Hi need new chips and you can add sockets or just solder back in after tuning with checksum

Move away the label and under it you will find the mark

[tiugrikas]

no mark under label found ! But I found on google by ecu number that is 27c512 ecu nr 028 906 021 ap , 0 281 001 317 .Maybe you have good mod files to share ? And one more question why both chips are needed on this type ecu's ?

Read you chips and post the files.
The file on older ones are usualy split in two files. Hi Low. when you join them u get the "normal" file
