect!
According to you, how could I solve this big scab?
How do I calculate the checksum, I read that some correct it with winols...
I hope in your help because even if I write it as I study it!!!
I begin to hate those of Marelli!!!!!!!!!!!!!!!!!!!!!!!!
...I had come the doubt that the problem was that the file I was working on was obtained from a reading BDM... but if it were so it would not work, not even the ori...
Uhffa... how do I calcolarmi this checksum... do I have to somehow find the family for the Titanium....?
If I want to use a tool such as Checksum Calculator, it is feasible? They work for my purpose...?
write bdm.. should calculate it and write it without problems
Hello Marcuc, the problem is that I only have the kessv2... I could make it write in bdm from other people, but if you want to study well these marelli, can't do it if not I can write it when I want to!!
For this reason, I am looking for a different solution to the BDM
if placed in the file ori te the calculation I
Hello Alessio, I appreciate your offer now, I can't because I have with me the file ori the mod... but it still does not solve the problem because I should always ask you for the correction!
Sorry for the intrusion but from what I know there is a software called "VAG Checksum Fix" for bosch edc*.*, there will also be one for the Marelli?
And days that I try but I'm not finding anything
And days that I try but I'm not finding anything
and not trpverai nothing because they are all programs that cost big money, and nobody makes them available on the internet..
however, have you tried with winols?

guys I can not correct chk edc 15 on a class a170 I took the file ori has been modified with the ecm but my tool does not compute the checksum on edc 15 how do I? I have seen families available on the ecm makes me do it only on mercedes temic 400 cdi and opel sdi ? mountain the same ecu ?? it's good the same?
does not fit the same ecu, and even if it was not try, you have to correct some program such as winols or programs dedicated to the cks, I could say post the files that you fix, but then you could not download it due to lack of your messages.
and how can I do I tried it with winols and tells me chk not available for how many messages should I get? just yesterday I joined
