First I'd like to say thanks to Dreh for this posting, And I'll add my findings as well
I'm in the middle of a B3 TDI Swap ( much like Dreh was in a Mk3 TDI swap ) and wanted the cluster to match the body KM.
Following his setups got me Nothing more than -------- Across the screen of the cluster, when re-checking the EEPROM the first 5 addresses where changed to seemingly random numbers while the rest of the hex addresses i put in where correct.
so back to basics and seeing if i could find whats different between the two clusters, time to see how the math worked.
The Cluster had 139'370 KM on it, and the Hex read: 22 06.
Hex 22 06 converted to Decimal got: 8710 so clearly that was wrong.
what about 139370 to hex? 2206A!
The First attempt was to put the cluster to 83000KM or Hex 14438, So i dropped the 8 and programmed it in the EEPROM.
That got me 83007KM on the dash.
So lets try the desired number that i REALLY need, 82350KM or 141AE.
Programmed it, and it got me 82351KM
Honestly, Close enough...
I still dont know how the last hex place holder works, or how its converted to get the 100% Desired Reading, but within 1KM I'm good with.
If someone would like to play with it a little more, here is the code for the Bin file:
