Hi all

I have a 3.0 DCI Denso ECU from a customer water damaged

I will try to fix it ( somes smd are dead, but somes MCU pin are broken )

I would like to know if I backup the ecu with eprom 93c86 and flash 29F400

Can I put files to a donor Denso Ecu 3.0 DCI with different ecu numbers

Thanks for your answer

Problem solve by myself, repair MCU by soldering wires
