What program are you using to dump the memory image from the ECU?

What memory address are you starting/finishing with?

Both N14 and B13 are 32K ROM images so they should read from 0x8000 - 0xFFFF

i currently use blatz NissanDatascan, purchased it merely for the fact that you get the consult cable with, http://www.blazt.biz/products/datascan.php, it has a function to “backup” the ROM,

I used the default setting on the application,
Start – 0000
Stop – 7FFF
Just due to the fact that I didn't know the start and end ranges, but will test these range, THX Very Happy
