The ori file was from old ECU before it broke down so yeah it is the original to this car but new ECU needs to be flashed and that was mod file what I sent

Your Original is 1037563605 and you Modified is 1037505922
I've corrected the Checksums for your Modified tune but not convinced it's correct for your car

Same ,mode not supported. Basically what happened, my ECU broke down.i always read and save file each car I own just incase for piece in my mind.so I got second hand ECU from eBay with same parameters only difference was code of engine, mine was cbab and this is cbbb but this shouldn't be a problem.Obviously I needed to sort out imobilizer so I sent both ECUs to a guy who sorted immo but car still wouldn't start.so what I'm trying now is to write original file from old ECU to a new ECU . Hope this make sense cos I'm lost now and don't know what to do . Thank you for your time mate

Using your original tune is a good option, the immo should work too.
The modified file you posted had strange changes anyways

Mod file what I sent you, I simply read and saved from new ECU what I got from eBay. Do u think that new ECU is faulty ? If so I can return it

If the hardware numbers match then simply use your original tune and job done

Hi mate.I dont know if you rember me but you helped to checksum my file. Couldnt make it work as later i found out that my new ecu was from passat but automatic gearbox not manual as mine and not 140ps but 170ps thats why there was so many differences. anayway now i got a new ecu which is right one but still need to write my ori file and hope its not too much to ask but i need to do checksum and i cant do it myself.any chance you could do it for me please? thank you
