Title: A4 B5 1.8T 8D0 907 557 T M3.8.2 Post by: usuarionuevo on December 09, 2020, 08:53:15 AM Hello guys. I have some questions about the ECU.
I have read a lot about the ecu 3.8.2 but several things are not clear to me ... what if I am clear is that you have to put a socket, which I already have. but how do I read the chip and the second how do I write the new map on a blank chip. what is the process? do you have to do it in the bank, via obd? These 2 queries are not clear to me. Please someone help me. a hug.

To read old (no need - can find ori dump in the net) and write new chip use external programmer which is able to work with 27C1024 eprom chips in PLCC44 package. Like this one as example.

I use M28F102 No. For all chip types (27c1024/27c210/27F102/AT29c1024) the only possibility is external programmer.

What you think is more good.. Change the 8D0907557 ecu for 06A906018 and try inmo off and tume it with kess ooor buy the external reprogrammer and keep the chips style??
