Now I feel dumb, thanks for the clarification

Now I'm trying to figure out why the other digits are changing. I've downloaded the files on this thread https://www.digital-kaos.co.uk/forum...ight=mt09+2500 and compared them. Below in the red rectangles the ones that are changing and I don't understand why.

Many thanks again

Hi. Anyone? Is it because of the checksum? thanks!!

Hi. Anyone? Is it because of the checksum? thanks!!

I would think it is because you have re-read after you have added a few miles on

Hi, mates !
Happy new year !

BSI FL5 , car is 5008, 2017 , mileage 274949 km . Thank you for help to know !

Kansei algorithm anyone? It's been asked before but no-one has posted it yet. Lots of calculators out there so it's fairly well known I suppose, but I've never seen the algo itself.

Can anyone help explain the Denso Algo?

Mate, I would look at learning hexadecimal first. No point in explaining the partial script that you see in that post
There's more to that script

Post up, as I asked for before, a particular file that you would like explained, and we'll try walk you through it
Please don't post a script, as you obviously have no idea about where to even start with it

In order to understand lines of code/script, start learning Object Oriented Programming also
This will teach you all about functions, procedures, data types etc, so you will understand what is happening with the code



Thanks

My question is why is this below line used? I understand object oriented programming, just dont understand why there is a subtraction of FFFFFF. (Im assuming the $ indicated HEX?)

n3 := $FFFFFFF - (n2);

[dintech]

As an attempt to obfuscate the miles in the eeprom

[bunty95]

Thanks dintech.

Does anyone have the full Denso algo, couldnt find it on the forum and want to understand more then the small bit i found?

[tamakilla]

Can someone tell me how to calculate this one manually?

Does anyone know Ford’s mileage formula?

Can you tell me how to set up the display of km and degrees Celsius instead of Fahrenheit and miles on the dashboard of the Honda pilot 1? There is a firmware dump, I can edit it

Is the mileage formula known for a 2018 Kawasaki ZZR1400 (also known as ZX1400)?

I have not yet taken the bike apart or purchased hardware to do a EEPROM dump. I am trying to convince myself that I am able to do this successfully, with the help of kind folk.


Edit: By known I mean a) is it known and b) is anyone happy to share it with me? I would like to do this repeatedly without external reliance. But if 'proprietary' I would like to do so anyway.

Edit 2: I have downloaded both examples from here. Left hand side is 4155 and right is 1000km - please help with algorithm?

Edit3: Image compression is too much.

1000km
From offset 01A0:
1E 00 E1 FF 1E 00 E1 FF 1E 00 E1 FF 1E 00 E1 FF
1E 00 E6 FF 19 00 E6 FF 19 00 E6 FF 19 00 E6 FF

EDIT 4: I now think edit3 thread contains bad files. I have looked at dumps in zzr1400 threads related to users Nikola fpfhek and nasbadboy, all of which contain 'before edit' and 'after edit'. These files contain a simple repeated 4 byte pattern in the area that shows deltas between the files. Obviously, I have to trust the odo readings provided in the threads since I do not yet have a download of mine. I am also assuming these must be unsigned!

My workings with these new numbers - possibly someone can help from here:

		Nikola		fpfhek		nasbadboy
		52454	2495	44965	39500	1600	68823
	1	6D	42	D7	72	F6	6A

		92	BD	28	8D	04	95
		F9	FF	FB	FA	FE	F7
	2	6D	42	D7	72	FB	6A
....

		06	00	04	05	01	08
		95	BD	28	8A	04	9E
		F9	FF	FB	FA	FE	F7

EDIT 4: It feels close... help?!

Having spent a day on this I may start my own thread... it feels like this one is quiet.
