I received in my shop 03 BMW M3 , someone try to do some ebay tuning project with the dme... flash chips are replaced with 'MGEAR-CHIPTUNING M Power Phase-3" , now no communication with dme via orange head. Original flash chips are gone.

any suggestion?
maybe someone knows connection method via bdm100 for reading the flash now?

attached is all pictures

thanks:thrasher:

It is a siemens ecu, as works not with bdm100

You must through the pins connect to

if bdm100 can't read it, which tool will work in-circuit?

this ecu has two mcu and two am29f400 , what is the purpose of this?, both sets store same data on them?

i will need to make new flash chips for this ecu from scratch on the bench, old ones are no good... does anyone have bin for this am29f400 flash's?

now.... i need to edit something in the dumps to make them 'virgin' so they can be used in the other ecu?
