I am working on a deutz fahr agrotron dashboard (tractor), the eeprom is CSI93c46SI, I dont need to write it, only to read and decode the hours. Tachosoftonline and carprog wont understand the code that I put there, so it is somehow wrong. Should that eeprom be conneted in reverse order? I couldnt find the pinout for this one.

Hi

This is 93C86 Eeprom from Mitsubishi Lancer 2010 gauge cluster. I want to make it read 265k km.
This code here should read 162 918 km but using Yazaki17 and BigJ teachings I cannot see how this code ends up saying 162 918 Km-s.
Any insight would be much appreciated. I want to learn how to do it myself. I have calculated correctly a couple of times but this stumps me.

From here I tried EB13 to Dec and I got 60179 which is stupid.....tried 1413 to dec I get 5139 then times 3 because its repeated 3 times.(15 417)
From there 1313 to Dec get 4883 times 13(repeated 13 times in code) gets 63 479 now add the 15 417 gets me to 78 896 and even if I put times 2 I get 157 792 which is the closest number that Ive gotten.

I feel dumb.....

EDIT: Im reading it with Ch341a reader(modded) and aadress length 10 and 16kbits. Am I even reading it right?

Dec /32, the result is converted to hexadecimal, then xor FFFF.

This is not a Yazaki algo, it is a Honda algo.

Hex to dec X 32 will get you close.

Hello,
please, can someone tell me where to find Ford Visteon algo for Land Rover Velar 2019 dash eeprom 24c64 (K8A2-10F844-JB) for mileage correction?
Thank You

[AlexGroos]

for the post with the hex converter.pdf there is some bad math in that. it says

"65536 + 10000 / 17 = 66124.xxxxx convert to hex is 1024C"

ok so 65536 + 10000 = 75536 then we divide by 17 = 4443.xxxx i have no idea how they came up with 66124 which makes all the rest wrong.??

According to the laws of bad mathematics, first we divide and then we add!

How to correct the odometer on a 2002 Mercedees CLK240 w209?

Hi Guys, I'm trying to figure out the algo for a Yamaha MT09 2014 (93c86). Somehow below it should read 2500km. Could someone explain to me the algo?

Thanks!!

[Johnner]

09 c4 in Hex = 2500 in Decimal

[datahop]

09 c4 in Hex = 2500 in Decimal

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.

Can someone help explain the Toyta/Lexus 93C86 Algo?
I saw a post but dont fully understand it. Could someone also tell me where in the hex to look?

Why don't you put a link to the post in here, then maybe someone will have look at it ?
