I hope some can contribute to this learning thread and help to clear some things up.  

This is also used in other cars and motorbikes (Honda PCX125, CBR 125-250 24c04)  , and in this example we will use a 2019 Hyundai Grand I10 24c16 (same algo I believe)

Refer to the pic below....

1d74 X 32 = 5c0a8 to decimal = 377000/32 = 11781 (roughly)

I suspect the next bytes are fine mileage adjustments because the first two bytes will not be accurate to small increments and the two byte calculation will not work over 102398 Km (using that algo with FF FF = 102398), so I think that the first bit of the next byte is the step up.

Over 102398 may be xx xx Ex xx (for up to 204798 etc.)

Haven't seen enough of these with over 100,000 Km yet to know for sure.

If someone can help with the last three bit calculations that would be appreciated.

Let's crack this new algo!

hello cluster
i think i have the calculator
if you have a dump to test it i will be more than glad to contribute with it

I don't use calculators they are unreliable in a lot of cases, and the offset is different from one to another. The main purpose of this thread is to learn how to do them manually with just hex editor and Wincalc.

Thanks though.

same algo as hyundai i10 2019 24c16....same mistery...lol

Algo is not km /32, algo is factor *25/128, etc....


example: if you need 128000km (Factor 128), is 128.000/128 to dec =1000 to hex = 3E 8X, so X is first CRC, that crc is obtained with movements to the right (4 -> rhs in win cal), after that, you must go through a conversion table where, for example if it is 1, now it will become 1D, in itself it is not difficult, only that it is long.

For those who know the calculation of the Nissan Navara 2006-2008 you can find out this, I've used a lot to make PCX and CBR250.
EX: km * 5.12, will work fine.
