hi ! in the ecus with two eprons welded like the plcc 27c010 which the best way of remap !
better to put a socket or it"s possible to flashed in circuit !
but i think they are a opt epron !

the ecu in cause is a edc 15 of passat tdi 1999 like this in the attch.


and for what epron should i replace !

thanks in advance !

You need to take them out and read the eprom in programmer like galep, wellon, batronix etc, then you need to buy a new eprom and load them with new software.

hope it helps

you won't flash this ecu through OBD , you need to :

unsolder 2 plcc32 -> read with external programer -> do the remap -> by 2 eeproms 29f010 and program it -> solder sockets -> put in programed eeproms -> do the tests .... :D

You forgot say most important detail, boths eproms are 8bits data_bus, for corrrect mapping must be edited in 16bits ;)

go here ! ALLDATASHEET.COM - Datasheet search site, Datasheet search site for Electronic Components and Semiconductors and other semiconductors. (http://www.alldatasheet.com/) and find the schematic of the chip you need ! but only a Theo can"t or recent be reflach in bord in case of motor management!
have a list I found and i gone put it here!
