Hello guys and Happy New Year! As the title says i need some help with my ECU. So I have had an Audi A4 180bhp 2.5 tdi 4x4 with software chipped ECU increased up to 220 bhp and unfortunately it's been in an accident(totally crashed). I bought another one recently, exactly the same engine and ECU. My question is can I read and save eeprom of my old(creshed Audi) ECU and upload it on my new one to get again more horse power this is to avoid the replacement :) Thanks in advance for your help

If its same HW and SW number you can do it.

You can upload both dumps, we'll check for you

i think you dont understand,what he asked,
if you read eep. from old (crash ecu) and put to new ecu then car not start, immo data inside.
if both ecu have same SW: and HW then copy eep.from new ecu to old crash ecu.

Now i understand what he ask.

But for me its easier to write the old flash to new ecu, if same HW and SW

Thank you very much for the quick response. Would you enlighten me what do you mean by ''same HW and SW''? The serial number of both ECUs are exactly same only the last letter is different. Cheers

if both ecu have same SW(software) just copy eep.from new ecu to old crash ecu.
