thanks for dump ,,

the fin sections of this dump are encrypted. you can edit this dashcom with connected dash in car. dashcom decrypt the sections and write down dump decrypted. you can edit and reflash eeprom

Thank's so much freind, but what hardware use to flash this eeprom??

**michl12** · 2nd October, 2009, 08:05 PM

flashing solo offboard works with galep or similar programmers.

changing fin works easy onboard with vag dashcomcan or vag k+can.

if you not have k+can or dashcom try with any dumpdecrypters on this forum. i have seen this tools here.
thsi tools translate dump into decrypted ,, you can change teh fix ,, after this you must encrypt the dumps and write back.

k-line readed dumps are differnt to offboard readed dumps from eeprom. ( byteflips )

what you re talking about?

Read Micronas internal FLASH and EEPROM through JTAG.
there you will find all.

You wont be able to do anything through CAN diagnostic on a micronas tacho. Especially A3 2006-up

I hope you have the right tools to read a secured JTAG connection.
why dont you put in a 2004-2005 tacho with fujitsu. That one is easier to make virgin.
