Use knife to delete sealant.
Read flash 29F800 and post.
I'll make EZS dump you asked in PM from ECU, so no need to do it virgin.
Post also EEPROM from EZS you have.

Sorry, but you can not read flash with Xprog-M and UPA.
There are many programmers for reading 29F800.
Perhaps your friends have them, ask them to help

[clive_pather]

have a friend with ak500 will that help

[nguyennhatquang]

the best is BEEprog..
when u desolder the 29F800..do it very carefully. if not. u kill the AMD. It is very easy to die

[clive_pather]

how do u mean, eg use less heat?

GQ4X will do it

lol, these chips are usually a bi**h to desolder, use really good solder flux and lots of it, you may need to do one side at a time as they dont move to easily so a little gentle pressure will no doubt be needed

[doaa]

Should have Beeprog to read flash AMD 29F800


THANKS FOUR YOU

when u desolder that. u must heat 2 side care fully and jack it up in the same time.
if u only did in one side..u will kill the AMD

why? i only do 1 side at a time and never killed nothing. 2 sides at once on a chip that wont move easily means more heat through the chip which could also kill it

[nguyennhatquang]

oh u're so well..
i killed many AMD if i did in one side
tell me the secret..
temp...heat ??
please
